[Introduction to Zhiyuan Xin] Grok of xAI opened its source as scheduled after seven days! Open the code behind Grok and let Musk slap his face at OpenAI. There are 8 MOEs with 314 billion parameters, and the weight structure is fully open. As soon as the project is launched, it has already snapped up 6k stars on GitHub.

When it comes to doing it, Grok of Musk xAI is really open source as scheduled!

Just now, xAI officially released the weight and architecture of the 314 billion parameter hybrid expert model Grok-1.

With a parameter of 314 billion, Grok-1 has become the largest open source LLM so far, four times that of Llama 2.

At present, xAI has not disclosed more information about Grok-1.

The information released by official website is as follows-

-The basic model is trained on a large amount of text data and has not been fine-tuned for any specific task.

The MoE of the-314B parameter has a weight of 25% that is active on a given token.

-In October, 2023, xAI started training from scratch using a custom training stack based on JAX and Rust.

Once online GitHub, Grok snapped up 6k stars and 586 Fork.

Project address: https://github.com/xai-org/grok-1.

Musk did not forget to ridicule OpenAI, "Tell us more about the" open "part of OpenAI …"

The new york Times commented that the original code behind the open source Gork is an upgrade of the future battle that the richest man in the world controls AI.

Will open source make technology safer or will it make it more abusive?

Musk, an "open source supporter", set an example and got involved in this heated debate in the AI community, and gave the answer with actions.

Xiao Zha also commented on Grok just now. "It didn’t really impress people. There are too many parameters of 314 billion. You need a bunch of H100, but I have already bought it."

A magnetic chain, the world’s first largest model open source.

This time, xAI open source Grok-1 is licensed by Apache-2.0, so users can freely use, modify and distribute the software.

The repository contains JAX sample code for loading and running the Grok-1 open source weight model.

Users need to download checkpoint, put the ckpt-0 directory in checkpoint, and then run the following code to test:

pip install -r requirements.txtpython run.py

This script will load the checkpoint and the samples in the model on the test input.

Because the model is large and the parameters reach 314B, a computer with enough GPU memory is needed to test the model with sample code.

Moreover, because the implementation efficiency of MoE layer in this repository is not high, this implementation is chosen to avoid the need to customize the kernel to verify the correctness of the model.

Through the Torrent client and the following magnetic link, you can download the weights.

magnet:? xt=urn:btih:5f96d43576e3d386c9ba65b883210a393b68210e&tr=https%3A%2F%2Facademictorrents.com%2Fannounce.php& tr=udp%3A%2F%2Ftracker.coppersurfer.tk%3A6969&tr=udp%3A%2F%2Ftracker.opentrackr.org%3A1337%2Fannounce

More details

Andrew Kean Gao, a Stanford researcher, browsed model.py and introduced more information about the architecture of Grok. There are no additional clauses for the 314 billion parameters.

8 mixed experts (2 active experts), 860B active parameters. It uses rotation embedding instead of fixed position embedding.

-tokenizer vocabulary: 131,072 (similar to GPT-4) is equivalent to 2 17.

-Embedded size: 6144(48*128)

-Transformer layer: 64 (each layer has a decoding layer: multi-head attention block and density block)

-Key size: 128

Multi-head attention module: there are 48 query headers and 8 key values.

Dense block (dense feedforward block):

-Width factor: 8

-The hidden layer size is 32768.

Each token selects 2 out of 8 experts.

The embedding size of the rotation position is 6144, which is meaningful, and it is the same as the input embedding size of the model.

-Context length: 8192 token

-Accuracy: bf16

Finally, attach a summary map.

Netizen: Open source battle is coming.

The AI community is already boiling!

The technical community points out that the highlight of Grok is the use of GeGLU and normalization method in the forward feedback layer, and the use of interesting sandwich norm technique.

Even OpenAI employees have expressed their strong interest in Grok.

Jim Fan, a senior scientist in NVIDIA, said, "The largest open source model in history was trained by a world-class team and released through the magnetic chain Apache 2.0.

314B parameter, mixed expert model (8 experts and 2 active). Even the active parameter scale (86B) exceeds the largest Llama model. I can’t wait to see the benchmark results and what kind of applications people can build with it. "

Sebastian Raschka, an AI researcher, said that Grok is more open-source than other open-source modular models that usually have restrictions on use. However, it is less open source than Pythia, Bloom and Olmo, which provide training code and reproducible data sets.

Boris Dayma, the founder of Craiyon, analyzed the code of Grok-1 in detail.

Netizen indigo said that in order to "understand the universe", it seems that the xAI team deliberately set the parameter as "pi 314B", which is the largest open source model at present. It is expected that Llama 3 will join Grok’s open source battle in June this year.

After Grok opened the source, a big wave of fine-tuning is coming.

The first generation Grok has surpassed Llama-2-70B.

In November, 2023, xAI launched its first generation of big language model, Grok, and formally joined the big model war.

At that time, Grok used Twitter as part of the "Premium+" subscription service, with a monthly fee of $16.

XAI said that Grok’s design was inspired by The Hitchhiker’s Guide to the Galaxy, which can answer almost all questions and help people pursue understanding and knowledge regardless of background or political stance.

Grok’s original version, Grok-0, had 33 billion parameters, and then xAI introduced Grok-1, which was improved several times to support the Grok chat robot on X.

According to the data released by xAI, in a series of benchmark tests such as GSM8K, HumanEval and MMLU, Grok-1 outperformed LLMA-2-70b and GPT-3.5, although it was far from GPT-4.

At that time, Grok was not only able to handle the user content generated in real time on the X platform, but also had a little sense of humor, which injected a little vitality into the simple AI.

While providing information about the latest hot events (whether political or sports), it can also be clever and even occasionally sarcastic.

Why did Musk choose open source?

After mocking OpenAI as "CloseAI" several times, Musk really chose to open his own big model.

Of course, there must be commercial considerations behind this.

As a market leader, OpenAI has no reason to open source the model code behind ChatGPT.

Now, by releasing Grok’s code, Musk firmly rooted himself in the latter camp. This decision may make his xAI surpass Meta and Mistral AI.

Llama’s open source has brought many benefits to Meta, and almost made Xiaozha climb out of the quagmire of the meta-universe.

Mistral AI, which is just a small start-up, is also famous for its open source strategy and is recognized by the industry as "OpenAI in Europe".

The open source version may encourage developers and potential customers to adopt their own models more quickly, which actually plays a marketing role.

The feedback and improvement from the developer community on the open source version of Grok may also help xAI to speed up the development of new versions, which can choose to open source or keep exclusive rights.

For example, like Mistral, it promises to continue to release open source versions while retaining the most advanced models for paying customers.

Musk has always been a supporter of open source technology. Even Tesla has opened the source code of some parts of the car, and his social media platform X has published some algorithms for content ranking.

"There is still work to be done, but this platform is by far the most transparent, truth-oriented and not a high threshold platform," Musk said today in response to comments on the open source X recommendation algorithm.

Although OpenAI is still far ahead in the AI field, the war between open source and closed source is far from over.

Should the AI model be open source? Some people think that this powerful technology must be protected from intruders, while others insist that the advantages of open source absolutely outweigh the disadvantages.

As a market leader, OpenAI has no reason to open source the model code behind ChatGPT.

Now, by releasing Grok’s code, Musk firmly rooted himself in the latter camp.

This decision may enable his xAI to finally surpass Meta and Mistral AI.

　　According to the data, the control project of the project crosses beijing-shanghai railway and crosses the Beijing-Shanghai high-speed railway, and it is constructed synchronously with three projects and four bridges of the track line and Tuanhe Road, and it is successfully completed by using the "skylight point" of railway transportation in 90 minutes in the morning. Make full use of BIM technology in the process of project implementation, generate the whole deduction before turning, accurately calculate and improve the control ability, and greatly reduce the safety risk. The synchronous swivel project of "Three Lines and Four Bridges" led by Beijing Investment Co., Ltd. pioneered the cluster swivel construction of long-span bridges across the railway in China.

Blind people dare not take the blind road: I don’t know what is waiting for me ahead.

On the sidewalks of the city, there is always a strip of blind roads. For people with visual impairment, the blind road is a "static eye". They judge the direction of the road through the detection of the blind road brick by their feet and blind poles. However, in an interview recently, the reporter found that there are many obstacles on the blind road in Shijiazhuang street, which seriously affects the travel of the blind and even brings them danger.

phenomenon

The bike is parked on the blind road.

On both sides of the blind road on the street sidewalk, a row of cars stopped on one side, and a row of bicycles and electric cars stopped on the other side. The rear wheels of non-motor vehicles occupied a large part of the blind road. This is the scene that the reporter saw on a service road south of the intersection of Ping ‘an Street and Huai ‘an Road on the afternoon of July 31st.

"The blind road has become like this. We people with healthy eyesight have to be careful when passing. How can the blind get by?" A gentleman passing by here lamented.

On the streets of Shijiazhuang, such a situation is not uncommon.

The blind road in front of northland supermarket in Zhaiying South Street is occupied by a row of bicycles and electric cars. There was a special parking space for non-motor vehicles in front of the supermarket, but because the parking space was full, someone parked the car directly on the blind road for convenience.

There is also a phenomenon that the blind road is occupied by bicycles next to the entrance of Beiguo Mall Station and Northern Song Dynasty Station on Metro Line 1. Bicycles are parked in disorder, which not only occupies the blind road, but also blocks the pedestrian passage. Many pedestrians have no choice but to bypass the road.

In front of the book building, some cars parked directly on the blind road, and they stopped in a row, completely blocking the blind road.

Roadside facilities play "edge ball"

In some places, obstacles have been erected on blind roads.

On a section of service road near Jianhua Street on Donggang Road, a row of iron piles with a height of 20-30 cm were erected close to the blind road. In some places, even irons stood on the other side of the blind road, and a short section of iron piles even circled the blind road into the parking lot. The motor vehicles parked here just cover the blind road. A lady who lives nearby said worriedly, "For blind people, I’m afraid they will trip on such a blind road."

On Ping ‘an Avenue, there is a small iron house next to the blind road, which also makes people worry about the blind people passing through here, fearing that they will bump into the house when they walk.

Mahjong table on the blind road.

In addition to some vehicles or facilities occupying blind roads, some citizens also occupy blind roads when setting up stalls or having fun.

On Zhaiying South Street, several citizens put tables on the blind road and played mahjong, with some onlookers watching the battle.

The citizens who played mahjong said that they didn’t realize that they occupied the blind road. They just felt that it was cool under the tree and few people passed by, so they played mahjong here.

The reporter also saw the interruption of blind roads in many road sections. On a section of Ping ‘an Avenue, not only the blind road was interrupted, but also a manhole cover was tilted, which simply became a "trap".

affect

Blind people usually dare not go blind.

Wang Huaijie is the owner of a blind massage shop on Jianming North Road. He told reporters that he was hit by an obstacle on the blind road when he was walking. This kind of thing has happened many times. "Once in the street in front of my shop, a sorbet seller put the sorbet box on the blind road, and people were not around. I couldn’t see it, so I went straight ahead and bumped into the sorbet box. " Wang Huaijie said, fortunately, he walked slowly, and there was nothing serious, but he was shocked at that time.

"On the road in the middle of the tree, inclined cables with telephone poles pass through the blind road, high and low. Walking through there, you often stumble when you meet the low ones, and sometimes there are wires on the high ones. Once I went to my sister’s house and passed there, and I was scratched by wire. I don’t know who to look for, I can only admit that I am unlucky. " Wang Huaijie said, "Some blind roads are too close to tree pits or green areas, so we can’t see them. It’s easy to walk askew. If you accidentally step into a mud pit on rainy days, your shoes and socks are wet."

Speaking of the impact of obstacles on the blind, Wang Huaijie has a lot to say. He said that some vendors will occupy blind roads, which is not bad, and stall owners will remind themselves when they see it. The most troublesome thing is that sometimes bicycles or other sundries will appear on the blind road, and no one will remind him that he is often tripped or injured.

Mr. Geng, the owner of another massage shop, said that he also had the experience of almost tripping over wires. Sometimes the blind road disappears when walking, leaving him at a loss. "Now I don’t take the blind road, because I don’t know what’s waiting for me in front, or it’s safer to walk by the curb." Mr. Geng’s words represent the voices of many blind people. They usually prefer to walk along the road in the non-motor vehicle lane when they go out, thinking it is safer. Some blind friends simply avoid traveling alone, but they really need to go out and let their families accompany them.

It is understood that blind people need to constantly compose pictures in their minds when walking, and build a three-dimensional picture with the feeling and hearing under their feet. The blind stick in their hands is like a detector, and they can check the road conditions 1 meter away at any time. When there is an obstacle at a certain point in this picture, it is necessary to detour, and this obstacle point will stay in this three-dimensional picture for a long time, and they may not dare to pass here next time. Because of this, many blind people are afraid to take the blind road because of the obstacles on the blind road.

hotline

Which department can take care of the blind road?

The blind road is occupied. Is there any department that can manage it?

The reporter called the Shijiazhuang City Management Hotline 12319, and the staff of the urban management department said that this situation needs to be understood by relevant personnel before replying.

Then the reporter called the hotline of Shijiazhuang Mayor 12345, and the staff said that they would report it to the relevant departments and hand over the matter.

sound

Blind roads are the standard of urban civilization.

The blind road is the standard of a city civilization. For everyone who needs to use the blind road, this road is "just needed". However, due to various reasons, there are many obstacles on the blind road, which makes the blind people afraid to take the blind road, and the blind road has become a decoration.

Shi Yunfeng, vice chairman of Hebei Association for the Blind, said that the occupation of blind roads is an old topic, and the state has always attached great importance to the travel of blind people, requiring all urban public roads to have blind roads. However, in real life, many citizens simply don’t have this awareness. It is not uncommon for bicycles, cars and stalls to occupy blind roads. Although they have appealed for many years, they have not been well solved.

"Now it is not only unsafe for disabled people to walk in the blind road, but also dangerous. When they walk, the wire hanging on the blind road cuts their faces, or they rub against other people’s cars and even fall into the sewer when they walk. The blind road not only failed to guide the blind to walk, but became a’ road killer’. " Shi Yunfeng said that there are many irregularities in blind road construction. In some places, blind roads are often laid according to the direction of roads, but the practicality of blind roads is ignored. "Builders don’t use them, users don’t have the right to speak", so that there are manhole covers and stay wires in the middle of blind roads.

"There are currently 79,000 visually disabled people in Shijiazhuang, and the occupation of blind roads and the irregular construction have affected their lives; For the country, it is also a huge waste that blind roads can’t be used when they are built. " Shi Yunfeng called on the relevant departments to effectively deal with this situation, and hoped that blind friends as users could be involved in the design and laying stage of blind roads, so as to effectively make blind roads play its due role.

　　Some artificial lanes are congested, the pass card is not recognized, and the toll amount is displayed incorrectly; Some car owners feel that the charges have increased … … Since January 1st, when the provincial toll station of expressway was cancelled and the new fast toll collection system was connected to the grid, the system was generally stable, but there were also some new situations and problems. On January 17, Wu Dejin, director of the Highway Bureau of the Ministry of Transport, and Wu Chungeng, spokesperson, responded to social concerns at the regular press conference of the Ministry of Transport.

　　After the station was withdrawn, the freight car charging standard was re-approved.

　　All localities will review the standards to prevent illegal price increases.

　　Some car owners reported that the toll became higher after the station was withdrawn. Why did this happen? Is the charging method changed?

　　"In the process of withdrawing the station, the toll standards of passenger cars in various places have not been adjusted. What has changed is the rounding rules of the fee and the accurate charging according to the actual traffic route; In order to realize the fast charging of trucks without stopping, the charging of trucks was changed from charging by weight to charging by model, and the provinces also re-approved the charging standard of trucks. " Wu Dejin said that when the Ministry of Transport previously asked all localities to verify the freight car toll standards, they should strictly follow the requirements of "two guarantees and one reduction", that is, to ensure that the overall burden of freight car tolls will not be increased under the same traffic volume conditions, and that the toll payable for each type of toll vehicle in the standard loading state will not be greater than the toll payable for the original toll by weight, so that the tonnage corresponding to the new toll standards will be at least 10% lower than the full tonnage.

　　Wu Dejin introduced that before this, all localities had formulated relevant charging standards through legal pricing procedures, and all of them were made public and interpreted before January 5. The Ministry of Transport has also asked all localities to carry out in-depth review of charging standards. "Those who do not meet the requirements should be implemented by lowering the charging standards or differentiating fees, and they must never take the opportunity to raise prices in violation of regulations and increase the burden on enterprises. Regarding the problem of rising rates reflected by everyone, we will instruct the relevant provinces to verify one by one, find out the reasons, properly dispose of them according to law, and earnestly safeguard the legitimate rights and interests of the public. "

　　Wu Dejin also told reporters that in order to further improve the transparency of charges, the Ministry of Transport is organizing relevant units to develop apps or small programs. "After being put into use, the public can directly input the starting and ending points and driving routes and find out the corresponding tolls by themselves."

　　Troubleshoot system technical problems and improve information push settings.

　　Strive to realize the stable operation of the charging system before the Spring Festival.

　　At the beginning of the grid connection, the new toll collection system was unstable, which caused inconvenience to some ETC users’ normal travel. "In response to these problems, we set up a technical support team to organize technical backbone teams to guide provinces with weak foundations and unstable operations. Continuously optimize the system from the aspects of upgrading the entrance and exit lane software, optimizing the charging calculation module, and improving the recognition rate of ETC gantry system, so as to improve the operating efficiency and the accuracy of charging. " Wu Dejin told reporters that according to incomplete statistics, the lane system software has been upgraded more than 200 times, the rate calculation module has been upgraded and optimized more than 800 times, and the customer service APP and SMS applet have been tuned more than 30 times. "Recently, we have deployed ‘ Clear action ’ Re-examine and sort out the system, and strive to complete all the problems before the Spring Festival to promote the overall operation of the system. "

　　There are also some car owners who report that they frequently receive short messages of deduction when using ETC to take the expressway, which is quite puzzling. There are also many car owners who hope to achieve "one-time settlement and display the total cost" for export.

　　To solve these problems, Wu Dejin explained that after the station was withdrawn, the accurate charging of the expressway was carried out through the ETC portal system, that is, every time the vehicle passed an ETC portal, the system would charge accordingly. "The system should have formed a complete bill for the whole process of deduction, and then pushed it to the owner through SMS or APP. At present, the problem of frequent push is mainly due to the instability in the early stage of system switching, and sometimes the bills of sub-sections are pushed to customers. " Wu Dejin said that the Ministry of Transport has asked all localities to improve the information push system in strict accordance with the requirements of the technical scheme, so that the public can get relevant information accurately and timely.

　　Regarding the issue that the ETC lane exit does not display the full toll, Wu Dejin responded that the new networked toll collection system is an offline system. When calculating the full toll of a car at the ETC lane exit, it is necessary to call the toll collection records of the car from various ETC portal systems along the way, and the calculation time of the system will be longer than the time for the vehicle to pass through the ETC lane (270 milliseconds). "According to ‘ Access priority ’ Principle, ETC vehicle ‘ Pass first, then deduct the fee ’ The new charging system informs the whole cost through SMS and APP inquiry, but in the initial stage of system switching, both methods were not implemented satisfactorily. "

　　Wu Dejin told reporters that at present, the Ministry of Transport has deployed all localities to implement SMS push and APP inquiry in a timely manner in strict accordance with the technical plan to ensure that the public can know the toll amount in time. "At the same time, we have also studied and formulated the technical plan for the fee display according to the requirements of the majority of car owners. The next step will be to accelerate the related work and strive to implement it as soon as possible."

　　Measures are being taken to keep the system running and the site unblocked.

　　Never increase the travel burden of enterprises and people.

　　"With the continuous running-in and improvement for more than half a month, the operation of the charging system is constantly improving." At the meeting, Wu Chungeng introduced the traffic situation since the withdrawal of the station with a set of data: At present, the ETC utilization rate of buses has remained at around 76%, and the ETC utilization rate of trucks has increased from 17.04% on January 1 to 19.65% on January 14; The speed of vehicles passing through the entrance and exit toll stations increased by 13% compared with the same period of last year; The number of toll stations with daily average congestion of more than 500 meters at entrances and exits decreased by 21% compared with the same period of last year, and the average congestion duration decreased by 10% compared with the same period of last year; The time for buses and trucks to cross provincial boundaries has been reduced from 15 seconds and 29 seconds to 2 seconds and 3 seconds respectively.

　　"To cancel the provincial toll stations of expressways, it is necessary to comprehensively upgrade the software and hardware systems of all toll stations and toll lanes in the country to achieve interconnection, interoperability and mutual recognition." Wu Chungeng said that in view of the problems in the initial stage of system switching, the transportation system has taken a series of measures to ensure the system operation and smooth stops: establishing a three-level dispatching linkage mechanism between the Ministry of Transport, the Provincial Department of Transportation and the expressway toll station, and implementing 24-hour monitoring on the national network toll stations and expressway toll stations. If it is found that the length of congestion is more than 500 meters, the coordination mechanism will be started immediately to timely dispatch and divert to prevent large-scale traffic jams; Seriously accept complaints from the public, verify, deal with and reply to the clues reflected by the public one by one, and safeguard the legitimate rights and interests of highway users.

　　"Next, we will earnestly improve our service awareness, solve the existing problems as soon as possible, and never give them to the broad masses of the people ‘ Add a block ’ Never increase the travel burden of enterprises and people, so that more people can enjoy the reform dividend and enjoy the benefits of convenient travel. " Wu Chungeng said.

Trump’s "olive branch" was categorically rejected by Iran.

Just before Iran recently held a routine annual military exercise in advance in the Persian Gulf, Trump, who recently sent Iran a "capital tweet" implying the use of force, unexpectedly said that he was ready to meet with Iranian leaders at any time without preconditions: "I am willing to meet, especially when I may face problems such as war, death and famine. There is nothing wrong with meeting. " "If they (Iran) want to, I am ready to meet them at any time." "There is no precondition. If they want to meet, I will. " Trump’s bizarre "olive branch" was not only categorically rejected by Iranian conservatives and moderates, but also failed to change Iran’s Persian Gulf military exercises as scheduled, and was criticized by the media at home and abroad.

Since Trump announced his withdrawal from the Iranian nuclear deal on May 8 this year, the diplomatic game and public criticism between the United States and Iran have never stopped. At present, the international community, especially international public opinion, is doubly concerned about whether the game between the United States and Iraq is developing in the direction of opening peace talks or evolving in the direction of opening war? Opening peace talks is undoubtedly big news, and opening war is even bigger news. This is undoubtedly another unpredictable suspense that Trump has created for the world. In my opinion, in the short term, there is no possibility for the United States and Iraq to start negotiations, let alone war. The two sides are still in the stage of diplomatic game and public opinion attack and defense between pressure and anti-pressure, sanctions and anti-sanctions.

Trump’s diplomatic "soap opera" was embarrassed.

Trump’s casual attitude is not serious, and it is naturally difficult to cause serious treatment and response from Iran. Trump’s loose talk shows that the United States and Iraq can hold unconditional negotiations, which is a manifestation of his capricious and consistent style. Just a few hours before Trump’s speech, US Secretary of State Pompeo also said that the United States and Iran would never hold unconditional talks, and Pompeo was nicknamed "the mouse in the maze" by the media.

Although Trump’s diplomacy is unpredictable, it has also formed a certain "diplomatic routine" on many crisis issues: first, it issued extreme threats, then changed its position, held talks, and finally announced its victory. The most typical case is Trump’s North Korean diplomacy. However, the Iranian nuclear issue is not only fundamentally different from the DPRK nuclear issue, but also Iran’s complicated bureaucratic system, especially the dual structure of conservative and reform forces, and the constraints of religious leaders on the president are very different from North Korea’s power structure, and the geopolitical environment in which the two hot issues are located is also very different. What’s more, the US-DPRK summit was realized under the pressure and communication of Trump for eight months after he took office.

Therefore, Trump’s loose talk about holding US-Iran talks was also accused by the media as a "diplomatic soap opera", and Iran, which has been engaged in diplomacy on the Iranian nuclear issue for 15 years since 2003, naturally will not make a positive response at will. The prospect that it is difficult for the United States and Iran to hold negotiations in the short term is just as Gerald Blank, an expert at the Carnegie Endowment for International Peace in the United States, said: "Iran’s domestic political structure is much more complicated than that in the northern part of the peninsula, and it is not interested in diplomacy with the United States, especially after Trump asked the United States to withdraw from the multinational agreement known as the Joint Comprehensive Action Plan." "At present, if anyone in the Iranian government tries to contact Trump, they are severely criticized by others."

The reaction made by Iran also proves this point. Motahari, deputy speaker of the Iranian parliament, pointed out: "After Trump made an arrogant talk to Iran, negotiation is impossible. This is an insult. " Iranian Interior Minister Fazley said: "The United States cannot be trusted. How can people trust after the United States is arrogant and unilaterally withdraws from the nuclear agreement? " Arribi, director of the Iranian project of the World Crisis Group, commented that "no Iranian leader will meet with the US president who has repeatedly threatened Iran, attacked the Iranian leadership and violated the nuclear agreement at this time."

"Old hatreds and new foes" make the United States and Iraq not qualified for negotiations.

In essence, Trump’s idea that the United States and Iran can negotiate unconditionally is more of a diplomatic strategy, which not only alleviates the international community’s widespread criticism that the United States unilaterally withdrew from the Iranian nuclear deal, but also shifts the responsibility for regional tensions to Iran. At the same time, it is also a strategy to aggravate Iran’s domestic contradictions and disrupt Iran’s domestic political ecology. However, its arbitrariness and hypocrisy can be described as obvious, and Iran, which has rich diplomatic experience, will naturally not take it.

Of course, the deeper root of the difficulty in holding negotiations between the United States and Iran lies in the serious distrust accumulated by the confrontation between the United States and Iran in the past 40 years since the Islamic Revolution in Iran in 1979. The contradictions between the two sides spread throughout the social system, ideology and practical interests. From the beginning of the Islamic Revolution when the United States broke off diplomatic relations with Iran to the hostage crisis, from the 1980s when the United States supported Iraq to confront Iran in the Iran-Iraq war to the Clinton administration’s containment policy, to the Bush administration’s characterization of Iran as an "axis of evil" and its long-term sanctions against Iraq, and now the Trump administration brazenly withdrew from the hard-won the Iranian nuclear deal and exerted extreme pressure on Iran, it can be said that the old hatred between the United States and Iraq has not been solved, and new hatred has been added.

Therefore, negotiations between the United States and Iran are not realistic at all, just as Mehmetali Jaafari, commander-in-chief of the Islamic Revolutionary Guard Corps, said: "Iranians will not allow government officials to meet with the Great Satan." of course，Contact between the United States and Iran through a third party is not excluded. Some analysts pointed out that Oman’s foreign minister visited Tehran and Washington one after another last month, which is likely to play an information communication role between the United States and Iran.After Rouhani came to power in 2013, it was Oman that brokered the bridge between Iran and the United States, which finally led to the resumption of US-Iran contacts and Iranian nuclear talks. According to reports, Trump had sent the message of holding bilateral talks to Iran eight times before. However, the United States kept pressing and shouting about the talks. In addition, the Iranian nuclear deal involved China, the European Union and Russia, which made Iran not easily hold bilateral talks with the United States, and even more afraid of falling into the diplomatic trap set by Trump.

Judging from the future trend, the possibility that the United States and Iran will return to negotiations will not be ruled out even if the United States exerts certain pressure on Iran and forces Iran to compromise in some areas of the 12 conditions put forward by the United States (such as Syria and other issues), but this will not happen overnight, and it is difficult for Iran to abandon other parties in the Iranian nuclear deal and negotiate with the United States alone.

The weight of war: the United States and Iraq can’t bear it.

From the perspective of the United States, although Trump has changed the Middle East policy during the Obama era since he took office, he has continued to exert his strength on the three hot issues of Syria, Palestine and Israel, but its essence is still to maximize the benefits with the minimum investment, and its core is to consolidate the alliance with Saudi Arabia and Israel and profit from it by shaping Iran into a regional core threat. However, Trump, who gives priority to the interests of the United States, revives the domestic economy and ensures the victory of the mid-term congressional elections, has no systematic plan to go to war with Iran rashly. This may be one of the specific reasons why Trump recently said that the United States and Iran can negotiate unconditionally. Its purpose is to cool down the situation in the Gulf region, which is becoming more tense in the context of Iran’s recent military exercises.

In essence, the United States should be well aware of the disastrous consequences of going to war with Iran. If it chooses a "preemptive" war to completely overthrow the Iranian regime, it will trigger regional turmoil and even a full-scale war, and will impact the international energy market and the whole world economy. If limited military strikes involving Israeli, Saudi and other allies are chosen, the United States will not be able to change the Iranian regime in a short period of time, and Iran will definitely choose to threaten to block the US military bases in the Strait of Hormuz and intensify the conflicts in Syria, Yemen and other regions in an all-round way, and the forces fostered by Iran in the Middle East will continue to create troubles. Iranian President Rouhani warned that the war between the United States and Iran would be "the mother of all wars", and this is the profound meaning. The strategic depth of Iran and the Persian nationality’s resistance to power will also be feared by the United States, and the lessons of the United States in Iraq and Afghanistan are just around the corner. Therefore, if Trump is still rational, it is unlikely that the United States will choose to launch a war against Iran.

Iran is facing more serious challenges. The contradiction between Iran’s conservatives and reformists has intensified after the United States restarted sanctions, and the people’s livelihood crisis aggravated by a large number of foreign capital fleeing, currency depreciation and soaring prices has made Rouhani face the phenomenon of "second term curse" of the president in Iranian politics (that is, both reformist and conservative presidents will hit a wall in their second term and end up in a bleak way, and hostile factions will come to power in the next presidential election) more serious, while the United States has become Rouhani’s "second term curse". At present, coping with economic difficulties internally and alleviating the economic crisis; Saving the Iranian nuclear deal from the outside world and easing the pressure of U.S. sanctions are the top priority of the Rouhani administration, which makes it not take the initiative to choose war at all. At present, although Iran has held a very high-profile military exercise, Iran will not easily take actions such as blocking the the Strait of Hormuz to aggravate tensions without a comprehensive or limited military strike by the United States.

Based on the above factors, in a certain period of time in the future, the United States and Iran will continue to struggle mainly in the fields of diplomacy, economy and public opinion, supplemented by mutual deterrence in the military field, and even the friction between the two sides in a third-party battlefield such as Syria will not be ruled out, but it is unlikely that the two sides will engage in direct local wars and total wars.

Of course, the United States will hope that Iran’s economic collapse and even regime collapse will be caused by extreme pressure, and Iran’s political and economic difficulties will naturally continue to intensify. However, Iran’s political toughness is much higher than that of Arab countries where regime changes have taken place before. The political system of the Islamic Republic, which combines religious centralization with democratic elections, a relatively complete bureaucratic system, the mutual restriction between the two forces of reform and conservatism, the absolute loyalty of the Islamic Revolutionary Guard Corps, and the regime’s ability to resist pressure for a long time under war and sanctions, are all factors that enable the Iranian regime to maintain its resilience.

Therefore, before the end of the mid-term elections in the United States this year and the deadline set by the United States for the termination of trade relations with Iran (November 4), the relationship between the United States and Iran will remain in a stalemate, and its future development remains to be observed and evaluated.

In the process of house decoration, the treatment of blank wall is a key link, which directly affects the quality and effect of subsequent decoration. The following will introduce in detail the proper treatment method of blank wall and the aspects that need to be paid attention to in the treatment process.

First of all, a comprehensive inspection of the blank wall is the first step. It is necessary to carefully check whether there are cracks, hollowing and other problems on the wall. You can tap the wall with a small hammer and judge whether there is empty drum by sound. If cracks are found, small cracks can be treated with special crack repairing agent; For larger cracks, it is necessary to cut the cracks first and then fill them with cement mortar. If there is an empty drum, the empty drum part should be eradicated and repaired with cement mortar again.

Followed by the treatment of the wall base. This includes cleaning the dust, oil and other impurities on the wall. You can use brooms, vacuum cleaners and other tools to clean up and ensure that the walls are clean and tidy. After that, choose the appropriate treatment method according to the flatness of the wall. If the flatness of the wall is poor and the error exceeds 5mm, it is recommended to use gypsum to level the wall first. Gypsum has the advantages of fast solidification and strong adhesion, which can effectively improve the flatness of the wall. If the wall flatness is good and the error is within 5mm, you can directly blow putty.

Scraping putty is an important step in the treatment of blank wall. Generally, it is necessary to scrape the putty for 2-3 times, and the interval between each time is 1-2 days, so that the putty can be fully dried. Pay attention to the technique when scraping putty, try to keep it even and flat, and avoid sagging and bumps. After scraping the putty for the last time, use sandpaper to polish the wall to make it smoother and more delicate. Pay even attention when polishing to avoid polishing marks.

After completing the above steps, you can decorate the wall. Common wall decoration materials include latex paint and wallpaper. If you choose latex paint, you should first paint the wall with primer before painting. The primer can enhance the adhesion between the wall and the top coat, and at the same time, it can also play a role in moisture prevention and mildew prevention. Topcoat generally needs to be painted for 2-3 times, and a certain time should be separated between each time. If you choose wallpaper, you should first paint a layer of basement membrane on the wall to prevent the wallpaper from being damp and moldy.

In the process of dealing with the blank wall, we also need to pay attention to the following aspects. The temperature and humidity of the construction environment have great influence on the wall treatment effect. Generally speaking, the construction temperature should be between 5℃ and 35℃, and the relative humidity should be below 85%. If the ambient temperature is too low or the humidity is too high, it will affect the drying speed of putty and latex paint, leading to problems such as cracking and peeling on the wall. In addition, pay attention to safety during construction and wear protective equipment, such as masks and gloves. When using electric tools, we should operate in strict accordance with the operating rules to avoid safety accidents.

The following table compares the advantages and disadvantages of different wall treatment materials:

In a word, it is necessary to properly handle the blank wall according to the correct steps, and at the same time pay attention to the construction environment and safety issues, so as to create a beautiful and durable wall.

　　Many people are asking:

　　On the morning of March 25th, the Information Office of Shenzhen Municipal Government organized a special press conference for this purpose, inviting representatives from Shenzhen Civil Affairs Bureau, Municipal Health and Health Commission, Municipal Transportation Bureau and Municipal Emergency Management Bureau to answer public questions.

　　First of all, give everyone a "reassuring pill"

　　Chang Juping, deputy director of the Shenzhen Municipal Health and Health Commission, said that at present, the epidemic situation in the country is relatively stable, and all areas in Guangdong belong to low-risk areas. During the Qingming period, it is not necessary to provide proof of nucleic acid testing.

　　However, according to the requirements of epidemic prevention and control in COVID-19, the following four categories of personnel are not allowed to participate in the sweeping activities:

　　Persons who have lived abroad (including abroad, Hong Kong and Taiwan) within 14 days;

　　Persons who have lived in high-risk areas in China within 14 days;

　　Close contacts less than 7 days after the release of 14 days of isolation;

　　Persons with acute respiratory symptoms such as fever and cough.

　　At the same time, it is suggested that citizens should remain vigilant during the Qingming holiday, minimize gatherings and do personal protection.

　　Xiong Ying, director of Shenzhen Civil Affairs Bureau, said that due to the suspension of on-site sacrifice sweeping in Qingming last year, it is expected that all kinds of sacrifice sweeping places in Shenzhen will usher in the peak of people gathering this year, and the number of people who sacrifice sweeping may reach more than 700,000. Please abide by the epidemic prevention and control, fire protection, transportation and other relevant regulations, conduct civilized sacrifice sweeping, and advocate home memorial, online sacrifice sweeping, off-peak sacrifice sweeping and smokeless sacrifice sweeping.

　　Special reminder: You must make an appointment to attend the on-site sacrifice in Shenzhen.

　　Appointment method-

　　Online Reservation: "Smart Funeral" Module of "I Shenzhen" APP

　　Telephone appointment:"Shenzhen Civil Affairs Online" official website has issued an appointment number for the city’s cemeteries and columbariums.

　　Since the opening of the appointment on March 20, as of 18: 00 on March 24, the number of people who have made an appointment for the on-site sacrifice has reached 135,800.

　　This year, Shenzhen will continue to carry out green ecological burial. On the morning of March 31, sea burial and tree burial will be held in the whole city. The sea burial place is in Dapeng Bay and the tree burial place is Yoshida Cemetery in Longgang. The public can call 0755-86005056 or 89570408 to inquire about the handling process.

　　Xu Zhongping, deputy director of the Shenzhen Municipal Bureau of Transportation, said that in order to cope with the peak of Qingming travel, Shenzhen opened a special line to repay the blessings and the Qingming Festival in the city funeral home; At the same time, bus companies are required to increase the capacity and encrypt the frequency of more than 100 bus lines passing through key sacrificial sites and tourist attractions at any time depending on the passenger flow, and reserve 45 buses in key areas such as the city funeral parlour and the window of the world for emergency.

　　Yang Jie, deputy director of Shenzhen Emergency Management Bureau, said that during the Qingming period, Shenzhen will strictly grasp forest fire prevention, with 305 important intersections "guarded", 170 important hilltops "watched" and 169 cemeteries "patrolled".

　　According to the weather forecast, it is difficult to see the scene of "rainy in Qingming Festival" in Shenzhen this year, and the situation of forest fire prevention is more severe. Since January, forest fires have occurred in Shenshan, Nanshan and Dapeng New District, most of which are related to unsafe behaviors, including smoking, burning weeds and burning paper money.

go for a spring outing on the Qingming Festival

Don’t step on the roadside wild mushrooms

　　The Shenzhen Municipal Health and Health Commission specially reminded that every spring and summer is the high incidence season of poisonous mushroom poisoning. Most poisonous mushrooms look similar to edible mushrooms and cannot be distinguished with the naked eye.

　　Some identification methods circulated among the people, such as: brightly colored and beautiful-looking mushrooms are poisonous, and those that turn black after frying with silverware and garlic are poisonous …

　　There is no scientific basis.

　　Therefore, during the Qingming period, citizens must not eat any wild mushrooms when they go out for a walk in Shang Huashi.

　　If you eat poisonous mushrooms by mistake, you should immediately call 120 ambulance, cover with blankets and keep samples of poisonous mushrooms to find out the cause of poisoning.

At present, there are 5 confirmed cases in the hospital in the city, all of which are general cases, and 6 asymptomatic infected people are under medical observation.

　　Generally speaking, the epidemic situation in the city is generally stable, with no new imported cases, no new local cases and no new asymptomatic local infected persons for 60 consecutive days.

　　Shenzhen no longer implemented the "14+7" policy for immigrants, but instead implemented a 14-day centralized isolation medical observation measure. During the isolation period, nucleic acids were detected four times on the first, fourth, seventh and fourteenth days.

　　After 14 days of isolation, if the nucleic acid test result is negative, the isolation observation can be lifted and the free flow is allowed. Measures such as extending the time limit, home isolation, home health management and community health management shall not be taken for those who have been released from isolation.

　　Among them, the entry personnel whose destination is Shenzhen and meets the conditions of home isolation, and whose nucleic acid test is negative, can voluntarily apply for "7+7" isolation medical observation measures, that is, centralized isolation observation for 7 days+home isolation observation for 7 days.

　　As of March 24th, Shenzhen has vaccinated 2.09 million doses of COVID-19 vaccine and 1.44 million people. The next step will be to vaccinate all kinds of people with Covid-19 vaccine in stages according to the unified arrangements of the state and the province.

Yesterday morning, Chen Jining, secretary of the Municipal Party Committee, combined with the implementation of the "service package" system of key enterprises, went to China Shipbuilding Group Co., Ltd. to visit and investigate related enterprises. Chen Jining said that Shanghai’s modernization and high-quality development cannot be separated from the strategic support of central enterprises. We should thoroughly study and implement the spirit of the important speeches made by the 20th Party Congress and the General Secretary of the Supreme Leader on his visit to Shanghai, seize the opportunity of intelligent, green and integrated development, further strengthen the leading function of high-end industries, vigorously promote the construction of modern industrial systems, fully support the central enterprises to play a leading role, accelerate the improvement of innovation systems, enhance innovation capabilities, stimulate innovation vitality, promote the deep integration of industrial chains in innovation chain, and work together to build world-class industrial clusters to better serve major strategic tasks of the country.

China Shipping Group, headquartered in Shanghai, has taken solid steps towards the goal of building a world-class shipping group since its establishment more than three years ago. At present, the main shipbuilding indicators such as shipbuilding completion, new orders received and hand-held orders rank first in the world, and it has entered the world advanced ranks in the fields of super-large LNG carriers, super-large container ships and dual-fuel marine power equipment, and the core competitiveness of the shipbuilding industry has been continuously enhanced. Chen Jining and his party first came to Shanghai Waigaoqiao Shipbuilding Co., Ltd. and boarded the first domestic large-scale cruise ship "Aida Modu" to see the planning and layout of relevant functional areas, listen to the introduction of cruise ship design, research and development, construction, trial operation and cruise ship delivery and operation plan, and make a concrete understanding of key core technology breakthroughs, innovation in production organization forms, and application of green environmental protection technologies.

"Alone Army" is a work supported by major literary and artistic projects in Sichuan Province. It is based on a real history. In February 1935, in order to cooperate with the strategic shift of the main force of the Central Red Army, the newly established guerrilla column in southern Sichuan undertook the task of harassing and containing some of the main forces of the enemy. With the support of the people of Sichuan, Yunnan and Guizhou, the guerrilla column in southern Sichuan fought to the death with the Kuomintang army whose military strength was dozens of times that of its own, fighting alone, and most of the Red Army soldiers died heroically. The film is a creative, innovative and sincere film with distinctive theme, lofty conception, rigorous structure and touching story.

Some battles on the way to the Long March, such as the bloody Xiangjiang River, crossing the Jinsha River skillfully, crossing the Dadu River forcibly, flying over the Luding Bridge, crossing the snowy mountains, and capturing Lazikou, as well as some major historical events, such as the Zunyi Conference, have been reflected and presented in movies in the past. The film "Alone Army" tells the story of the guerrilla column of the Red Army in southern Sichuan, which is an affectionate creation and theme expansion of the Long March film, and even fills a gap in the Long March film. The creative team led by the relevant leaders of Xingwen County, Yibin City, Sichuan Province and Liu Zhihuan, the chief producer of the film, dug deep into history, studied history, put a historical fact that was almost forgotten on the screen and presented it artistically and aesthetically, thus continuing the red culture in the film language.

Yang hu, the director of Alone, is good at shooting military and war movies. After watching this movie, we can see his unremitting efforts and active exploration. In order to restore the real historical scenes, especially the war scenes, "Alone Army" filmed the blocking war, siege war, sports war, etc., which is vivid, dynamic and layered, and can meet the requirements of the current audience, especially the young audience, for the audiovisual quality of cinema films. For such military and war movies, the film’s creative team is adept at grasping the whole history, highlighting the truth of the details, attracting the audience into the cinema, and effectively accepting and spreading the spirit, thoughts, emotions, especially lofty beliefs contained in the red movies.

The plot of "Alone Army" is tortuous, and the rhythm is fast. However, in limited space and time, the main creator also strives to create personalized and full images of Red Army commanders and soldiers, which forms great tension in the setting of character relations and produces strong dramatic conflicts, making the connotation of the film richer and deeper. "Being alone is not alone", because the spirit of being alone is immortal. "Alone" expresses the soldiers’ precious faith and lofty realm through their arduous battles and life course of dying, and naturally expresses this expression in the development of plot and scene, which brings shock to the audience and realizes maximum empathy, resonance and resonance.
