A person’s graduation photo Peking University paleontology major ushered in ＂6 generations of single biography＂

　　Graduates enter the Chiudaba Gymnasium on a department-by-department basis, while Ernest & Young Rui is only one person. During his four years as an undergraduate, he has become accustomed to such a scene.

　　The college leaders plucked the ears for Ernest & Young Rui, and the end of this session meant that he had officially graduated from Peking University with a happy expression on his face.

　　While waiting in line to take graduation photos, students from the school joked with him: "For a graduation ceremony alone, you are popular, and this bouquet of flowers is for you."

　　He was preparing to leave the school around July 10, and was going to pack his things in the dormitory into cardboard boxes. Because he was about to stay on campus for graduate school, his luggage could also be stored in the dormitory during the holidays.

　　After the graduation ceremony, Ernest & Young Rui went to meet their graduate advisor and left a selfie while passing by Peking University Library. He said that in the next five years, it will be his most frequent place.

　　Holding up his phone, looking up, looking up, smiling, this summer, on the banks of Weiming Lake, under the Boya Tower, in front of the library, and at the entrance of Yuanpei College, Ernest & Young Rui, a paleontology major at Peking University, completed one "graduation photo after another" in a standard selfie pose.

　　Like his senior sister Xue Yifan, who graduated two years ago, these photos also made Ernest & Young angry. Four years ago, when he was admitted to Yanyuan with the top 20 results in Guizhou Province, he did not expect that the future experience would be so special.

　　During high school, this boy from Guiyang was interested in physics, biology, Chinese, and history. After the college entrance examination, it was difficult to choose a professional direction, so he chose Yuanpei College as an experimental field for thorough training.

　　In the first two years of college, like other students in the college, he took a large number of general education courses. After studying courses such as "Paleontology", his interest in this direction gradually became stronger, so he chose to major in paleontology in his junior year and became the "only seedling" of this major. Since Peking University established this direction in 2008, only six graduates have graduated in total, which is known as "six generations of single biography".

　　一个人的专业，并非一个人的课堂。因为古生物学主要以化石为研究材料，小安选修了多门生物学、地质地层方面的课程，他经常同地球与空间科学学院和生命科学学院的学生同堂听课，讨论专业问题。他的跨学科导师团队也不简单，城市与环境学院的周力平和地球与空间科学学院的黄宝琦两位老师都曾指导他写论文。

　　生活中，与元培学院的同学为伍，学习上，则跟外院同学结伴，在别人看来似乎有些孤单割裂之感，小安却习以为常，“这让我在两边都能找到一定的归属感。”

　　在贵阳郊区长大的安永睿，从小就对山川、河流、大地等地质地貌感兴趣。对于世界的探索之心，在十几岁时便已萌发。初中时，小安经常独自出游，选择假期的一天，一早出发，晚上归家。踏遍农田，探访山林，走走城区，他总在寻找不一样的风景，几年下来，他的足迹已遍及贵阳周边十几个县市的200多个乡镇。

　　小安是个典型的南方男孩儿，外表斯文安静，说话语速较慢，笑起来还有些害羞。或许是为了弥补在专业上的孤单，他在社团活动中寻找自己的精彩。大二，他参与创建北大徒步爱好者协会，经常和大家一起去香山、妙峰山等地徒步，用双脚走上二三十公里，对他而言小菜一碟，他的最高纪录是在贵阳老家花一天时间走了80多公里。大四，他还加入北大最出名的社团山鹰社，去过雾灵山、百花山、海坨山等地拉练。小安也在提升自己的文艺细胞，他会唱京剧、昆曲、越剧和泉州南音。不过，大学四年，没能找到属于自己的坐在自行车后座的女孩，让他直呼“相当遗憾”。

　　如今，小安已保送北大城市与环境学院攻读直博学位，研究神秘的第四纪地质学方向，继续探寻古生物界的奥秘。他期待着，如自己喜欢的《原乡人》所唱的那般，“我走过丛林山岗，也走过白雪茫茫，看到了山川的风貌，也听到了大地在成长。”
