One and only: Xue Yifan’s graduation photo is different from others because the 22-year-old is the only one in her department to graduate in 2014. The paleontology student of Peking University shared her picture on her social media account, where hundreds of thousands of students commented on it and reposted it. They joked about Xue being lonely, as she was the first and last in her class. According to Lu Xiaodong, vise dean of Yuanpei College, Peking University, paleontology is the only major in China that nurtures only one student each year. XINHUA
