Before 1952, Peking University and yenching university merged into the new Peking University, the west gate of Peking University was the main entrance of yenching university. There are two stone lions on both sides of the school gate, which were donated by yenching university alumni, so it is also called the Alumni Gate.
There are also a pair of mighty stone lions on the left and right sides of the school gate, with curly hair and bright eyes, which makes the west school gate more solemn.
