In winter and winter vacation, we enter Peking University, the highest University in China with a strong sense of history. Campus has a long history, there are many ancient buildings, full of details, unknown Lake (can skate in winter), Boyata reflects each other, surrounded by green trees, the environment is very beautiful. Here I feel the artistic conception of "laughing and talking about Hongru, contacting without Baiding". The south side is dominated by various teaching buildings on the campus of Peking University. The famous Centennial lecture hall of Peking University, Guanghua Building and other buildings are also here. The tour route is to walk in from the southeast gate (because only this door is open to tourists). First, we watch the buildings on the South side, then go to the North side, enjoy the ancient buildings and landscape lakes, and finally leave from the West gate. There are four-character plaques of Peking University in Ximen. They are usually taken here for commemoration. Another Huabiao in Peking University was transferred from Yuanmingyuan. The Southeast Gate opens from 8:30 a.m. to 11:30 p.m. and from 14:00 p.m. to 17:00 p.m. and needs to be registered with an ID card or a registered permanent residence book.
