The most famous one-Baota Lake, the Unnamed Lake Library in Tuboyata (99% can't get in, unless you borrow a card from your classmates, but generally no one lends it to outsiders, which is forbidden by the school), and then the West Gate Triangle of the Centennial Lecture Hall (although it is quite famous), the Jingyuan lawn and surrounding buildings, and a monument to revitalize China. It doesn't have to cost money to enter the school, and sometimes the access control is very strict. You can't get in if you show your campus card. Eating costs money, and most canteens don't accept cash. It would be better if I could borrow a meal card from my classmates. Otherwise, you can go to the second floor of the art park, and the cash consumption is not expensive, just a few tens of dollars for two or three people and less than one hundred. Souvenirs are abundant, which are available in many shops in the triangle and are also sold by comprehensive service organizations. The price is unknown.
