Nanjing University is located in the ancient capital of Jinling. It is a century-old famous school. Its predecessor was the Sanjiang Normal School founded in 1902. At present, there are two campuses, Gulou and Xianlin. The Gulou Campus, where ancient buildings are concentrated, is the main campus for tourists. A stroll through the lush campus will call to mind campus life. The North Building of the Gulou Campus is a Nanjing University landmark. This Western-style brick and wood structure has been used since the Warlord Era. Mr. Yu Guangzhong once said that “Ivy climbed the North Building”, and now it is still the same, and the red star on the roof is particularly eye-catching.
