Introduction to the former residence of the master: The former residence of Master Yun Da was built in the 1920s in the Chinese architectural style, with two floors and an outer corridor, totaling 200 square meters. During the Anti-Japanese War, Yunda was bombed many times by Japanese planes, but the small building survived. In 2002, the small building was renovated according to its original style. Two principals, the mathematician Xiong Qinglai and the writer Li Guangtian, once lived and worked here.
