Introduction to the Cheng Clan Ancestral Hall: Also known as the "Dunmu" Hall, it is backed by Shishan Mountain and faces the Yao River. It was built in the middle of the Ming Dynasty and was renovated during the Daoguang Period of the Qing Dynasty. Its architectural style is different from other ancestral halls. The brick carvings, stone carvings and wood carvings in the building are rich in themes, exquisite, clear, layered and lifelike, showing the superb artistic talents of the carving craftsmen. During the Anti-Japanese War, Comrade Chen Yi held an anti-Japanese mobilization meeting in the ancestral hall.
