Introduction to Zishu Hall: Zishu Hall was originally located in Shangzhang Village, Mohuan Township, Longyou County. It was built in the late Daoguang period of the Qing Dynasty and was funded by Zhang Shitang, the 18th generation grandson of the Zhang family. The building area is 465 square meters. The gatehouse has a brick-carved imitation wood structure, four-column double-eaves archway style, with unique and spectacular heights. The building has three entrances and three bays. The first and second entrances are halls, which are used for receiving guests and holding large-scale celebrations. The third entrance is used to enshrine ancestral tablets and is a place for families to renew their incense. There are two small patios at the junction of the two entrances of the building, made of stone railings and fences, with a unique design. The corbel is one meter high, making it the largest corbel ever found in the county. It can be said that the desserts are made in the mansions of the wealthy Longyou merchant gangs.
