Built in the Ming Dynasty, the 30-meter-high Baosu Hall stands to the west of Xiuye Bridge, West Zhongshan Road in Songjiang District. It was once the location of a big ancient residence but now only Baosu Hall remains there. The board “Baosu Hall” once hung in the front of the hall is not in the existence today. According to the legend it was the residence of Xu Jiade, the head of Pinghu County in the Qing Dynasty, and so it is also named the Xu’s Hall. The grand hall is richly ornamented.
