Introduction to Wu Jianhua's Residence: Wu Jianhua's Residence is a private residence in the mid-Ming Dynasty, adjacent to Si Jiandi. It is a brick and wood structure building with small blue tiles and a horse head wall. According to research, it was originally built with three floors, but later in the Ming and Qing Dynasties it was changed to two floors. The shuttle columns, moon beams, brackets, reed walls and board decoration all have obvious Ming Dynasty architectural styles. The window partitions are similar to Fang Wentai's house. The small hall pool was originally built on three floors to meet the lighting needs of the ground floor, so the patio is relatively spacious.
