Introduction to the brick-carved gatehouse: Although Hu Xueyan lives in Hangzhou, his ancestral home is Jixi, Anhui, so most of the Hu family's mansions have Hui-style architecture. People often say that there are three sculptures that can be seen in Hu Xueyan's former residence: the first is the emblem sculpture on the roof, the second is the wood sculpture in the house, and the third is the brick sculpture in the corridor. The carvings that can be seen everywhere are exquisite in craftsmanship and have long meanings. They can be said to be the most culturally charming part of the former residence.
