Introduction to ancient dwellings: Langshi Village is a unique ancient large-scale residential building in southwestern Hunan. There are 88 ancient dwellings in existence, with a total area of 10,880 square meters, of which 55 are fully preserved, all of which are brick and wood structures. There are blue brick walls at both ends of the house, and a wooden house with wooden pillars and frames in the middle. The blue bricks of some houses are inscribed with dates such as Kangxi, Qianlong, Jiaqing, and Guangxu; some windows, doors, columns, niches, and beams have many reliefs and hollow flower carvings, which are lifelike and extremely exquisite.
