There is an ancient residential building community in Longhua Ancient Town, Pingshan County, Sichuan Province. It has a distinct Ming and Qing Dynasties and traditional Lingnan architecture. There are both the characteristics of the Hakka enclosure culture and the unique style of Chinese business architecture. The architectural pattern contains the mysterious concept of Feng Shui. The ancient buildings are all "masonry half-wall, blue brick to the dong", and the village is in the middle of the road. The ancient town is surrounded by mountains and waters and is built at the intersection of Dalongxi and Xiaolongxi under the Laojun Mountain. The ancient town's small street is built on the mountain, and the houses are scattered. The stone steps connect the upper and lower streets into a ring. The streets are all paved with bluestone slabs, and the all-wood structure of the neighborhood is well preserved.
