See main article: Chengyang, Guangxi. north of Sanjiang, toward Hunan province, lies the area of Dong people, Chengyang (程阳), which is a popular destination for backpacker tourism. The area comprises eight traditional Dong minority villages. The houses are all made of wood. Inside the villages you will find traditional drum towers, which were used to announce important things or simply to perform plays to entertain the villagers. Crossing the river is the best preserved Wind and Rain Bridge (程阳风雨桥, chéng yáng fēng yǔ qiáo) which has five parts. The bridge dates to 1912 and is for many people the main reason to visit the village.
North of Chengyang lies the tiny village of Linxia which is interesting because of the local market, but there are no places to stay in Linxia.
