Introduction to Tianchejia Ancient Cliff Dwelling: Located in a long and narrow cave on the mountainside of Danxia Peak, it is one of the best-preserved cultural attractions among the dozen existing ancient cliff dwellings in Wuyi Mountain. According to legend, mountain people lived here in caves during the Song Dynasty. During the Xianfeng period of the Qing Dynasty, the Taiping Army entered Chong'an, and this place became one of the refuges for local wealthy people.
