The forest pit is not in vain. It has the most complete mountain dwellings preserved in Nanxi River. They all have a history of more than 100 years, and the oldest wooden house is over 200 years old. The wooden house with exquisite shape is hidden in the green mountains and waters, simple and natural. Folk houses built in accordance with mountains are scattered and unified in harmony. Small and medium-sized bridges and flowing houses in villages, smoke curling and white clouds sometimes dazzling, make people wonder where they are.
