Where is a tree house in China?

Some ethnic minorities in Yunnan have a tradition of building houses, such as Dulong. In the past, the tree house was a unique living form of the Dulong people. They built their houses on thick tree trunks and decorated them with rattan and bamboo so that they could live there and resist wild animals and bandits. With the progress of society, there are fewer and fewer tree houses, and now they are only for sightseeing.
