Introduction to thatched shed: There are more than twenty buildings imitating primitive people at the Xinle site. Each building imitates the customs, habits and characteristics of primitive ancestors, and simulates various life and production scenes. These huts are all semi-burrow-style living pits. The primitive ancients at this time lived one or two meters underground, building shacks made of thatch branches above. A small group or a large family lived in a semi-burrow-style shack. Life, this kind of semi-cave shack can not only block rain, snow, wind and cold, but also prevent attacks by large beasts.
