Does anyone have information about yurts?

A yurt is a type of house where Mongolian herdsmen live. It is easy to build and relocate, and is suitable for animal husbandry production and nomadic life. In ancient times, the yurt was called Qionglu, "felt bag" or "felt tent". According to "Hei Tarshi Lue": "There are two types of domes: the one made in Yanjing is made of willow wood, just like the southern Fusi, which can be rolled up and stretched out. There is a door in front, like an umbrella frame on the top, with an opening on the top, which is called a skylight. They all use felt as clothing and can be carried on horseback. The grassland is made of willow wood to form a hard circle, and the path is fixed with felt tarts. Domes or felt tents were gradually replaced by yurts. The yurt has a round pointed roof and is covered with one to two layers of thick felt on and around the top. Ordinary yurts have a top height of 10-15 feet, a wall about 5 feet high, and the door opens to the south or southeast. The four major structures in the package are: Hana (that is, the Mongolian wall bracket), skylight ("Tao Nao" in Mongolian), rafters and doors. The size of the yurt is determined by the number of hanas, usually divided into 4, 6, 8, 10 and 12 hanas. The 12-hana yurt is rare in grasslands and can cover an area of ??more than 60 square meters. Nowadays, the nomadic life is gradually replaced by settlement. The wealthy herdsmen on the grasslands have built brick houses, and there are fewer and fewer yurts.
