What is the felt bag like?

Also known as the top floor or felt tent, it is a tent for ethnic minorities living in northern China in ancient times. Felt bag is the predecessor of Mongolian yurt, which is generally round. Generally, net walls and umbrella-shaped roofs are made of wood strips, covered with felt, and then tied with ropes. There is a circular skylight in the center of the top of the felt bag, which is convenient to assemble and disassemble and suitable for nomadic life.
