From which dynasty did China take off his shoes?

By the time of the Tang Dynasty, China was still living in a secluded place, and he had to take off his shoes. At that time, there were no beds and chairs, only a low table with tatami on the ground and tatami on the ground. Everything was kneeling on the ground until the Tang and Five Dynasties, when the country began to popularize bed chairs, and until the Song Dynasty. At that time, when you enter the room, you can see the sunken porch or the all-wood house. When the Mongols invaded in the Yuan Dynasty, great changes began to take place in the architecture of China, and stone houses began to appear.
