China's hierarchy of hospitality.

Before the Han Dynasty, people in China lived on the floor, so the center of life must be around the sleeping place, and all the guests are around the host's sleeping place. Over time, the hierarchical concept of China people's hospitality has been formed. Before the Qing Dynasty, even in the early years of the Republic of China, the highest hospitality of China people was always on the bed or on the kang. The main function of the couch and arhat bed is not to sleep, but to entertain guests.
