When did kneeling start and end?

Kneeling should be the sitting posture of the ruling class of businessmen who are still ghosts, and it has become a ceremony to worship ancestors, worship gods and entertain guests.

At the end of the Eastern Han Dynasty, the Hu bed (chair without backrest) in the north was introduced into the Central Plains. It was widely used in Wei, Jin, Southern and Northern Dynasties, but it belongs to high-grade furniture, and only the male host and distinguished guests in the family are eligible to enjoy it, so many people kneel.

From the reign of Emperor Xuanzong of the Tang Dynasty, chairs with backs appeared, which became common furniture in daily life, and people kneeling basically disappeared.

Of course, the radical change of lifestyle has not changed the long-standing habit of bowing, and bowing remains as a fixed etiquette.
