In Qin and Han Dynasties, tables and chairs were invented, which liberated people from kneeling, and developed from eating on the floor to sitting on the table. During the Sui, Tang and Five Dynasties, there was no floor banquet, and food cases were no longer attended. Most of them are used as offerings, and the short legs of the case are gradually abolished and replaced by short tables and chairs, which completely changes the unsanitary phenomenon of taking off shoes after drinking. Implement a separate meal system. Your family implements the system of one person, one table and one chair, and food is placed on each table. This system of separate meals meets the requirements of food hygiene. In the Ming dynasty, with the appearance of square tables, the dinner system began to appear, and there were "seats" at the banquet. In the Qing Dynasty, there appeared a group table, that is, a round table, also known as a group round table. Traditional banquets in China originated in the summer, flourished in the Sui and Tang Dynasties, flourished in the Ming and Qing Dynasties and flowed in the Republic of China. They always change steadily with the change of dynasties, from simple to complex, and from complex to simple.
