Why do you call dinner a banquet?

The ancients sat on the floor, and "banquets" and "seats" all sat on the floor. The annotation of Ji Yan in Zhou Li Spring Palace Temple says: "Spread the floor and say banquet, learn from it.". It means: what is spread on the ground is called "banquet" and what is spread on "banquet" is called "mat". Therefore, the word "banquet" began to become the floorboard of seating. In the Book of Songs, there is a saying of "banquet", and the word "banquet" means wine. The Book of Rites, which describes the Warring States, Qin and Han Dynasties, said: "Set up a banquet, Chen Zunzu, and set up beans." At this time, the banquet also contains the meaning of a grand and formal banquet. In this sense, the word "banquet" was used, and later it specifically referred to banquet.
