At family gatherings, seats are usually sorted according to seniority and age. No matter who treats you, the person with the highest qualifications or the oldest usually sits in the innermost position facing the door, and then ranks in the order of qualifications or age.
In the party of friends or classmates, the person who pays the bill usually sits in the position facing the door, that is, the main seat. Others are arranged by age, but because friends are more casual, they rarely care about these.
At a formal banquet, the seating arrangement is more detailed. The chief is generally at the position opposite the main entrance, and the main guard is at the side of the main entrance, which corresponds to each other. On both sides of the main guard, there are guests of honor and deputy guests, and the deputy guard is located opposite to the main guard. If there are multiple tables, they should be arranged from the main table according to the above principles, and the other tables should be arranged in the same way as the main table.
Generally speaking, the arrangement of banquet seats should not only respect traditional etiquette, but also be flexibly adjusted according to the actual situation and the identity of the participants.
