On arrival one should first introduce oneself, or let the master of the banquet do the introduction if unknown to others, and then take a seat in accordance with the master of the banquet’s arrangement.
The seating arrangement is probably the most important part of Chinese dining etiquette.
If the guest of honor or most senior member is not seated, other people are not allowed to be seated. If he hasn’t eaten, others should not begin to eat. When making toasts, the first toast is made from the seat of honor and continuing down the order of prominence.
