First, don't serve wine after the guests.
This, in fact, also reflects a person's accomplishment. Many times, we have to ask ourselves to wait before the guests at the wine table, so as to better let others feel your mind. If you are late, it is obviously a sign of great disrespect to the guests.
Second, the dishes on the table must be odd.
In this case, it may be that the customs of each place are different. In our place, the dishes on the table must be odd. If it's not enough, add vegetables. I don't know the specific reason, but this has always been a requirement.
Third, you must wait for the guests to move chopsticks first before you can move chopsticks.
This is also a courtesy, because you entertain guests, so you must let them eat first before you can eat. This also shows your respect for the guests.
To sum up, we should know that there are many traditional ways to entertain guests in China, and we should follow some. This kind of hospitality makes our behavior more polite and makes others feel more comfortable.
