Taking food from the centre of the table and directly putting it into your mouth is considered impolite. Instead, before you eat it, put it into your bowl first.
At the end of each course, leave bits of food on your plate to show that you were satisfied with your meal. Not doing so would embarrass the host and make them assume you did not receive enough food.
If fish is served during your meal, notice that the head of the fish will be facing the guest of honor. This part of the fish is seen as a delicacy to the Chinese. If you find yourself as the guest of honor, do not de-bone the fish yourself as it would be seen as bad table manners. Instead, wait for the server or your host to de-bone it for you.
Instead of the common paper napkin, traditional Chinese restaurants distribute hot towels before and after the meal. It is seen as appropriate to use it for your hands and face.
If you are not using your chopsticks, either lay them out in front of you or place them on the rest provided.
Never point at someone or something with your chopsticks.
Laying your chopsticks across each other is considered bad luck.
Do not position your chopsticks upright in your rice bowl, this is done at funerals when a bowl of rice within which are standing chopsticks is placed at the altar.
If you find yourself at a business meeting in Hong Kong, tea will most likely be served to you. However, do not take the first sip as the Chinese wait for the senior host to do so. This shows that the meeting is going well.
At a Chinese restaurant, the cultural sign language for requesting more tea would be to open the lid of the teapot or place the lid upside down on the table.
Normally at a formal dinner, wait until you’re told where to sit as the seating plan is contingent on hierarchy and seniority. The seat for the guest of honor would be at the center facing the entrance of the venue, while the host sits across the guest of honor with their back facing the entrance door. As for the rest of the party, the more important people sit close to the guest while the rest sit further away.
