商务礼仪—— In the Home
1) The Right Time to Arrive
When invited to luncheon, dinner, or supper, it is very impolite to arrive late, as it is usually planned to have the meal at the exact hour given in the invitation.
2) In arrival
When you arrive, the hostess or some member of the family will probably meet you at the door and take your coat and hat. In the winter time you should dress more lightly than usually, as you may expect the rooms to be warmer than in most Chinese homes.
3) In a few minutes the hostess will ask her guests to come in to dinner. She may or may not ask each gentleman to take a lady in. If she does, the lady will take the gentleman's arm as they walk into the dinning room. If she does not, the ladies will go in first, followed by the gentlemen. The hostess will either point out their seats to the guests as they come in or have a place card at each place with the guests name on it.
4) How Long to Stay
After the meal is over, it is not polite to leave for at least half an hour, lest you seem to have come only for the meal. An evening dinner invitation usually implies that you stay for the whole evening. The hostess often plans some after-dinner entertainment.
5) What to Say on Leaving
When leaving any kind of a party, a guest always expresses his appreciation to the hostess. Some such words as these are appropriate. "Thank you so much. I've had a delight evening."
