WritingSample 1Dining Customs in ChinaEvery country has its own peculiar dining customs. The Chinese feel that the first rule of being a courteous guest is to be modest. When a person is invited to dinner, he will decline first because he is afraid it will give the host and hostess a lot of trouble preparing for it. As the host keeps on inviting him, he’ll then accept it. Usually the guest will bring some gifts to the host, such as fruit, flowers and wine. The host will immediately protest his doing so by saying, “You shouldn’t have bought the gifts. You are too polite and generous!”When the guest sits down and starts chatting, the host offers something such as tea, c andy, and fruit. The guest always says, “No, no, please don’t bother, I am not thirsty,” or “I’ll help myself to them.”When the dinner is ready, the guests are invited to sit down first. They sit in the chairs that are facing the south, which are considered to be honored seats. After everybody is seated, the host asks the guests to start eating first because they will not eat before the host says so. The guests often avoid being eager to eat out of politeness. They usually don’t empty the dishes to show th at the host has prepared more food than enough out of their hospitality. On the other hand, the host and hostess usually prepare a lot of food to feed their guests.When the dinner is over, guests will offer to help with the cleaning, but of course, the host and hostess will not let them do so. Instead, they will ask the guests to watch TV, drink tea, and sometimes to join a card game or Mahjong game. After some time, the guests will leave, and it is customary for the host to see the guests off. The host tries to see them off to the farthest feasible point while the guests try to discourage them from doing so. The guests will usually invite the host to their home in order to return the favor.Sample 2Dining Customs in ChinaIf you are a guest in China and you’re going to have dinner with the Chinese, you should learn many things about the dining customs in China.Before the dinner begins, the guests and the host all sit at the table. Usually the hostess is busy preparing dishes and the host will chat with the guests. The dinner will begin when everybody is present.When the dinner begins, the host says to the guests, “Please help yourselves!” the guests usually say, “Ok! Ok!” The host starts the dinner first and the others follow. The host or hostess will bring food to the bowls of their guests to encourage them to eat as much as they can. The guests will say “No, no, you don’t have to bother” or “I’ll help myself” at the beginning and will let the host or hostess do so later on. At a Chinese table a guest should not eat too quickly to finish eating very soon. The Chinese like to talk with each other during the dinner. If someone eats without speaking to anyone else, he is considered unfriendly or impolite. So the atmosphere at the dinner table is always pleasantly noisy.At the end of the dinner, if someone wants to leave the table, he should apologize to others for not being able to accompany them to the end and at the same time ask them to eat slowly.These are a few dinning customs in China.。
