You may have already forgotten the days when you had to learn how to use chopsticks. Every Chinese kid struggles with them for some time. They come with their own special rules and traditions.

Playing with chopsticks is seen as bad manners, just as making noise with forks and knives in a Western country would be rude.

There are also some superstitions(迷信)related to chopsticks. For example，some people believe that chopsticks should not be left standing upright in a bowl. It looks like the incense(香) that Chinese use to honor the dead.

You should not tap chopsticks on the edge of the bowl either, as beggars do this to ask for food. Parents may get mad if children do this as they don't want their children to be as poor as beggars in the future.

Apart from being tableware, chopsticks can also be a great gift. Newlyweds(新婚夫妇) sometimes receive chopsticks as a wedding gift. Skilled craftsmen paint beautiful images on chopsticks to make them look like fine artworks.

If you go abroad, first you are expected to bring your passports. (two), you should make an effort to know some customs. For example, when you greet people in Korea, you should bow. You'd better take off your shoes you drop by someone's home in Japan. You can't knock your empty bowl at dinner in China. In France, you can greet people by kissing. In Washington D. C., the capital of the USA, you (suppose) to value time, especially in their busy season, or your friends may get mad.

The table (manner) are different in different countries, too. Once I visited the eastern coast of the USA as exchange student. Though the host family went out of their way (make) me feel at home and the granddaughter tried her best to make me (relax), I didn't get used to the basic manners there. I was born in a northern city all. I think everyone behaved well except me. I ate lunch with my two elbows on the table. I didn't clean off the chalk on the blackboard at noon. I still feel nervous these days.

So I think a teenage student should get some (suggest) before going abroad. The good manners are worth (remember) gradually.
