Meeting people:
Never arrive late. Chinese are very punctual. Upon meeting someone for the first time, short handshakes are usual followed by the Chinese greeting of "ni hao?" which translates to "How are you?" Rather than try to remember the full, two-or-three syllable Chinese name, listen for the first one (the family name).
Bring lots of business cards when visiting China. Do not be afraid to offer your business card. Chinese people like to exchange business cards. Chinese names are traditionally written with the last name first and other names second. When accepting a business card, accept it with two hands, holding the card with fingers with both hands. This is a sign of respect and hope for a long lasting relationship.
Traditionally, conversations in China, even business conversations, start out with innocuous topic, to set a mood of friendliness. Eventually, the small talk might become quite direct, which is not meant to be offensive. It is quite common on short acquaintance to be asked about personal matters, including questions about your family status.
Giving Gifts:
It will be appropriate to bring small gifts to your host(s) to express your appreciation of their assistance. You need to avoid certain gift items such as the "clock". The words "give you a clock" sound similar to "attending your funeral." Umbrella can implicate "departed or separated;" knives or other objects with sharp blades can implicate "cutting the relationship."
Mealtimes:
At a formal meal or banquet, dishes will be served on a big round table rotating table to be shared by everyone. You are not obliged to eat all of the meal given. However, if you finish a dish, chances are you will be given a refill. Try to leave some food on the public plates. If a plate is cleaned up, chances are the host will order more food.
At meals and receptions the host will give a toast. Often a choice of drinks, both alcoholic and non-alcoholic will be offered. Beware the Chinese toast "gan bei", which roughly means "bottoms up", especially if you are drinking "bai jiu" (a strong liquor).
If you are not used to alcohol, the most polite way out is to say "sui yi," which, roughly, means "cheers, but I will only drink a little." Be prepared to offer a toast to your host or the most senior member, and remember the soup comes last in a traditional Chinese meal. If you are the guest, be prepared to leave first after the meals. The Chinese host will leave after the guests.
In the Streets:
Chinese people in Beijing and other big cities have become accustomed to foreigners, but if you get off the beaten track in the city or elsewhere, you will be bound to attract attention. It is only curiosity, and you will generally find people helpful. However, if something doesn't quite happen as you imagined, you should stay calm and polite. As a rule, complaining or shouting only results in mutual loss of face and a deterioration of the situation.
Dress:
China is a conservative society. Unless you want to attract attention, dress conservatively. However, it is not necessary to dress formally, except for business meetings and receptions.
