Personal relationships ("guanxi" in Chinese) in business are critical. "Guanxi"  is deeply rooted in Chinese culture and is basically "a tool to get business" and "a way of getting things done." It often takes months, perhaps even a year or more, to establish “guanxi”.

Meeting people: Upon the initial greeting of meeting someone for the first time, short handshakes are usual on first meeting 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).

Meals: At a formal meal or banquet, you will be expected to at least sample every dish. 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.

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 "mao tais" (a traditional Chinese drink).

Tipping is officially forbidden, and most hotels and restaurants impose a service charge in lieu of tips. However, the practice of tipping (in private) has become more widespread in recent years because of the influx of Westerners.

The politest 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. And remember, the soup comes last in a traditional Chinese meal.
