Annoyances

The Chinese habit of staring, especially in smaller towns and rural areas, can be a little annoying. However, the intent is rarely hostile. Staring was common even in Beijing until the 1990s, and although it is rare in cities today, it helps to remember that China was closed to foreign nationals until the early 1980s.
Another annoyance that visitors face in smaller towns is the constant calls of "Hellooo!"or laowai (foreigner). It is best either ignore them or smile, as saying hello often result in bursts of laughter. In large cities, people strike up conversation to practice their English. Sometimes, art students try and coerce you into visiting over-priced art galleries, which you should firmly decline to do.

Smoking and Alcohol
As the world's largest producer and consumer of cigarettes (Xiangyan ), China is a smoker's paradise. Despite the appearance of no-smoking zones and rudimentary anti-smoking campaigns, town and cities remain shrouded in a haze of cigarette smoke. Smoking is now banned on domestic flights and in train carriages (except in the corridors), but rural buses remain fumigated. There are usually non-smoking floors in four nd five-star hotels, but don't expect any at cheaper hotels. Smoking during meals is totally acceptable, especially if there are other smokers present. The Chinese are very generous when it comes to offering cigarettes, so remember to be equally generous in return. They also enjoy drinking alcohol, and there is no taboo against moderate intoxication. The usual accompaniment during a meal is beer (pijiu), Or white spirit (baijiu). People reraly drink wine (putaojiu), although it is available at restaurants serving western cuisine. If someone raises a toast to you (ganbei!), it is good form to toast the person back at a later stage.
