A few quick tips if you are coming to china first time and coming to zhuhai specifically,
1) Make sure you have your Visa . i have seen people often jumping in to plane thinking they need no visa. Check this china govt website for visa info (http://www.fmprc.gov.cn/eng/ljzg/3647/3648/)

2)You can reach zhuhai through 1) Macau , where there are three border points. In case you need more details drop me a message. 2) Honkong, directly from HK airport via the ferry in which case you dont need to cross HK immigration . The other is to go to HK-Macau ferry terminal in island or HK- China ferry terminal and take a ferry from there . It will take you about 1 hour.

3)In case you dont know mandarin or cantonese, i suggest you carry chinese address copies of the place you have to go when you enter china. You can show it to any taxi driver in china and normally they know the place. Taxi's are not expensive but try not to take private taxis's. The taxis in zhuhai are normally in green or blue colour.

4)for adventurous men a piece of advise is that please donot venture out to nightclubs alone and get into argument with locals. Though normally people are very friendly to foreigners here you can cause serious harm to you if you think you are a cowboy in texas.

If you need any further info , do drop me a message.
