Reservations there  can be conveniently made around the clock at all Chinese hotels open to foreigners by telephone from your home or through your travel agent.You can book your hotels through http://www.86hotels.com derectly. It is very efficious .I have use its service mang times.In China,the most important thing to do is to know how to use Chinese currency. Chinese currency  is called Renminbi (people's money), often abbreviated as RMB. It is issued by The Bank of China and is the sole legal tender within the People's Republic of China. The symbol for RMB is ¥. The unit of Renminbi is a yuan and with smaller denominations called jiao and fen. The conversion among the three is: 1 yuan = 10 jiao =100 fen.Hope my tips are helpful to you!
