China's currency is the Renminbi Yuan (CNY), which is divided into 10 jiao or 100 fen. Make sure you exchange your leftover Yuan before returning home because you may have difficulty exchanging the currency outside China's borders. Foreign cash can be exchanged in cities at the Bank of China. It is not possible to exchange Scottish or Northern Irish bank notes. Banks are closed weekends. The larger hotels and the special 'Friendship Stores' designed for foreigners will accept most Western currencies for purchases. Major credit cards are accepted in the main cities, but acceptance may be limited in more rural areas. ATMs are scarce in rural areas.
