When getting around in taxis, try to have small bills available (RMB 10, 20, and 50 notes). Drivers have been known to use counterfeit RMB 50 and 100 bills to make change for larger denominations. On another urban transport note: Chinese ambulances tend to have little sophisticated medical equipment, and they are usually staffed by people with inadequate medical training. Consequently, if you are ill or injured you may want to consider taking a taxi or any other vehicle at hand to a major hospital. There are also foreign-run medical care facilities available which cater to foreigners and expatriates, but they are more expensive than hospitals and clinics run by local governments. SOS International, Ltd, is one such outfit, which runs clinics and offers med-evac in several major Chinese cities.
