Most hospitals in big cities provide a high standard of medical care in China. However, in some remote areas, the medical service may not be to such a standard. Ensure your physical condition is good prior traveling. Bring some medicines with you, such as aspirin, anti-histamines and so on. Dial 120 for an ambulance or call your tour guide or hotel staffs for help if you are not in good health. You can also phone the SOS International, 24-hr alarm center in Beijing (010-6542 9100) or in Shanghai (021-6295 0099) for advice on local medical services.
