Do not walk alone late at night. Generally speaking Shanghai is a safe city to walk around at night but still this should be avoided. Do not carry too much cash on you. Shanghai like most major metropolises is filled with pickpockets. Obviously this applies only to crowded areas such as railway stations, the airport, and renowned tourist attractions.
Guard against illnesses such as diarrhea and respiratory infections. Eat only packaged or freshly cooked food and drink only bottled water. Shanghai suffers from air pollution attributable to the growing industries and the growing numbers of cars on the road. Whilst air pollution is not as severe as that in Beijing, tourists are advised to carry anti-allergic medicines with them and to wash their hands, eyes and mouth often. Alternatively, they can also use a face mask to protect themselves from pollution.
Be careful while crossing roads, Shanghai is known for its reckless drivers who stop for no one.
Make sure your travel insurance includes your health insurance as Shanghai's hospitals and doctors charge exorbitantly for their services.
