Moving around in Shanghai is quite easy. The easiest way to do it is by taxi. They are cheap, reliable, and friendly. The only downside is that most taxi drivers do not speak English, and some of them can't even read it. I recommend always bringing a card of your hotel with the address in Chinese just in case. If you stay in an upmarket hotel the license plate of the taxis you take will be written by the hotel's porter on a card for you. Although this is an unnecessary measure in such a secure city, keep it.
The fastest way to move around is the metro. There are two main lines that converge in people's Square, close to West Nanjing Road. The metro fare depends on the number of stations. Look at the counter desk boards, and pay accordingly. Stations and signs are in English and Chinese.
