Shanghai is a nice city. The weather here is mild (温和的), that is, it is neither too hot nor too cold. It changes from season to season. Now many tall buildings have been set up one after another. But at the same time, the city is full of people. As a result, the traffic is terrible. Traffic jams (拥挤) happen during the rush(高峰) hours. If you want to go to a place far away, the fastest way is neither driving, nor riding a bike. It is often walking! The policemen in Shanghai are very helpful. Visitors can ask them for help if they lose their way or lose something. But when you disobey (违背)the traffic rules, they will be very strict with you. A lot of people in Shanghai can speak English. Travellers from English speaking countries feel at home here. Welcome to Shanghai.
