地铁：In recent years, more and more Chinese cities have begun to build subways as part of the efforts to reduce traffic jams and air pollution. A growing number of people now choose subway as the major means of transportation to work or school every day for the safe, fast and comfortable travel experience it has to offer. Nowadays, as card or mobile payment gains popularity in some Chinese cities, it is becoming increasingly convenient to take the subway. Many local senior citizens are also entitled to also enjoy free subway rides.
飞机：In the past, it was difficult for most Chinese people to imagine a time when they could travel by plane. At present, however, with the development of economy and the enhancement of living standards, Chinese people in increasing numbers, including many peasants and migrant workers, are able to travel by air. They can reach all big cities by airplane and many cities are preparing to built airfields. Air services have been continuously improved and there are often low cost airlines. In recent years, the number of people who would like to travel by plane during holidays has been growing.
公交：Buses used to be a majortraffic tool for Chinese people when they were getting around. In recent years, traffic problems in cities have been increasingly severe.

Vehicle facilities have been continuously renewed and the vehicle speed has been dramatically enhanced. However, the bus fair has been kept quite low. At present, many local senior citizens in most cities can take a bus with no charge.
