It is convenient and simple to travel by taxi in Nanjing. The taxis are all painted in green. There are some taxi stands on the main streets in Nanjing but the simplest way is just to hail a taxi near the train station, the airport, bus stops, scenic spots or the hotels. It is also advised to use the meter instead of bargaining with the cab driver, however, if you travel to suburban areas of Nanjing, then you should bargain with the driver before you get in the taxi. You can also use the taxi cab hailing service with WeChat or Alipay (like the Chinese version of Uber).
