Taxis are the default mode of transportation for many foreigners in Beijing. Have your destination written down in Chinese and hail a taxi down. Make sure there is a taximeter and it starts at its initial point. You can also use the popular ride hailing app Didi if you have a Chinese phone number and internet access. Beijing taxi drivers may speak only a little English. Expect to get your change; tipping is discouraged. Taxi from the airport to the city centre takes approximately around 50 minutes, depending on the traffic. Ask for your receipt by saying "Fa-piao / 发票" The Beijing Bureau of Communications takes complaints concerning taxis, minibus or other vehicles. No operator, but an English recording that gives instructions for faxing your complaint—which of course will mitigate your anger right away.
