Taxis

　　Taxis are in the streets 24 hours a day．Simply raise your hand, and a taxi will appear in no time．They are usually red, and they display the price per kilometre on the window．You should check whether the cab has a business permit, and make sure you ask for a receipt．

　　Buses and trolleybuses

　　Public transport provides a cheap way to get around in Beijing．There are 20,000 buses and trolleybuses in Beijing, but they can get very crowded．It’s a good idea to avoid public transport during the rush hour(6∶30 a.m.～8∶00 a.m.and 5∶00 p.m.～6∶30 p.m.)．Fares are cheap, starting at 1 yuan．Air-conditioned buses cost more．Buses numbered 1 to 100 are limited to travel within the city centre．Higher numbers have destinations in the suburbs．Tourists shouldn’t miss the 103 bus which offers one of the most impressive routes, past the Forbidden City and the White Pagoda in Beihai Park．If you get on a double-decker bus, make sure you sit upstairs．You’ll have a good view of the rapidly changing city．

　　Most buses run from about 5∶00 a.m.to midnight．However, there is also a night bus service, provided by buses with a number in the 200s．

　　Minibuses

　　Minibuses with seats for 12 passengers offer an alternative to expensive taxis and crowded public transport in some areas．They run regular services and follow the same routes as large public buses．And in a minibus you always get a seat even in rush hours．

　　Underground

　　There are four underground lines in Beijing, and several lines are under construction．Trains are fast and convenient, but rush hours can be terrible．A oneway trip costs 3 yuan．Station names are marked in pinyin．The underground is open from 5∶00 a.m.to 11∶00 p.m.．

　　Pedicabs

　　Tourists like these human-pedalled“tricycle taxis”, but they can be expensive．You should talk to the driver, and make sure you know the price before you begin the journey．For example, if it is per person, single or return．Tricycles are worth using if you want to explore the narrow alleys(hutong)of old Beijing．
