May I know what to take from Beijing Capital Airport T3 to Wangfujing Metro Station?

You can take the Airport Express Railway at the no.3 Parking building, 2nd floor, T3 to Dongzhimen Station. The ticket fare is CNY25/person. It operates during 06:20 to 22:50 with the frequency of 10 minutes. Then you can transfer metro line 2 to Jianguomen Station. Afterwards, you can take metro line 1 to Wangfujing Station.
