I have to travel from Capital airport to wang fu jing after 11:30 pm,can i get get shuttle bus?

The airport shuttle bus line 3 runs to around 24:00, so if you can take that last bus, you can take it to reach its terminal and then take a taxi to reach where you want to go in Wangfujing area.
If you cannot catch that bus, you can take the airport shuttle bus line 2 to reach its terminal and then take a taxi to reach Wangfujing area. The bus line 2 has a night line and it operates 24:00 to the last flight in the airport, so if you take bus after 24:00, it is suggested to take it.
Hope these information can help you.

Thank u very much,sandy. Your information is of great help,to me.
