Hi, would like to take the bus from Wudaokou to the Oasis Hospital near Wangjing, is there a bus?

There is no direct bus and transfering bus is complex and it is always crowded in that city.
The subway system is suggested.
From Wudaokou Station, you can take the line 13 to Zhichun Road Station and change to line 10 to Sanyuanqiao Station. Then take a taxi to that hospital.
