Take Line 2 (Chongwenmen direction) and get off at Xuanwumen, then transfer to Line 4 (Tiangongyuan direction), get off at Xingong at 7 stops (Tiangongyuan wants to take 17 stop), take the special passage and take the Pro- 1 bus (as instructed in the station), get off at Dabao Station and take Fangshan Line at the subway station through the special passage.

Arrive at Beijing Railway Station after 6: 00, and then take the subway after leaving the station. If you are quick, you can take Lin 1 road before 7 o'clock. At that time, the road conditions were ok, and it took 20 minutes to get to Dabaotai. Plus the running time of Fangshan Line, we can reach Liangxiang University Town before 8 o'clock. Even in traffic jams, Pro 1 is faster than other bus lines. After all, it is a one-stop direct, taking the main road of the South Fourth Ring Road.

If you have a bus card, the whole subway is 40 minutes from 2 yuan +Pro 1 Road, not 3 yuan.
