Hi, i want to go Beijing to Zhengzhou by bus. Can you help me how to get there?

You can take the direct long-distance bus from Lianhuachi Bus Station. The bus schedules are 10:00, 11:15, 17:00 and 18:00. It costs CNY 175 per person.
From Liangmaqiao, you can take metro line 10 to Hujialou and line 6 to South Baishiqiao Station. Then transfer to line 9 to East Liuliqiao Station, Exit E. Afterwards, walk southwest around 150 yards to find Lianhuachi Bus Station.
