Urgent! How to get to Zheng Jiazhen by bus from Liaocheng?

The new national line can leave at the Iron Tower Shopping Mall (the big alley to the east of Dashunfa Supermarket) and the Fourth Company Courtyard (the Fengcheng Bus Terminal to the west of the bus terminal). The convenient night shift is 5: 30. Try to catch the last shift at 5: 00. Probably not/kloc-every 0/5 minutes or so.
