I want to go from keqiao to yiwu to Quzhou retun to keqiao in two day

I remmeber buses form Keqiao to YW are scheduled from 06:40 to 15:50 for your reference. You will be taken to YW Binwang Bus Station in around two hours. To Quzhou, you can take a bus from Nanfang Bus Station. The bus schedule is from 06:50 to 17:20. The bus fare is CNY47 and it takes around 1.5h.

From Quzhou to Keqiao, there is just one direct bus every day. It leaves Quzhou Passenger Transport Center at 07:40. It takes around 4h and costs CNY94 per peson.
