which taxi company you recommend to take us from Pudong Shanghai Airpirt to Yiwu&how much cost?Thx

To be honest, no taxi can take you to each YW from Pudong airport, because the taxi journey on the road takes about four hours and a half. So it is hard to tell you the taxi fare.
From the airport, there are two direct buses at 11:30 and 17:10 and the bus fare is around 180RMB per person.
Or you can take the Shanghai subway line 2 to reach Hongqiao Railway Station from the airport and at the train station, there are bullet trains to reach YW.
