Currently, the Shanghai Pudong Airport supplies two coaches to Yiwu directly, respectively at 11:10 and 17:10.

If you miss the coach, please take the airport shuttle bus Line 7 to Shanghai South Railway Station. Here, you could catch a train or bus to Yiwu, too. Personally, it is suggested that you consider taking a train, which is departed frequently everyday. Well,you could search the train infor at https://www.travelchinaguide.com/china-trains/
