Travelling to Yiwu, what is the easiest way to get there?

Neal, you should fly to Hangzhou first if possible. There you can take long distance bus from the airport to Yiwu. It departs at 10:20, 11:00, 11:40, 12:20, 13:00, 13:40, 14:20, 15:00, 15:40, 16:20, 17:00, 17:40, 18:30, 19:30, 20:30 and 21:30. The ticket fare is CNY 62.

I am thinking of flying to Ningbo. Is that a better option?

Thanks for the infor Nelson.

Neal, it's ok. You can fly to Ningbo and then catch a taxi from the airport to Ningbo Central Bus Station (Ningbo Zhong Xin Qi Che Zhan). There you can take bus to Yiwu too. It costs CNY 72 and departs from 06:30 to 18:10.
