im going to shanghai, how do i get to yiwu from airport?

Hi, but there are two airports in Shanghai. Which one are you going to? Pudong Airport or Hongqiao Airport?
Well, if you are at Pudong Airport, the long-distance buses for Yiwu depart at 11:30 and 17:10. It costs CNY 180. And the whole journey takes about 4.5 h.
If you are at Hongqiao Airport, I adivise you walk to Hong Qiao Railway Station first. There are many bullet trains for Yiwu. And it takes about 2.5-3. The ticket fare is CNY 90 for second-class seat and CNY 108 for first-class seat.
