i will be in Yiwu after a week !!hope can rent an appartement for month near Futian market!!is that possible??

As I know, you can find an apartment for monthly rental around the H zone of the market. I saw such advertisements at the Chengxi Communicty (诚信小区) close to H zone.

To make your rental more feasible and accessible, I suggest you write a thread or find a suitable on the Ad Board at the community:
