You mean to come to our side by train! Now our train station in Yiwu has been moved and called the new train station. There you can take the No.804 bus and get off at the Wang Bin market, where there are the wholesale insoles and sewing threads you want. Then you can transfer to Bus No.9, No.6 and 1 at Wang Bin Market to go to the old commodity city, so you should look at the direction of the bus when you take the bus! :)
