It is the address of a university.
Do you want to send an item back to them or?
Did you buy anything from them? Most probably, they are scams, ad a valid company will provide the detailed address and zip code. 510000 is the zip code for the whole guangzhou. But for a specific area, the zip code varies, for example, the zip code of the address you provided is 510275

It is an item from an ebay seller, Jerseywholesaler2001, and the only company name is what was shown on the shipping label, Hao Bang Trading Co., Ltd in Shanghai. The address for it was in Chinese symbols, so we can not read it and asked for it in english. They gave us the No.135, Xin Gang Rd address and the name Min Hang, but no company name.

I am sure they are frauds, (the jersey I bought is definitely a fake), and are giving me a bad address so they can say they never got it and not give a refund. Thanks for your help.

I had the same problem, did you ever figure out the address of that company?

Paypal gave me the address, during dispute resolution... however it was useless, because paypal required online tracking in order to refund my payment, and the cost of that would be at least $25. I got the company to refund $20 of the $42 paid. So it basically came out same as if I had gone through the hassle and time to return it. NEVER BUY ON EBAY FROM CHINA
