Directions to Guangzhou clothes market

Hi
A few years ago I went to a large wholesale clothes market in Guangzhou lwith an exit opposite the police academy bus stop (we took a bus from the Guangzhou Railway station to get there) . Unfortunately I do not have any business cards from any of the shops and cannot find the address of the police academy to narrow down my search however I do remember that it is almost below a flyover and there was also a big wholesale shoes mall on oposite the street. Do you know which market I am talking about and which bus I can take to get there? I appreciate any help as I will only be in Guangzhou for 1 day on Sunday.
Thanks alot !
