I have been making clothes for several years, and there is a tail market in Changgang. Poor quality, suitable for setting up stalls. If you pack it, you will usually take it to the warehouse. The price is very cheap, but it is not recommended to get the goods in bulk.
You can consider Yimin Clothing City with the following address:
Guangdong Yimin clothing city
Address: No.27 Li 'an Road, Tianhe District
I don't know if it is convenient for you.
