As far as I know and see, Yidelu seafood wholesale market in Guangzhou should be the largest wholesale market for dried shark's fin, dry sea cucumber and dried abalone in Chinese mainland. There are many shops on Yide Road, next to which are several wholesale markets, such as Nanyue seafood wholesale market and Haizhongbao dry goods wholesale market. Large quantity-each company has its own special items, many of which are pavements directly set by processing plants, and quantity is not a problem.
If you want to find the biggest one, go to Yide Road and have a look, my friend!
