Several places are small, so you can ask the seafood merchants in the vegetable market to bring the goods every morning. Businessmen in the morning market or fixed hall can ask. Merchants in the vegetable market have to go to the market every morning, and they can earn some wholesale money with the goods. Generally, someone will do it. For medium or large quantities (such as partnerships), you can go to the local wholesale where these vendors load goods, which is generally the seafood wholesale market in various regions, or you can go directly to the wholesale market to see if there is a small batch of wholesale. For example, there is such a market in Shenyang Development Zone.
