I want to take some seafood back to my hometown. What should I do if the weather is hot?

Containers that can hold seafood should use foam plastic boxes with vent holes on them, and seafood should be wrapped in plastic bags. There must be no ice and water in the packing box. You can fill the bottle with mineral water and tighten it to achieve the freezing effect. In addition, if passengers check a large number of fresh seafood, they have to go through the freight formalities.
