If you want to know where there is ice in the ice powder shrimp stall on the roadside, you can go to the ice shop to buy a large piece, take it home and cut it into small pieces, or you can go online to pack it. If you buy an ice pack for reuse, it can be recycled. Then put it into a foam box, which can keep cold for about 20 hours, and the foam incubator can also be recycled.
