What are the business opportunities in cold weather?

Thermal underwear, electric hot water bottles, electric blankets, if you don't have much money, you can try to sell these things or buy some underwear to sell. I don't think it will be very expensive in the supermarket. There are all below 40 yuan, and the purchase price should not be high. The landlord can try.

It may be hot food. Food sells better than goods.
