First of all, the quality of your products must be guaranteed, and then you can get a good reputation. You can distribute your products to your friends first. If your product is a mask, you can pretend to casually say how to use this mask when applying it in the bedroom, and then share some with your roommates so that they can use it with you. Don't be reluctant to part with your children. If you want to be generous, then they will ask you where to buy it. You will also share it with their friends, and friends have friends, so your scope is not large. Plus, if you have a good reputation, your products are well-known in school, but the premise of everything is that the quality of your products must be excellent, otherwise how well-known you are and how miserable you will be scolded in the future.
