2. Sell cosmetics or shampoo. He will take you to the supermarket to verify whether your shampoo is genuine or not, and then sell you a box, saying it is a work-study program. When you get this box of shampoo, you will find that it is basically fake, and the shampoo is very thin.

3. sell school supplies. He will carry a schoolbag with some nice things to sell besides refills, such as a good photo album. He will say that all these things are fifty cents, including refills and pens, which are fifty cents. Obviously, the value of that photo album is far more than 50 cents. Buy small and cheap. Of course, the reason is that you can resell refills and the like. He will also give you a price list. It will be profitable, but I don't know that all he sells are fifty cents each, and some refills are not worth it at all. When you finally pay the money, you will find that you bought a bunch of waste products, some of which are useless and of course can't be sold. Of course, the salesman may also give you his schoolbag and say that he bought so many things for you. I realized this again, because I was cheated by the dormitory.

4, a little girl, very poor, went to the boys' dormitory and said that she needed some money to go to school. Well, it depends on your performance, but maybe she will go several times. If there are too many, she is naturally a liar.

5. An old man said that he had no money to go home and asked for two dollars. Of course, this has been repeated many times. After a few months, you find that he still has no money to go home.
