When you enter the dormitory area to sell products, you should refuse to buy them and send them away politely.

First, the advertising language clearly identifies itself and refuses door-to-door sales.

The door says I'm a sophomore and a junior. They think that you are just a group with needs and easy development, but they don't know if you are a freshman, so they will know that you are not a freshman and will avoid their interruption. Don't refuse embarrassment. They just see that you are not a local or don't know much about it after graduating from high school, so they have the courage to fight for it. Besides, all the daily necessities we need are ready, so there is no need to spend this money.

Second, don't be greedy and cheap, and don't be brought in by their words.

Every freshman year, many seniors or senior sisters will come to the dormitory to sell in the name of senior sisters. Don't be greedy and cheap. Usually, they bring some small gifts. If you accept them, you will have to buy their things. And don't be tempted by the rhetoric of your senior sister, such as English grading materials and postgraduate courses.
