You have introduced yourself too little to help you formulate reasonable, effective and targeted methods. Then I'll give you some little ideas under normal circumstances!

1 Schools should have dry cleaners or washing machines or small shops. If there is a dry cleaner, talk to the shopkeeper and tell her why it is so difficult for you to ask her for help, and pay as little as possible (it is best to spray a photo and stick it on the wall or in a conspicuous position such as a washing machine, for the simple reason that you can see it as long as you wash it. If you wash too much clothes, you will naturally buy clothes. )

Print some colorful leaflets for several hundred dollars and send them to all dormitories on Monday (the content is vivid and attractive, and it is best to insert them on the door with excellent effect)

School supermarkets, hair salons and bathhouses can all go around and make stickers.

There are also some good clothing display pictures in Renren.com, including the contact information of classmates and friends, and the QQ group of the school.
