How can I advertise for free without violating the rules?

Regarding the public service advertisement column next to the community, I think you should contact the neighborhood Committee or the property and tell them that this is the theme of public service publicity. Large-scale posting should be negotiable. If you give them the impression that you are commercial or profitable, I think it will be more troublesome and may face the problem of charging.

In addition, if you don't know what kind of education you are doing, you can also print some leaflets on weekends to convey your understanding to relevant people, or you can contact the school directly, and the school will help you find students, and you can hand them over to the school instead of them.

But if you post small advertisements directly now, it may not be allowed everywhere. If you post them, it may bring you many serious consequences. Urban management, industry and commerce, public security can check you. If the industrial and commercial bureau checks you, you will not only be fined, but also carefully check the accounts and invoices in your company's yearbook. In this case, please think twice.
