How do extracurricular tutoring institutions publicize?

At present, the publicity methods commonly used by extracurricular counseling institutions:

One is outdoor advertising; This price is relatively high.

Second, SMS advertising; It is said that you will be complained if you send too much.

Third, human flesh advertising; Cycling, placarding and the like.

Fourth, publicity leaflets; This is the most used, but the effect is the worst. If you don't use it, you feel that a lot of information can't be transmitted, and a single page has the largest amount of information.

5. Organize various activities and do conference sales. Unless it is a lecture of NB, it is difficult to invite people from NB. Now that parents have seen more, it is quite difficult.
