During this period, the most urgent thing for institutions is to recruit new employees, but the high promotion cost makes institutions flinch. In the way of free enrollment, referral can not only achieve low-cost customers, but also continuously improve the visibility and reputation of institutions.

Briefly introduce the recommended scheme that I think is good:

1. Introduce new and old activities. Students can introduce new classmates, continue their classes for free, get discounts or get benefits around the organization;

2. If opinion leaders are found in the teaching work, these people will be more willing to share and serve them than expected, and usually these people can bring more new users;

3. Fighting is the fastest way to spread, and people will be more willing to share lessons, which reflects a person's positive side.
