Primary and secondary school training courses enroll students from Monday to Friday, mainly through these three ways: handing out leaflets, worshiping strangers, and bringing the old with the new.

Supplement: How to do it specifically, provide the following reference methods.

First, distribute leaflets.

1. Billing time: usually arranged after school. At this time, parents and children will be more active and time is not so tight.

2. Billing place: Choose a densely populated area within three kilometers of the campus. Leaflets are not allowed near some schools, so be sure to step on them in advance.

Second, the worship of strangers.

1. Avoid parents' working hours and try to contact them after work.

2. It is best for institutions to provide a unified reference template and invite parents to come to school for experience on weekends.

Third, bring the old with the new.

If the training institution offers evening counseling, it can invite existing students or bring new students to the school for free counseling.
