It's easy at school. Just contact the school club directly and hold a ball game at school.

In urban areas, the first is the advertising effect, which is publicized in the form of posters and leaflets. Then, the leaflet should indicate the day when there will be activities in a certain place, and the location should be selected in some good schools in parks or urban areas to hold basketball fan activities (it is best to have the capital to tour several schools). So there must be many students.
