Children's interest class. Rent an old warehouse for one year, decorate it with colorful decorations, recruit several fresh graduates (qualified or not) as teachers, take the children to draw, write calligraphy, recite poems, recite lines and so on. Don't charge too much or too little. Try to make it a one-year course and come every weekend. In this way, you can host classes after school starts on weekdays and open interest classes on weekends without conflict. Rest assured, some parents think that "children can't lose at the starting line", but they have no education and are willing to spend money to let their children come. What do children know? What do parents know? Let the teacher amuse the children, write a word and recite a poem. It's not just children and parents who are happy. If another selection contest is held, the profit will be higher.
