As the parents of Leibo Leibo students, I think Leibo Leibo is profitable. It charges a lot of items, and the price transparency will not cause parents' resentment. Most parents around me who study at the same time will add these extra items to their children. First of all, the most important thing is the cost of class hours, including training tuition and parents' renewal fees, which is the most basic; If parents don't have time to take care of their babies during the winter and summer vacations, they can enroll their children in a short-term hosting course in Laibo, with a monthly fee; Because classes are necessarily graded, there will be competitions, registration and equipment fees for graded exams, training fees for competitions and graded exams (I heard that there will be rebates for small competitions), winter camps and summer camps, tuition fees for international tours, and so on. All together, the income of the organization is considerable. Go back to Baidu for other information.
