Preschool education is not compulsory, and there is no subsidy from the state, only supervision. Good public ones have school selection fees and sponsorship fees, and private ones have to make their own profits. Of course, it is more expensive than ordinary, slightly worse public kindergartens. Second, there are many miscellaneous expenses, such as books, teaching AIDS, education fees, interest classes, meals, milk fees, transportation fees, etc. These expenses are not cheap. Third, learn to charge privately. In short, preschool education is the "golden starting line", and it can't be saved if you want to save it.
