In fact, children are not easy to learn, and there are only two points: 1, they will not get started and are not interested; 2, the method is wrong, and the efforts are in vain.
Many institutions dare to start classes by hiring a part-time student. Many institutional bosses are untrained, some are chefs and some are drivers. Anyway, the boss is not professional, and the teachers invited are average.
Huizhi can train teachers and civil servants here, and teachers are particularly powerful. It's not a loss anyway. If you really want your children to learn well, you have to find the right institution.
