My son has studied for two years. Before that, I also heard a lot from my friends. I finished studying and paid the annual fee. In the long run, it is very helpful for children to use their brains and develop good habits. My son used to be poor in independence and didn't like thinking. Now he's fine. I think it is very helpful to learn from KMI. At the same time, I know that it is a course in Taiwan Province Province, and many kindergartens in Shanghai are using it. I think it is good. At the same time, Huisheng's teacher is also good. I hope I can help you.
