Pro: That is, your child has not only learned a little self-defense, but may also know how to cultivate self-cultivation there, so it is not so impressive. I still suggest that your children go there and experience it for themselves. It's no use being at home. Going now will not delay school, but also give him a full and meaningful childhood.
Disadvantages: You will miss him very much, and he will miss you more. It's hard to leave home at such a young age. After all, it is not a holiday.
If you don't send good seedlings, you will regret it when you grow up. After all, it's only two years.
