Hello, this parent, I think you know many remedial classes or schools in Siping that teach official document mathematics. The child is only 6 years old, so don't put too much pressure on the child. You should always communicate with your children, and don't bury their inner potential. Just give the child a little pressure, not too much pressure. In fact, any school is the same. If you want your children to learn official document mathematics, you'd better know something yourself, know a little knowledge and give them some guidance appropriately. Today's children know things very well, and they will understand if they reason with them.

My colleague's child learned to find evidence when he was three years old. ...

It's best not to let what you haven't finished before be handed over to the next generation-
