Kindergarten teachers will teach children some basic things, such as playing, cooperation and counting. Most kindergartens are private, which can be two years old or one and a half years old. Kindergarten should be three years old. Of course, private ones are not too strict. Personally, I think that proper early education has certain effect, but it is not very great. We should give our children a happy childhood. American children really study hard at university, and China has won numerous Nobel Prizes. It is most important for children to teach them how to behave in childhood.
