First of all, you should prepare your children's award-winning materials and quality reports (which are available in primary schools) and hand them in to the school (these days are just the time to hand them in)

Then wait for the call from the school and inform your child to take the selection exam. (The content must be difficult. Generally speaking, the exam has 2-4 rounds. )

If your child is good enough, you can sign the contract directly. (For example, there are first prizes in mathematics and information contests. I don't know how much is needed. It varies from year to year. )

Suggestion: If the child is strong in science, choose Shu Ren; If you are interested in English or small languages, choose Nanwai!
