School teacher: 40/ hour

Teachers in key schools: 50/ hour

It's basically like this

Personally, I suggest inviting teachers from ordinary schools.

Because the fee is not high and one person can make it up, the effect is good.

Teachers in key schools generally don't fill one person, usually four to six.

But it depends on your level. For example, if you are a tutor, it is better to be an ordinary teacher, but if you want to improve, you can find a teacher from a key school.
