I studied in Hainan for 4 years. As far as I am concerned, Hainan's education can't keep up with the mainland.

We have learned some knowledge they learned in Grade Two and Grade Three. If you want to study there, it's not that I don't support you. Education in Sanya is really distressing. Public teachers have limited level. My niece's English has Henan flavor, and it is difficult to recognize the 26 letters in the fourth grade next semester. This is so-so in her class. What are poor students like? Ignore it when you get to school, and the charge is still very expensive. Later, I went to study for a doctorate. I can't say how the teaching is. At least, my attitude is good and the cost is not cheap. But fortunately, the children came after school and the teacher watched the homework.
