Education in Hainan is backward all over the country. People's enthusiasm for education is average, school management is relatively loose, teachers' level is limited, and students' academic burden is very light. There is no problem of reducing students' burden in Hainan, and students have nothing to lose. Of course, neither parents nor students are very interested in after-school tutoring or extended learning. You have to do after-school tutoring in Sanya, and the prospects are worrying. In Hainan, only Haikou has a large proportion of migrants, and parents have high expectations for their children. There may be some opportunities for after-school tutoring. However, most of these opportunities are divided up by students from Hainan University and Hainan Normal University who are engaged in work-study programs. It is difficult for others to get a piece of the action except the teachers in Hainan Middle School. Of course, art, foreign languages and sports are another matter. I hope you are careful. Wish you success!
