How much does it cost for foreign children to go to school in Yanjiao every year?

Primary school is different from middle school. There seems to be no sponsorship fee in primary schools, but when looking for a relationship, it will cost less, with a difference of about 10 thousand. This year, some friends around me spend 5 thousand, some spend 15 thousand, and other primary schools are similar. Other primary schools are cheaper, depending on which school is the middle school. The sponsorship fee for the eighth grade may have been four or five thousand two years ago, but now it should not be lower than this. !
