What is the quality of teachers at Dehong School? Have any parents done any research?

Dehong School has an international professional headhunting agency to help them find teacher resources. I have long heard that they have very high requirements for teachers, and the background will be traced back to whether they have criminal records before the investigation. In this school, the admission rate of English-taught teachers is also very low. In addition to examining academic qualifications, experience, qualification certificates, etc., cultural fit is also a key consideration. In short, all aspects are very high-level.
