'9) Yuncheng IELTS "School". Yuncheng IELTS school is not a school at all, it is a recruiting organization. IELTS is not taught there, never has been. Totally unprofessional, rife with incompetence. Avoid!'

In my opinion your asessment of Yuncheng IELTS school is far too harsh.
You should deleet it from your list of crap\ pretend schools in China\ Thailand.
