How about Ketong Education’s teacher clearance agreement class?

Big liar. The courses are very poor, there is no dedicated tutoring at all, and people are arranged to attend classes at other schools. Many of them are taken along. I spent four days in total, learning shit, and threatening people all day long, "If you don't listen to me, you will be responsible for the consequences." The teaching attitude was very poor. Moreover, many of them do not have teaching qualifications, so even if they deliberately make mistakes, they will not be able to hear them
