How about Gleiter Foreign Language School?

Second-rate garbage training class, cheating people who don't know. They cheat people all day in the column of Central Knowledge Tree under the banner of Hong En English, and teach through pyramid schemes. Garbage in garbage. Everything is fake except that the textbooks used are other excellent teachers in Hong En. You can be a teacher with a CET-4 certificate, and then run for a while. What do you think?
