* ‘mentor’ would not work as a synonym of ‘teacher’. It’s much more specific.
* ‘sharpen the career’ does not collocate well.
* “and students often misbehaved with teachers” (misbehave with their teachers)
* “fewer salaries” would be incorrect in this context. Please look up ‘few’ vs ‘less’ to see the difference.
* “Educators should have some power that able them to scold the high” (‘enable’ in the place of ‘able’ )
