The teacher has a negative attitude towards the students. When a student mentioned they would study here for 3 months, the teacher said it wasn't enough and didn't encourage them in their studies.
The teacher doesn't put effort into teaching me compared to other teachers. He lacks enthusiasm in teaching and looks displeased when I answer or can't do something. He also shakes his leg while teaching me.
He is not suitable to be a teacher here if he doesn't improve himself.
