The teacher you mentioned is Mr. Ye Mingrui, and he is the party branch secretary of the TV Department. He is very nice, but his personality is a bit strange. Leave him alone.

You play well with him, he gives you high marks, you mess with him, you will be miserable ~

He mainly teaches the basics of photography. Maybe you can't attend his class. He will go to Australia for four years soon ... well, we will miss him.
