He was of medium height, with a melon seed face, black hair, and a pair of large, shiny eyes, and looked shrewd and capable. He is Mr. Liu, who tutored me in the Bowen Education Training Class to write essays.

Because the teachers in my class in the school are all female teachers, when I first met Ms. Liu, I had a kind of alienation and prejudice against male teachers, thinking that male teachers are not as good as female teachers. Male teachers are more fierce and not as gentle and amiable as female teachers. Therefore, many times I was reluctant to take composition classes, and even if I sat in the classroom, I felt uncomfortable mentally and did not pay attention to the lectures.

One day, Mr. Liu was lecturing, I couldn't understand anything, I raised my hand to ask, Mr. Liu not only did not get angry, but also patiently explained to me in a gentle tone, I was very moved, ah, male teachers were not all so grumpy, I felt that my previous thoughts were wrong, and things were not what I imagined. Since then, I have been taking the lectures seriously.

Who knows, my tablemate drew a big turtle on one of my test papers, and I saw it, and I cried out loud with a "wow", and the tears fell like beads of broken thread. Teacher Liu came over and asked me what I was crying about, and after he understood the reason for the incident, he severely criticized my tablemate, and then he comforted me in a kind voice: "Good friend, don't cry, it's okay, I've already criticized him......."My whimper grew quieter.

I deeply felt Mr. Liu's care for students.

On the day of the end of the training class, he walked into the classroom with a smile on his face, played a game with us, and then started to lecture. Mr. Liu imparted the knowledge he learned and the writing methods to us without reservation.

Now that Mr. Liu and we have not seen each other for almost a month, I am very much looking forward to Mr. Liu giving us a composition class again. I really hope that the day when Mr. Liu will guide us in writing essays will come sooner.
