First, love their jobs and be dedicated. In many people's impression, the profession of teacher is very relaxed in many people's feelings, because you only need to attend classes and correct your homework. Actually, it's not like this. It can be seen from the teacher's performance that the teacher is preparing papers on the subway. We can see that the teacher is very dedicated and devoted, and we can also know that the teacher is not easy. They should not only impart knowledge, but also teach the truth of being a man. The teacher worked hard to prepare lessons on the subway, which can be said to set a very good example for the students. As teachers, they try to prepare lessons for students on the subway. As students, they will certainly study hard and cherish the teachers' labor achievements.

Second, cherish time. Maybe many people don't think why this teacher is preparing lessons on the subway. If you think about it carefully, you may find that teachers spend all their time with their classmates at school, resulting in no time to prepare lessons. Teachers spend all their time on students at school, so that taking the subway after class is leisure time and needs to be taken out to prepare lessons. If we are on the subway, we must take our mobile phones or relax with our eyes closed. But this teacher is not like this. He cherished the short time on the subway and made full use of it. It can be seen that this teacher cherishes time very much.

Third, the spirit of hard work and selfless dedication. We all know that teachers can't attend full classes at school, which means they have a lot of time to prepare lessons or do other things. But what we see is the teacher preparing lessons on the subway. This shows that teachers spend all their energy on students when they are at school. It can be said that he is a candle, burning himself and offering it to students. How happy it is to have such tireless and selfless teachers as their students.
