Like your students from the bottom of your heart
If we always demand the students to follow rules and meet expectations of them, they will learn the same formula. And when they have their own students, they will apply the same on their students. This is one method of transmission.
In fact, educating by showing in our actions is very important. That is, we have to like our students from the bottom of our hearts, and really feel that they are very good! When we see them, we will think: It is so joyful to be surrounded by this group of students. We need to slowly cultivate such feelings for our students. It is only by then that we will able to educate them well.
