There is a jingle among Siping youth. How do you say it takes a long time for a woman to grass when she comes back with mud on her legs?

My teacher is very busy. If you look at her, maybe a few beads of sweat will roll down from her head.

Once, she went to another school to attend classes, just as the head teacher of the whole school was going. But after class, all the other teachers went shopping. Only xu teacher (my teacher) was desperate and hurried back. When she suddenly appeared in the class, the whole class was stunned by her appearance. Suddenly, the class was in chaos: someone was talking, someone was cheering, and someone was booing! Suddenly, a classmate stood up and said to the teacher, "xu teacher, all the other teachers have gone shopping. Why are you coming back? " Xu teacher smiled and said to his classmates, "I came back to tell my father about the paper!" After that, she handed out the paper to each classmate and began to talk seriously. At this time, I found a sweat in the teacher's ear and slipped down at once. ...

This is our head teacher, xu teacher. What a responsible and good teacher!
