The male students in our class are very feudal. They always feel that "men and women are inseparable" and are always reluctant to talk to us girls. Even those male classmates and cadres often stay away from us. I often want to find an opportunity to change our minds. ||

That afternoon, I packed my schoolbag and started running to the hospital. I can go to the front line of the ward. It's really embarrassing for a female classmate to visit a male classmate! But the idea of "let my zēng tiān change the thinking of male students" gave me strength. I took a big step and pushed the door open.

His expression really made me laugh: he looked up and saw me, his mouth wide open and his eyes wide open. I smiled and said, "What? Come and welcome me? " It was a long time before he woke up, lowered his head and whispered like a mosquito, "Oh, welcome, please sit down."

He touched his head and smiled shyly. ||

The eyes that my classmates shot at me no longer included ridicule and surprise, but included appreciation and admiration. ||
