Zhang Lili, a Chinese language teacher at No.19 Middle School of Jiamusi in Heilongjiang Province, has recently been considered to be “the Most Beautiful Teacher” in China.
At 8:38 pm on Tuesday, May 8^th, 2012, Zhang Lili and her several students were waiting for a bus at the school gate when suddenly a school bus lost control and rushed towards them. When she realized the danger, she pushed two students to safety, but she was hit and run over. The 29-year-old teacher lost her legs.
“She is a backbone(骨干) teacher in our school. She works very hard,” said the headteacher.
The heroic teacher was the most popular teacher among the students. “Her students love her a lot. Her room is always full of students when she is free,” said another teacher.
Zhang Lili was also very generous. “My son has lost his father. Every month, Zhang secretly put 100 yuan in his desk from her own salary(工资) to support his studies,” said a boy’s mother, who was waiting outside the emergency room(急诊室) for hours to express how grateful she felt towards Zhang.
Two weeks later, Zhang Lili came out of her coma(昏迷). She wrote a letter to her students, wishing them good luck on their entrance exams for high school. Her letter, 200 words long took her three days to write.
