Zhang Lili: The most beautiful teacher in China

    Zhang Lili is a teacher at No.19 Middle School in the city of Jiamusi, Heilongjiang province. These days, many people think she is the most beautiful teacher in China, because she saved her students from a traffic accident (交通事故) on May 8, 2012.

On that day, Zhang and her two students were crossing the road outside the school gate when a bus suddenly lost control (控制) and ran fast towards them. Zhang pushed both students out of the way, but she herself was hit (被撞倒) by the bus. As a result, the 29—year—old teacher lost her legs.

The principal of No. 19 Middle School, Jiamusi City, said, "Zhang is a great teacher in our school. She’s also the most popular teacher among the students. For the students, she is like a sister. They call her Beautiful Sister. After hearing about this accident, all the students in her class cried." But Zhang is more than a teacher and sister to the 53 students in her class.
