In order to improve students' awareness of traffic safety and strengthen self-protection awareness, on September 8, Tsinghua High School invited Officer Zhang Yufu of Haidian District Traffic Detachment to the school to make a report on traffic safety for all students in grade one。Through rich examples and vivid animation, Officer Zhang Yufu told the students about the universality, abruptness and cruelty of traffic accidents。The report made the students realize the importance of obeying traffic safety, so that the students know that obeying traffic safety should "start from the small things, start from me".。
