On March 13, our school’s politics teacher, Lu Xiaowan, gave an open presentation in our lecture hall. The topic was “prevent bullying (欺凌) to keep our campus (校园) safe”. More than 300 people, including our city and district leaders, director of moral education (德育), and parent representatives attended the lesson. Ms Lu’s presentation received a lot of praise. The class was broadcast live (现场直播), and all the other students in Bao’an watched it online.
