Li Weiqi, a 40-year-old auxiliary traffic police officer in Hangzhou, Zhejiang province, has become a household name after a surveillance video was broadcast showing how he prevented what might have been a major tragedy last week at a busy intersection in the city.

因为一段成功阻止杭州市某个交通繁忙十字路口的（地陷）惨剧的视频，浙江省杭州市40岁的交通协警礼为奇最近成了家喻户晓的人物。

协警（auxiliary police）是辅助人民警察工作的专业群防群治队伍，不具有行政执法权（power of administrative law enforcement），必须在在编民警的带领下开展各项工作。
