1967年8月，廣州掀起打“勞改犯”運動，當局嘅文革思想係公眾應對“階級敵人”充滿“階級仇恨”，而“勞改犯”屬於“階級敵人”。喺廣州城內德政路度有最多人畀殺，當時只要有人嗌一句“呢個係勞改犯”就即刻會有一班人埋去用木棍、水喉鐵通，甚至係掹槍去打死渠。據報，吊死、閘死、打死同打死後拋落珠江嘅人數幾乎達到200人。
In August 1967, Guangzhou launched a campaign against "reformed labor prisoners", and the Cultural Revolution ideology of the authorities was that the public should be filled with "class hatred" against the "class enemy", and the "labor prisoners" belonged to the "class enemy". At that time, as long as someone shouted that it was a labor prisoner, a group of people would immediately go over and beat the ditch with wooden sticks, iron pipes, iron pipes, and even guns. It has been reported that almost 200 people were hanged, locked, beaten and thrown into the Pearl River after being killed.
