On the evening of July 9, an old man in Lanzhou stood on the zebra crossing with a brick in his hand. Whenever a vehicle ran the red light, he would throw the brick at the offending car. According to incomplete statistics, about 30 cars were hit that night. The old man said he was teaching immoral drivers a lesson. Some applauded his actions, while others thought that what the old man did was understandable but still illegal.
