Hobo symbols invade China’s underworld

Recently, China police made public 17 types of “casing markers/symbols”. “×” represents “plan operation”, ? represents “no one lives here”, a wavy line represents “beware of fierce dog”, while a rectangle with slashes represents “already thieved”. Police remind city residents to be on the lookout for secret symbols/signals made by thieves and to immediately report them to the police as well as remove them upon discovery.
