Some rural parents consider that girls are not the main target of human traffickers, so they allow their daughters to play outside alone. Unknowingly, girls face another danger - sexual assault. On March 5th, Xiao Shan (a pseudonym), a 4-year-old girl in Bandong Village, Jiuxu Town, Hechi City went missing. That night, her body was found at a nearby abandoned construction site. Who would have thought that the brutal suspect was actually an old bachelor who lived next door.
