The problem of human trafficking has existed throughout history, but it has received little public attention. The darkness and horror of human trafficking and human organ trafficking are not well known to the public. People have been paying attention to the methods used in human trafficking to kidnap and sell human beings, and to those who treat human beings as money bags and organs as money, but often ignore the prevention of buyers. The poster shows people’s painful expressions. It opens a window of the prison in the kidney, which is more representative of human organ trafficking. In this way, it shows that when you extend your hands to other people’s organs, you are also reaching into the cage.
