This poster encourages people not to be silent majority, in the face of human trafficking,we should be brave to make their own voice, so that more people hear our voice. The back of the poster struggled behind the glass wall to get out, but his voice became more and more blurred. Black hands represent silence, white hands represent hope. One more power, one more voice, the world will become better. What we want to hear is: let us hear you, not: shut up.
