FamilyIsNotYourPunchbag / interactive advertisement

"Punchbag" looks just like a sandbag. Placed in public places, the bag will start to play a male, female or children’s crying sound whenever a person comes up and punches it.
We want to remind people that family is not your punchbag, you have to start preventing the domestic violence yourself.
With the time progressing, modern people get more and more pressure. Anyone could be the perpetrators. If we repress ourselves too much, maybe we will be the next one to commit the violence. Reducing the number of the perpetrators is the best solution to prevent the domestic violence.
