Maybe in the future there will be a "household X-Ray" to examine the problems in our family. 

The crisis and issue behind the wall of every family inspired me to do this piece. If compare our family to a person, problems may start with tiny quarrels, indiffidence that we never pay attension to. But if you don't try to fix it, the issue (or desease) will grow step by step, and eventually it becomes big problem. Sadly, the issue will cut through every inch of the family, when you realized, the wound is already too deep to cure. Sometimes, the third person is a very good mediator. However demostic issue is private. In some cultures, it is a shame to tell other people outside your family. 

Therefore, from a very literal idea, I imagine this "household X-Ray" and doctors who can "see through" the wall of family and examine the problems. Different color represents the mood and emotion of each family member.
