What does Feng Shui mean when you lose your temper and break the bowl?

When your temper comes up, you must vent it somewhere. When you lose your temper at home, find a worthless bowl and throw it. It has a good deterrent effect, is not harmful, and does not affect Feng Shui. It is the best choice.

If you throw a broken bowl at someone else's house, you are maliciously cursing them.
