I am a good person.

This is a classic Chinese style 'black humor'. 1 rag picker who is at a loss for a living, 1 bear child born into a wealthy family but without happiness, and 1 hysterical woman who goes crazy for the child in her bellyA man, a wealthy father with a wealth but suffering from unborn and already born children, and two playful kidnappers. They all unintentionally performed a tragic comedy of life.
