There are two realms of Yin and Yang in the world, and life and death are orderly. However, there are dead people who have great obsessions, great grievances, and great sins. Their souls are restless and their resentment condenses on their skin. Only the "yin and yang tailor" who inherits ancient taboos can peel off this skin with secret methods and sew it into a special shroud - which may comfort the souls of the deceased and help them die; it may carry the last wishes and resolve the cause and effect; but it may also arrest evil spirits, reverse the yin and yang, and cause catastrophic disasters.
