"The Great Lord's servant brought his fan in this very morning needing repair for a moon viewing this evening" replied the Apprentice. "I have no ribs to place in the fan but a Farmer's fan I am working on had a rib that would fit. I was cutting out the rib from the Farmer's tessen to place in the Great Lord's tessen."
"Do not cut" replied the Tessen Master. "I will replace the Great Lord's fan with one of equal appearance. The Farmer's fan was delivered in trust that we would do our best work. We dishonor that trust if we act merely to avoid discomfort."
Application: Damaging one thing to fix another is to fix nothing at all.
