18 · Repairing Decay (GǓ)
Repairing Decay faces problems compounded over time. It does not evade old damage; it finds the root, prepares before and after, and repairs patiently.

The judgment
Repairing Decay: great success. Favourable to cross the great river. Three days before the beginning, three days after the beginning.
Repairing entrenched damage needs decisive work and time before and after it for observation, preparation, and review.
