49 · Revolution (GÉ)
Revolution here means a justified turning of an old order, like a hide whose surface changes. The text insists that trust comes with the right time and conduct. Its six lines begin with restraint, then timely action and repeated consultation, move to a trusted change of mandate, and end by asking leaders to let the new order settle rather than launch another campaign.

The judgment
Revolution: only when the day arrives is there trust. Great passage; steadfastness is beneficial. Regret vanishes.
Trust is not granted at the first announcement. A change must answer a real need, fit its moment, and be carried out with integrity before people can believe in it.
Original Chinese text
革:巳日乃孚,元亨。利貞。悔亡。
