Wu Ding attacked the Khi Fang

Wu Ding’s expedition against the Demon Region is invoked in the I Ching as an example of a difficult campaign that took three years to subdue its target. The reference links prolonged military effort with perseverance, competent command, and eventual reward, while cautioning against entrusting such enterprises to unsuitable leaders.

The campaign in the hexagram texts

In the third line of Hexagram 64, Not Yet Completed, the text names Kâo Ȝung, the sacrificial title of Wu Ding, and says that he attacked the Demon Region but spent three years subduing it. The line uses the campaign as a warning: small men should not be employed in such undertakings. Its emphasis falls not only on the military objective but on the fitness of those charged with pursuing it.

Historical context and duration

The commentary identifies Wu Ding as one of the ablest sovereigns of the Shang dynasty and places his expedition among campaigns against peoples in the cold, bleak regions north of the Middle States. It calls the undertaking potentially good and successful, but tedious. In the text’s account, the three-year duration makes the cost of prolonged action visible and explains the qualification attached to the praise: a worthy purpose does not remove the need for care in choosing personnel.

Recurrence and contrasting outcomes

The campaign returns in the fourth line of the same hexagram, now as a model for energetic and sustained effort. A person who acts with firmness and correctness is told to stir himself as if invading the Demon Region; rewards will come to him and his troops from the great kingdom after three years. The commentary connects this image directly to Wu Ding’s famous expedition and explains that, in those times, campaigns beyond the frontiers remained in communication with the court, which sent rewards, distinctions, and other encouragement to the army.

The two allusions give the expedition more than one function. The third line stresses the danger of appointing small or unsuitable men to a prolonged enterprise; the fourth presents disciplined persistence, under proper authority and with continuing support, as a route to success. The campaign thus serves as a political and military precedent rather than a simple celebration of conquest.

Place in the I Ching’s account of action

The expedition’s recurrence across the hexagram’s lines ties historical example to judgments about timing and leadership. In the first instance, three years marks how arduous the effort was; in the second, the same duration measures sustained service that earns recognition. The account’s focus is therefore not on battlefield detail but on the conditions under which extended action can be justified and brought to a successful conclusion: capable leadership, firmness, correctness, and support from the central government.
