Wu Ding’s expedition against the Demon Region

Wu Ding’s expedition against the Demon Region appears in the line texts and commentaries as a hard-won campaign whose three-year duration tests the difference between justified force and reckless action. The account makes the expedition a practical lesson in military judgment: even a successful enterprise can be tedious, and its conduct depends on capable leadership, persistence, and the character of those entrusted with it.

The Campaign in the Hexagram Texts

The episode is attached to line three of the preceding hexagram, where the undivided line evokes Kâo Ȝung—Wu Ding’s sacrificial title—attacking the Demon Region and taking three years to subdue it. The line immediately draws a political and military caution from that duration: small men should not be employed in such enterprises. The achievement is not presented as a quick triumph but as a demanding undertaking whose length makes the choice of personnel consequential.

A Model of Sustained Effort

The commentary identifies Wu Ding as one of the ablest sovereigns of the Shang dynasty and describes his expedition against peoples in the cold, bleak regions north of the Middle States. It allows that the enterprise may have been good and successful, yet stresses that it was tedious. The line’s warning therefore qualifies its praise: an undertaking can be worthy of pursuit and still require patience, sound judgment, and reliable agents over time.

The campaign returns in the following hexagram, where line four urges its subject to stir himself as if invading the Demon Region. The comparison turns the remembered expedition into a standard for vigorous, prolonged effort. The commentary says that the subject, though placed in a position that might otherwise weaken his efforts, is firm and correct; his ruler above him is humble and ready to welcome his work. By exerting himself as Wu Ding did, he may make progress and succeed. The reference is not simply to conquest: it links sustained action to the presence of a receptive ruler and to the correctness of the agent’s conduct.

Rewards, Caution, and Historical Frame

The later line-text promises that after three years rewards will come to the leader and his troops from the great kingdom. The commentary explains this in terms of the practical ties between army and court: expeditions beyond the frontiers were not so remote that communication ceased, and rewards, distinctions, and other encouragement could be sent to the forces. The campaign thus carries an institutional consequence as well as a military one: prolonged service could be recognized and supported by the center.

The surrounding discussion places divination in an ancient Chinese setting where both tortoise-shells and stalks were used to examine doubts. It distinguishes this practice from absolute foreknowledge: consultation concerned whether contemplated plans and circumstances would turn out luckily or unluckily. In the hexagram commentary, Wu Ding’s expedition serves a related but specifically moral and political purpose. Its remembered duration helps assess how a difficult enterprise should be undertaken, while the warning against employing small men and the emphasis on firmness, correctness, and royal support make the campaign an example for judgment rather than a simple prediction of victory.
