Thrice wringing out his hair in one washing
The Duke of Zhou described how he received worthy men: "In one washing I wrung out my hair three times, in one meal I spat out my food three times, still fearing I might lose the worthy men of the realm." He came out three times mid-wash with wet hair to receive guests, and rose three times mid-meal to greet scholars. Cao Cao later drew on this in his "Short Song": "The Duke of Zhou spat out his food, and the realm turned its heart to him" — the image of the regent thirsting for talent fixed here.
Rumor and the return of power
During the regency, rumors spread that "the Duke of Zhou means harm to King Cheng"; even the Duke of Shao grew suspicious, and Guanshu and Caishu joined the Shang remnants in rebellion. The Duke of Zhou campaigned east for three years to put it down, and when King Cheng came of age he returned power and faced north as a subject. Later powerful ministers all compared themselves to the Duke of Zhou, but few ever passed the test of "returning power" — the value of this model lies precisely in how nearly impossible it is to replicate.
