Issued the first Edict Seeking the Worthy, systematizing merit-based recruitment
Context: After consolidating northern rule, Cao Cao began systematically establishing a new personnel system
Decision: Explicitly stated that moral virtue would not be the standard for appointment, only practical talent, reaffirming this in 210, 214, and 217
Reasoning: The Eastern Han recommendation system used morality as the standard, causing the aristocracy to monopolize talent channels; to break this monopoly, the standard must be fundamentally changed
Outcome: Large numbers of low-born talents entered Cao Cao's group; most core strategists (Xun Yu, Guo Jia, Cheng Yu, etc.) came from non-top aristocratic families
Lesson: The most effective way to break incumbent advantages is to change the rules of the game rather than compete under the existing rules
