Cao Cao.

In order to select more talents, Cao Cao broke the feudal standards of appointing officials based on their moral virtues and the rank of their disciples, and put forward the employment policy of "approval based on talents." Cao Cao put forward the policy of "recruiting only those who are qualified for recruitment" and issued three orders including the "Order to Seek Talent", emphasizing the selection of talents regardless of their origins or moral conduct, as long as they have the skills to govern the country and use military force.
