周公谓鲁公曰：“君子不施其亲，不使大臣怨乎不以，故旧无大故则不弃也，无求备于一人。”
1The duke of Chau addressed his son, the duke of Lu, saying, 'The virtuous prince does not neglect his relations. He does not cause the great ministers to repine at his not employing them. Without some great cause, he does not dismiss from their offices the members of old families. He does not seek in one man talents for every employment.'
