《左传·文公·文公十六年》
没有一天不进出六卿的大门。对国内有才能的人，没有不加事奉的；对亲属中从桓公以下的子孙，没有不加周济的。
无日不数于六卿之门，国之材人无不事也，亲自桓以下无不恤也。
There was no day when he did not enter and leave the gates of the six elders. For the talented people in the country, there is no one who did not serve; for the descendants of Huanggong and below in the family, there is no one who did not help.
