《三国志·魏书·崔毛徐何邢鲍司马传》
当时太子人选还没有确定，而临菑侯曹植受到恩宠，毛玠暗中劝谏太祖说： 眼前有袁绍因为嫡子庶子不区分，导致宗族覆灭，国家败亡。
时太子未定，而临菑侯植有宠，玠密谏曰： 近者袁绍以嫡庶不分，覆宗灭国。
At that time, the crown prince had not yet been determined, and Linzi Hou Cao Zhi was favored. Mao Jie secretly advised Taizu: Yuan Shao was in front of you, because he did not distinguish between direct and direct children, which led to the destruction of the clan and the destruction of the country.
