《三国志·魏书·荀彧攸贾诩传》
贾诩自认为不是太祖旧臣，但又出谋划策，思虑深远，担心会被猜忌，于是就在家闭门自守，私下也不与人结交，家中孩子的嫁娶，也不和高门大户结亲，天下论及智谋计略的人当之无愧。
诩自以非太祖旧臣，而策谋深长，惧见猜疑，阖门自守，退无私交，男女嫁娶，不结高门，天下之论智计者归之。
Jia Xu believes that he is not an old minister of the founding emperor, but he is also a strategist and a planner. He thinks carefully about everything, so he is worried that people might be suspicious of him. That is why he does not go out often and would not communicate with others in private. When it comes to the marriage of his children, he would not choose someone from a powerful family. When the world talks about intelligence and strategy, he is definitely a well-deserved talent.
