《资治通鉴·晋纪·晋纪二十二》
张先、杨初全都是因为顽抗抵御，拒不降服，所以秦国的先帝才讨伐并擒获了他们，然而又赦免了他们的罪行，用官爵俸禄宠待他们，这本来就不是石氏可比的。 
张先、杨初皆阻兵不服，先帝讨而擒之，赦其罪戾，宠以爵秩，固非石氏之比。 
Zhang Xian and Yang Chu both resisted stubbornly and refused to surrender, so the previous emperor of Qin attacked and captured them, but then pardoned their crimes and gave them official titles and salaries, which was not comparable to the Shi family.
