《国语·晋语·里克杀奚齐而秦立惠公》
杀了奚齐和卓子以后，里克和丕郑让屠岸夷去狄国告诉公子重耳说： 国家动乱，民众受到惊扰，动乱时才有得到君位的机会，民众受到惊扰的时候反而容易治理，你何不回国来呢？
既杀奚齐、卓子，里克及丕郑使屠岸夷告公子重耳于狄，曰： 国乱民扰，得国在乱，治民在扰，子盍入乎？
After killing Xi Qi and Zhuozhi, Li Ke and Pi Zheng asked Tushan Yi to go to the country of Di and tell the son Chong'er and said: The country is in chaos, and the people are disturbed. Only in the chaos can you have the opportunity to get the throne, and the people are disturbed. When the time comes, it will be easier to govern. Why don't you come back to China?
