《礼记·坊记》
所以，鲁国的《春秋》在记载晋国的丧事时说： 晋国大臣里克杀死了晋国国君的儿子奚齐，及其国君卓。 
未没丧不称君，示民不争也。故鲁《春秋》记晋丧曰： 杀其君之子奚齐及其君卓。 
Therefore, in the "Spring and Autumn Annals" of the State of Lu, when recording the funeral of the State of Jin, it said: Duke Li of Jin was killed by Li Ke, a great official of the State of Jin, and his sovereign, Duke Zhuo.
