《左传·僖公·僖公七年》
襄王担心大叔王子带作乱，又害怕不能立为国君，所以不发布丧事的消息，却把将要发生内乱的事向齐国报告。
襄王恶大叔带之难。惧不立，不发丧而告难于齐。
King Xiang was worried about the rebellion of Prince Dai, and was afraid that he would not be able to rise to the throne, so he did not announce the news of the death but reported to Qi and asked for help to suppress the rebellion.
