有两只孔雀从西苑一起飞到宝城朝堂前面，亲卫校尉高德儒等十余人看见了孔雀，就奏报炀帝说看见了鸾鸟，这时孔雀已经飞走了，无法验证，于是百官们都向炀帝祝贺。
有二孔雀自西苑飞集宝城朝堂前，亲卫校尉高德儒等十馀人见之，奏以为鸾。时孔雀已飞去，无可得验，于是百僚称贺。
Two peacocks flew from the Xi Garden and landed in the courtyard of Baocheng Palace. More than ten people, including imperial guards Gaode Ru and others, saw the peacocks and reported to Emperor Yang that they had seen phoenixes. The peacocks had already flown away, so this could not be verified, and all the officials congratulated Emperor Yang.
