《南齐书·列传·卷五十七》
永元末年，希哲进入魏国，伯玉大发脾气说： 我力量衰竭到了这个地步，不能守节义而死，仍希望你在本朝报答国家恩典。
永元末，希哲入虏，伯玉大怒曰： 我力屈至此，不能死节，犹望汝在本朝以报国恩。
At the end of Yongyuan, Xizhe came to Wei where Boyu was overcome with anger and said: “My strength has declined to the point where I cannot adhere to principle and die. I still hope that you will repay the state for its kindness while you are in the current dynasty.
