《史记·十表·建元以来侯者年表》
后进好事的儒者褚先生说：太史公记事到孝武帝之世为止，所以我又撰记孝昭帝以后功臣封侯的情况，编于左方，目的在于使后世之人能从中看到功臣们功业成败，享国长短，侯位有的传世有的绝封的必然之理，吸取教训，引以为戒。
后进好事儒者褚先生曰：太史公记事尽于孝武之事，故复修记孝昭以来功臣侯者，编于左方，令后好事者得览观成败长短绝世之适，得以自戒焉。
Later, the benevolent Confucian scholar Mr. Chu said: Tai Shigong's record of events ended with Emperor Xiaowu, so I also wrote about the situation of meritorious officials and marquises after Emperor Xiaozhao. It was compiled on the left so that later generations can see the reasons for the success and failure of the meritorious officials and the length of their reigns and the inevitability of some marquisates being passed down through generations and some being abolished, so as to learn from the lessons and take it as a warning.
