“ During the reign of Emperor Huan (桓) , Cao Teng (曹騰) served as Central Regular Attendant (中常侍) [4] , as the Empress's Chamberlain (大長秋) , and was granted the title of Marquis of Fei (費) . Sima Biao (司馬彪) , who wrote the Continuation of the Hanshu [5] , said: Cao Teng's father Jie (節) [6] , courtesy name Yuánwěi (元偉) , was known for his kindness and moral character. Once, neighbours of Cao Jie owned hogs of the same type (or kind) as Cao Jie's hogs. They believed Cao Jie's hogs to be theirs, so they took Cao Jie's hogs back home while Cao Jie did not protest. ”

“ Once the neighbours returned to their home and found their hogs, they were exceedingly embarrassed, so they returned Cao Jie's hogs and thanked Cao Jie. Cao Jie laughed and accepted their thanks. This action was praised by the people [7] of Cao Jie's community. Cao Jie's eldest son was Bóxìng (伯興) , his second son was Zhòngxìng (仲興) , and his third son was Shūxìng (叔興) . Cao Teng's courtesy name was Jìxìng (季興) . In his youth, Cao Teng became an official as an eunuch Attendant at the Yellow Gates. ”
