(Li) Kun, then the secretariat of Tianshi Lizi, Wei, Song, Zheng, Liang and You, was named Neng. In the holy calendar, Lingnan rebelled, and Kun recruited him as a comfort envoy, which made him miserable. It is fitting that he died in Chang 'an for two years and gave it to Si. At the beginning of the dragon, it was dedicated to the king of Zhangye County. In the seventeenth year of Kaiyuan, Zi Yigui was given the title of Shang Shu of the Ministry of Industry and posthumously awarded to the Prince of Wu.
Epitaph of Cheng Siyi
From time to time, Prince Kun of Wu worked as a herdsman on the right side of the river, and came to the princes to establish close friends and organizations, so that you could ask questions and trap him to death. Your feelings are deep sorrow and respect, and your ambition is to rehabilitate. It is better to lose it than to feel guilty. So please pick up the sword on the square and break the courtier's head. ..... Cherish the fierce and don't run away, believe and see doubt, slander and read the words, thank you for a long time, and issue the Yanzhou County Order.
