《旧五代史·其它·僭伪列传二》
原先，刘陟听说庄宗武力强盛，所以派何词来探听虚实，当时后唐朝政已乱，庄宗也没有办法控制后方，南海的贡物也最终不送来了，从此与中原断绝往来。
初，陟闻庄宗兵威甚盛，故令何词来视虚实，时朝政已紊，庄宗亦不能以道制御远方，南海贡亦不至，自是与中国遂绝。
Originally, Liu Zhi had heard that Zhuangzong was a powerful military commander, so he had sent He Ci to investigate the truth of the matter. At that time, the Later Tang Dynasty was already in chaos, and Zhuangzong had no way of controlling the rear area. Ultimately, the tributes from Nanhai never arrived, and all communication with the Central Plains was cut off.
