17.121

（甲辰）　改開運。少帝重貴（高祖猶子。祖有六子。皆亡。帝父敬儒祖之兄也。早卒。高祖養帝為子。故得立位。後三年為契丹主耶休德光長驅過河入汴攻之。帝出降封。負義侯送至和龍府。不知何年卒。在位三年）。

[Jiachen (944)] Changed to Kaiyun. The Young Emperor, Chonggui (the nephew of Gaozu. Gaozu had six sons, all of whom had died. The Emperor's father, Jingru, was Gaozu's elder brother and died early. Gaozu raised the Emperor as his own son, and thus he gained the throne. Three years later, the Khitan ruler Yelü Deguang drove straight across the river, entered Bian, and attacked him. The Emperor surrendered and was enfeoffed as the Marquis Who Turned His Back on Righteousness. He was sent to Helong Prefecture, and it is unknown in what year he died. He was on the throne for three years).
