《新五代史·世家·南汉世家第五》
刘龚患病躺在卧室中，召右仆射王翻和他谈话，呼刘洪度、刘洪熙的小字说： 刘寿、刘儁虽然年长，但都不能够担当我的大业，祇有刘洪昌像我，我想立他。
病卧寝中，召右仆射王翻与语，呼洪度、洪熙小字曰： 寿、俊虽长，然皆不足任吾事，惟洪昌类我，吾欲立之。
Liu Gong fell ill and lay in his bedroom, summoned the Right Administrator Wang Fan to talk with him, called Liu Hongdu and Liu Hongxi's nicknames and said: Liu Shou and Liu Jun may be older, but they cannot take on my great undertaking. Only Liu Hongchang is like me; I want to establish him.
