《新五代史·列传·梁臣传第十》
梁太祖赏赐给他帽子、衣带，用酒招待他，刘郭以酒量小推辞，梁太祖说： 攻占充州，气量为何那么大呵？ 
太祖赐之冠带，饮之以酒，掞辞以量小，太祖曰： 取兗州，量何大乎？ 
The founding emperor of the Later Liang gave him a hat and belt, and entertained him with wine. Liu declined, claiming that he could not tolerate alcohol. The founding emperor of the Later Liang said, “When you captured Chongzhou, why did you seem to have such tolerance for alcohol?”
