《资治通鉴·梁纪·梁纪五》
他曾经召集众王爷一同设宴饮酒，所用酒器有水精盅、玛瑙碗、赤玉杯，都制作精巧，皆非中原的出产。
尝会诸王宴饮，酒器有水精锋，马脑碗，赤玉卮，制作精巧，皆中国所无。
He once invited all the princes to have a banquet together, the wine glasses he used were water crystal cups, agate bowls and red jade goblets, they were all made delicately and were not produced in the Central Plains.
