《新唐书·列传·卷四》
当时高祖出巡仁智宫，秦王世民与齐王元吉随从。建成对元吉说： 秦王将遍拜诸妃，他的金银宝物很多，尽可拿出来赠送。
时帝幸仁智宫，秦王、元吉从，建成谓元吉曰： 秦王且遍见诸妃，彼金宝多，有以赂遗之也。
At that time, Emperor Gaozu went on an inspection tour of Renzi Palace, and Qin Wang Shimin and Qi Wang Yuanji accompanied him. Jiancheng addressed Yuanji: "The Qin Wang is going to pay visits to all the consorts, he has a lot of gold and silver treasures, you can feel free to take them out and give them away."
