《资治通鉴·唐纪·唐纪九》
太宗曾闲居无事，与王交谈，有一个美女子在旁侍侯，太宗指给王说： 这是庐江王李瑗的妾，李瑗杀了她的丈夫而收纳她。 
上尝闲居，与珪语，有美人侍侧，上指示珪曰： 此庐江王瑗之姬也，瑗杀其夫而纳之。 
Emperor Taizong once took the opportunity when he had nothing to do to converse with Wang, and a beautiful woman was waiting on him. Emperor Taizong pointed to her and said to Wang: This is Lujiang King Li Yuan's concubine. Li Yuan murdered her husband and took her for himself.
