《资治通鉴·隋纪·隋纪三》
我每每想到东宫皇太子竟然没有正室，在你们皇父百年之后，让你们兄弟几个跪拜问候阿云儿，这是多么痛苦的事啊！ 
每思东宫竟无正嫡，至尊千秋万岁之后，遣汝等兄弟向阿云儿前再拜问讯，此是几许苦痛邪！ 
Every time I think about the fact that the Crown Prince of the Eastern Palace does not have a proper wife, that after your imperial father passes away, you brothers will have to kneel down and greet A Yun'er, it is so painful!
