《南史·本纪·卷十》
太建末年，隋兵大举行动，听说宣帝去世，便命令回军，派遣使者前往吊祭，用平等国家的礼节，书信称姓名顿首，而后主越发骄傲，在书信的末尾说： 想来你们那里统驭内部如果适当，这宇宙就会清静太平。 
太建末，隋兵大举，闻宣帝崩，乃命班师，遣使赴吊，修敌国之礼，书称姓名顿首。而后主益骄，书末云： 想彼统内如宜，此宇宙清泰。 
At the end of the Taijian period, the Sui army carried out a major military campaign. When they heard that Emperor Xuan had died, they ordered the army to return and sent an envoy to offer condolences, using the etiquette of an equal state, and wrote a letter in which they bowed their heads and used their names, and Emperor Gaozu became increasingly arrogant, writing at the end of his letter: I believe that if you properly manage your internal affairs, the universe will be peaceful and stable.
