《资治通鉴·隋纪·隋纪四》
杨谅因为这些人是他过去的老部下，奏请文帝留下这些人。文帝发怒说： 你作为藩王，只应恭敬地遵从朝廷的命令，怎么可以因私而谈论宿旧，废弃国家的法令呢！
谅以其宿旧，奏请留之，高祖怒曰： 尔为籓王，惟当敬依朝命，何得私论宿旧，废国家宪法邪！
Yang Liang pleaded with Emperor Wen to keep these people because they were his former subordinates. Emperor Wen was angry and said: As a vassal king, you should only respectfully obey the orders of the court, how can you discuss the old people and abandon the laws of the state for your own sake!
