《资治通鉴·汉纪·汉纪二十四》
王立因此上密封奏书，请求成帝把淳于长留在京师。他说： 陛下既然在诏书中说因皇太后的缘故不加罪淳于长，就实在不应该再有其他惩罚。 
立因上封事，为长求留，曰： 陛下既托文以皇太后故，诚不可更有它计。 
Wang Li therefore submitted a sealed memorial, requesting that Emperor Cheng keep Chunyu Chang in the capital. He said: "Since Your Majesty said in the imperial edict that you would not punish Chunyu Chang in consideration of the Empress Dowager, then you should not have punished him at all."
