After the Lü Yi scandal ended in 238, Sun Quan sent a personal representative to meet all his senior generals and apologise to them, as well as to seek their views on how he could reform the bureaucracy to prevent corrupt officials like Lü Yi from abusing their powers again. However, to his disappointment, Zhuge Jin and other generals such as Bu Zhi, Zhu Ran and Lü Dai gave the excuse that they were not in charge of civil affairs and said that civil affairs were best left to civil officials such as Lu Xun and Pan Jun. Sun Quan then wrote an emotional letter to them, blaming himself for the mistakes and urging them to give him honest advice and point out his mistakes. After receiving the letter, Zhuge Jin was so moved that he wrote a clear, detailed and well-reasoned response to the Lü Yi scandal and Sun Quan's queries.
