to let (Quan) Ji have his way, you'll bring disaster upon yourself and your family." Quan Cong ignored Lu Xun's advice and their relationship became strained. When there were rumours that Sun He could no longer secure his position as Crown Prince, Lu Xun wrote a memorial to Sun Quan: "The Crown Prince is the legitimate heir apparent so he should have a foundation as solid as hard rock. The Prince of Lu is a vassal and a subject of the state, so he should receive less favours than the Crown Prince.

In the winter of 251, about half a year before his death, Sun Quan regretted what he did to Lu Xun. When he was sending off Lu Xun's son Lu Kang back to Chaisang (), with tears in his eyes he told Lu Kang, "Previously, I believed slanderous rumours and failed to understand your father's
