In 950, after Ma Xi'e was able to persuade Ma Xiguang's general Xu Keqiong into defecting and surrendering Changsha to him, Changsha fell, leading to a general pillaging of the capital city. The officer Lu Mengjun (), who had long despised the Yangs, used this opportunity to attack the Yangs' mansion and slaughter them. However, it was said that Lady Yang's fate, after the slaughter, was unknown.
