《资治通鉴·汉纪·汉纪四十五》
宋亮到任以后，开导和招募于阗人，命他们自己斩杀输。这时，输已经死了一个月，于是他们将死人的头砍下，送到敦煌郡太守府，但没有说斩杀的具体情况。宋亮后来才知道其中有诈，但到底不能再出兵讨伐。
亮到，开募于窴，令自斩输僰；时输僰死已经月，乃断死人头送敦煌而不言其状，亮后知其诈，而竟不能讨也。
After Song Liang was in position, he came to an understanding with the people of Yu Tian and recruited them, ordering them to kill Shu themselves. By this time, Shu had been dead for a month, so they cut off his dead head and sent it to the Governor's Office of Dunhuang, but they did not disclose the details of his death. Song Liang learned of the deceit later on, but could not send troops to quell it after all.
