宋刘 / Song Liu
宋刘 / Song Liu enters the wiki through Qinji 129-4 as a 陈胜-sent commander who had taken 南阳郡 and moved toward Wu Pass before Chen Sheng’s death. Once Chen Sheng’s death spreads, the episode says morale collapses, Nanyang returns to Qin, and Song Liu surrenders.
胡亥 / 秦二世 responds by ordering Song Liu torn apart by chariots. The source treats the punishment as politically self-defeating: if a surrenderer is publicly killed, later rebels have less reason to surrender and more reason to fight on.
Song Liu therefore anchors 杀降纳降反噬 inside the Qin-collapse branch. His page records the episode’s policy reading, not an independent claim that Qin’s later failures can be reduced to this single execution.
