According to Mencius, though Song was a small state, he was setting about to practise the "true royal government" (王政).

In 286 BC, King Min of Qi plotted with the states of Chu and Wei for a joint expedition against Song, Yan fled to Wei and died there. Finally, Song was partitioned by Qi, Chu and Wei.
