About Xue Song

Xue Song, formally the Prince of Pingyang (平陽王), was a general of the Chinese rebel state Yan, who later submitted to and became a general of the Tang dynasty, from which Yan had rebelled. As was in the case of several other Yan generals who submitted to Tang but who had substantial army and territorial holdings, Xue was allowed to retain his command and territory, semi-independent of the Tang imperial government structure.
