Wang Jizhong was a Song general but agreed to serve the Liao after he was captured and offered a high position. According to the Liao History, after he became a Liao general, the Song Government gave him gifts every time an envoy came from the south to the Liao. This was known to the Liao emperors. Although he was a former Song officer, he was allowed to accept them. Liao shi, p. 1284.
