 When the Song dynasty reclaimed the southern part of the Liao where Han Chinese lived, they were "fiercely resisted" by the Han Chinese population there who had previously been under Liao rule, while when the Jurchens invaded that area, the Han Chinese did not oppose them at all and handed over the Southern Capital (present-day Beijing, then known as Yanjing) to them.The Jurchens were supported by the anti-Song, Beijing-based noble Han clans.The Han Chinese who worked for the Liao were viewed as hostile enemies by the Song dynasty.
