Sixteen Prefectures
Meanwhile, the eastern army, commanded by Wanyan Zongwang, was dispatched towards Yanjing (modern Beijing) and eventually the Song capital Kaifeng. It did not face much armed opposition. Zongwang easily took Yanjing, where Song general and former Liao governor Guo Yaoshi () switched his allegiances to the Jin. When the Song had tried to reclaim the Sixteen Prefectures, they had faced fierce resistance from the Han Chinese population, yet when the Jurchens invaded that area, the Han Chinese did not oppose them at all. By the end of December 1125, the Jin army had seized control of two prefectures and re-established Jurchen rule over the Sixteen Prefectures. The eastern army was nearing Kaifeng by early 1126.
