As the convoy of relocated Nanjing residents passed Pingzhou (near Qinhuangdao) on their way to the Northeast, they persuaded the governor Zhang Jue to restore them to their home town. Zhang Jue, a former Liao official who had surrendered to the Jin dynasty, then switched his allegiance to the Song. The Song Emperor Huizong welcomed his defection, ignoring warnings from his diplomats that the Jurchens would regard the acceptance of defectors as a breach of treaty terms. Zhang Jue was defeated by the Jurchens, and took refuge with Guo Yaoshi at Yanshan. The Song court had Zhang Jue executed to satisfy Jin demands, much to the alarm of Guo Yaoshi and other former Liao officials serving the Song.
