伪青、齐节度能元皓独率众归顺，明年，改乾元元年，伪德州刺史王暕、贝州刺史宇文宽等皆归顺，河北诸军各以城守累月，贼使蔡希德、安太清急击，复陷于贼，虏之以归，脔食其肉。
An Qingxu's court's Qingzhou and Qizhou regional commanders Can Yuanhao led their troops and surrendered to the Tang court. The following year, the Tang court changed the reign title to the first year of Su Zong's Qianyuan, and An Qingxu's court's Dezhou magistrate Wang Riqian and Beizhou magistrate Yuwen Kuan surrendered to the Tang court. The troops in various towns in Hebei had defended the cities for many months, and An Qingxu's court ordered Cai Xide and An Taiqing to attack fiercely, and were conquered by the rebel army again. The captured soldiers were chopped into pieces for food.
