Yan Hongliang, the king of Hailing, used all the troops of Xu Jinguo, and divided the troops into four ways, preparing to destroy the Song Dynasty in one fell swoop. The battle of Caizhou took place in the middle of the attack of nomads from Shanxi Province. The commander-in-chief of the nomads from this road was Liu E, and the middle road was unimpeded, breaking through the defense line of the Song Dynasty in one fell swoop and entering the city's offensive and defensive warfare.
At this time, the Song Dynasty sent a team of cavalry to cut off Liu's retreat and prepare to attack Liu's army before and after, and the commander of this cavalry was Zhao Zun. When Zhao Zun cut off Liu Hou Road, he found that Cai Zhou was empty, and Zhao Zun took the opportunity to win Cai Zhou. The war ahead was tight, and Zhao Zun had to go to support. As a result, Cai Zhoucheng was recaptured by the nomads from the army. Zhao Zun had to lead the troops back to Cai Zhou and take Cai Zhou back.
There was a coup inside the ruler, and Yan Hongliang was killed by his mutiny. The Jin army was forced to retreat, and Caizhou City was the only way for the Jin army to go back, so a protracted battle took place in Caizhou City.
Nomads from the forces far exceed Zhao Zun's forces. 8 Jin Jun attacked Cai Zhou with a wheel war, and even once captured Cai Zhou, but Zhao Zun organized Cai Zhou soldiers and civilians to launch wave after wave of counterattacks, which drove Jin Jun to the extreme, and the support of the Song Dynasty was on the way. Moreover, the 8 Jin Army constantly strengthened its strength, and the Song Dynasty also sent troops to support it. Under such circumstances, Zhao Zun launched a three-month offensive and defensive war with Jin Jun in Caizhou City, but Jin Jun made no progress. Finally, under the active withdrawal of the Song Dynasty, Cai Zhou returned to the hands of the Jin people, who were able to return to China.
