In the first month of the 11th year of Taiyuan (386), Teng Tianzhi attacked Minglu City in the south, and Zhai Liao shut the gate behind him and refused to let him return. Teng Tianzhi fled eastward to Juancheng, where Zhai Liao pursued and captured him, so he occupied Liyang. Zhu Xu sent generals from Yuzhou, Qin Ying and Tong Bin, to crusade against Zhai Liao in the counties of Huaihe River and Surabaya. In March, Bird, the satrap of Mount Tai in the Eastern Jin Dynasty, led the county to rebel from the Eastern Jin Dynasty and fell to Zhai Liao. In August, Zhai Liao invaded Qiao County in the Eastern Jin Dynasty and was repelled by Zhu Xu, the secretariat of Yuzhou. In the twelfth year of Taiyuan (387), in the first month, Zhai Liao sent his son Zhai Zhaojin to invade Chenliu and Yingchuan counties in the Eastern Jin Dynasty. Zhu Xu sent general Qin Ying to repel Zhai Zhao. In April, Zhai Chang, a Gaoping man, took the magistrate Xu Hanyuan and led the people of the county to surrender to Zhai Liang. Later Emperor Cheng said to the generals: "Zhai Liao only relied on the department of one city and repeatedly rebelled among the three countries, so he had to crusade." In May, Zhang Mu Rongchui was ordered to supervise Chinese and foreign military affairs and assist Prince Murong Bao in guarding the capital Zhongshan; Mu Rongchui led the generals south to attack ZhaiLiao. He appointed Murong Kai, the king of Taiyuan, as the commander-in-chief of the striker. Everyone in the stockade is Zhao Yan. When they heard that Murong Kai came with an army, they all said, "The son of King Taiyuan is our parents!" So they all led each other to surrender to Murong Kai. Zhai Liao was very afraid, so he sent messengers to see Hou Yan's army and demanded surrender. Mu Rongchui appointed Zhai Liao as Xuzhou Pastoral, made him the Duke of Yuzhou, and went to Liyang. In October, Zhai Liao rebelled against Hou Yan again, and sent troops to cooperate with Wang Zu and Zhang Shen's army to burn, kill and plunder in Qinghe Plain.
In the 13th year of Taiyuan (388), in March, Zhai Liao sent Sima Ziqiong to Houyan to apologize and surrender because he was afraid of Houyan's soldiers. Mu Rongchui beheaded Qiong Qi because of his willfulness and refused his request. Therefore, Zhai Liao called himself Wang Wei, changed his name to Jianguang, set up 100 civil and military officials, and established Zhai Wei's political power. In May of the same year, Zhai Liao moved the capital to slide platform (now hua county, Henan). In April 389, the second year of Jianguang, Zhai attacked Xingyang and captured Zhang Zhuo, the satrap of Xingyang. In October, after Yan mourned Wang Murong Wen's appointment as the secretariat of Jizhou, Zhai Liao sent his subordinate Ding Ling to the levee and surrendered under Murong Wen's account. On the fourth day of October, the dike assassinated Murong Wen and his long history Sima Qu and seized Jizhou.
After Zhai Liao captured Jizhou, he repeatedly attacked the southern part of the Eastern Jin Dynasty. In the third year of Jianguang (390), Zhu Xu, a general of the Eastern Jin Dynasty, tried to attack the Emperor Murong Yong of Xiyan jointly with Zhai Liao. However, Zhu Xu was furious and decided to take refuge in ZhaiLiao. He ordered Liu Laozhi, a famous soldier in the northern government, to capture Zhencheng, defeat ZhaiZhao, the son of ZhaiLiao, and then attack the slipway, and defeated ZhaiLiao. Since then, Zhai Wei has never recovered.
In October of the fourth year of Jianguang (39 1), Zhai Liao died, and Zhai Zhao, the son of Zhai Liao, succeeded to the throne, and changed his country name to Dingding. After Zhai Zhao succeeded to the throne, he immediately attacked Yecheng of Houyan and was defeated by Murong Nong, the king of Liaoxi, Houyan. On the fifth day of February in the second year of Dingding (392), Emperor Mu Rongchui of Houyan set out from Lukou to Hejian, Bohai Sea and Plain. Zhai Zhao sent Zhaidu to invade Guantao and stationed in the Soviet Union. In March, he led the army south to attack Zhaizhao, which matched Su. In April, Zhaidu retreated south to the sliding platform. Zhai Zhao turned to Xi Yan for help.
In June of the second year of Dingding (392), Mu Rongchui's troops arrived in Liyang (now Xunxian County, Henan Province) and came to the bank of the Yellow River to prepare to cross the river. Zhai Zhao deployed troops on the south bank of the Yellow River to resist the army of Hou Yan. On June 16th, Mu Rongchui moved the camp to the Western Jin Dynasty, 40 miles away from Liyang, built more than 100 cowhide warships, pretended to be loaded with soldiers' equipment and swam against the current. Zhai Zhao hurriedly led the troops to attack the western Jin defense. Also secretly sent generals, Wang Murong Town and others to cross the river from Liyang Ferry overnight and camp on the south bank of the Yellow River. At dawn, Houyan's camp has been completely built. When Zhai Zhao heard the news, he hurried back and attacked the barracks of Murong Town and others. Mu Rongchui ordered Murong Town to stand guard and not to fight. Zhai Zhao's soldiers and horses were so tired and hot that it was difficult to win the camp of Hou Yan's army. He is preparing to retreat with his troops. Murong Town and others suddenly rushed out of the camp. At the same time, Murong Nong, a general of Hou Yan's title of generals in ancient times, crossed the Yellow River from the Western Jin Dynasty and attacked Zhai Zhao with Murong Zhen and others, which was a great defeat. Zhai Zhao fled back to the sliding platform, took his wife and children, gathered the defeated troops, crossed the Yellow River to the north and climbed Bailu Mountain. Relying on the steep mountain, Hou Yan's troops could not attack. Murong Nong said: "Zhai Zhao must not curl up in the mountains for a long time without food." He led his troops back to the camp, leaving only some cavalry waiting for Zhai Zhao's action. Zhai Zhao really came down from the mountain, and Murong Nong immediately returned to the army to surprise and captured Zhai Zhaoquan's troops. Only Zhai Zhao rode his eldest son to Xiyan Capital (now Zhangzi County, Shanxi Province) and surrendered to Xiyan, and Zhai Wei's political power perished. Murong Yong, the emperor of Xiyan, appointed Zhai Zhao as a chariot-riding general and Yanzhou shepherd, and made him the king of East County. More than a year later, Zhai Zhaomi rebelled against Xiyan and was killed by Murong Yong.
