During Murong Hui's and Huang's reigns The future Murong Chui was born in 326, while his father
Murong Huang was still the
heir apparent to
Murong Hui the Duke of Liaodong, a vassal of
Jin dynasty. He was Murong Huang's fifth son. His mother was Consort Lan, a
concubine of Murong Huang. In his youth, he impressed his father with his talent, and he, sometime after succeeding his grandfather as the Duke of Liaodong in 333, wanted to make him the heir apparent. His officials advised against the action (since the general rules of succession requires that the heir apparent be the oldest son of the wife—in this case, his older brother
Murong Jun, the oldest son of
Duchess Duan), and Murong Huang agreed and made Murong Jun heir apparent, but still favored him greatly and officially named him
Murong Ba (慕容霸,
Ba meaning
hegemon). Because of this, Murong Jun was very jealous of his younger brother. Murong Ba became a general for his father early, after his father claimed the title of Prince of Yan and established
Former Yan, although nominally still being a Jin vassal. In 344, for his contribution in the conquest of the
Yuwen tribe, Murong Ba was made the Marquess of Duxiang. Later, Murong Ba was posted to the border with the powerful rival
Later Zhao, whose general Deng Heng (鄧恆) was charged with looking for opportunities to conquer Former Yan, and Murong Ba resisted Deng, causing Deng to be unable to launch a campaign. It was during these years that once, on a hunt, he fell off a horse and lost one of his teeth. After Murong Jun succeeded Murong Huang in 348, because he was still jealous of Murong Ba, he renamed Murong Ba—to
Murong Que (慕容𡙇,
Que means "missing"), but soon found out that
Que is a character signifying fortune in prophecies, and therefore again renamed him to Murong Chui, the name that he would be known later by.
During Murong Jun's reign Soon after Murong Jun succeeded Murong Huang, Later Zhao collapsed after the death of Shi Hu, as Shi Hu's sons and adoptive grandson
Shi Min (who later changed his family name back to his father's original "Ran") engaged in a destructive struggle. Despite the turmoil, Murong Jun was initially hesitant to march south to take over Later Zhao territory, but Murong Chui convinced him that the opportunity was ripe. With Murong Chui as a major generals, Murong Jun advanced south and, after capturing and executing
Ran Min in 352, took over the eastern half of former Later Zhao territory. During the next few years, Murong Chui participated in subduing many former Later Zhao generals who were still semi-independent. In the winter of 352, Murong Jun formally declared himself independent from the Jin, as emperor, and in 354, when making titles for many of his sons, brothers, and uncles princes, he made Murong Chui the Prince of Wu. However, Murong Jun continued to be jealous of Murong Chui's talents. He briefly made Murong Chui the defender of the important city and former capital Longcheng (龍城, in modern
Jinzhou,
Liaoning), but after it became clear that Murong Chui was ruling the region successfully and garnered the support of the people, Murong Jun became fearful and recalled him to the new capital Yecheng (鄴城, in modern
Handan,
Hebei). In 358, Murong Chui would lose his wife
Princess Duan to political intrigue. Princess Duan, being the daughter of
Duan Mobo and therefore derived from the royal family of
Duan tribe, was proud of her bloodline and disrespectful to Murong Jun's wife
Empress Kezuhun. Perhaps at Empress Kezuhun's instigation, the
eunuch Nie Hao (涅浩) falsely accused Princess Duan of
witchcraft. Murong Jun had her and her alleged coconspirator, Murong Chui's assistant Gao Bi (高弼), arrested. Princess Duan and Gao were tortured, but they refused to admit the charges of witchcraft, and because of this the torture was intensified. Murong Chui was saddened by his wife's suffering, and he sent her a message trying to persuade her to end her suffering by admitting to the charge (and thus end the torture but be sentenced to death). Princess Duan remarked: I am not fearful of death. However, if I falsely implicate myself, I admit to treason. I would be betraying my ancestors and dragging Your Royal Highness into this disaster. The results are dire, and I will not do this. As she was interrogated, Princess Duan replied logically and openly, and Murong Chui was able to avoid being dragged into the case, but she still died in prison, either from the torture or a secret execution. Murong Chui then married her sister as his new princess. However, after a brief time, Empress Kezuhun ordered that the new Princess Duan be deposed, and she married her sister, the Lady of Chang'an, to Murong Chui as his new princess. Murong Chui did not dare to refuse, but he was displeased, and Empress Kezuhun became even more resentful of him. Because of this, Murong Chui was briefly effectively exiled to be the governor of remote Ping Province (平州, modern eastern
Liaoning). He was only recalled when Murong Jun became ill in 359. In 360, Murong Jun died. He was succeeded by his son and crown prince
Murong Wei, with Murong Jun's younger brother and Murong Chui's older brother
Murong Ke, Prince of Taiyuan as
regent.
During Murong Wei's reign During Murong Ke's regency Unlike Murong Jun, Murong Ke trusted Murong Chui and consulted him on many decisions—including what to do with
Muyu Gen when Muyu Gen conspired against him in 360. Later that year, he sent Murong Chui to pacify southern provinces which became disturbant in light of Murong Jun's death. In 365, he assisted Murong Ke in capturing the important Jin city of
Luoyang, and after doing so became the commander of the southern armies, defending against possible Jin counterattacks. In 367, Murong Ke grew ill, and on his deathbed he advised Murong Wei to let Murong Chui succeed him. He also tried to convince Murong Wei's older brother Murong Zang (慕容臧), Prince of Le'an and his own uncle and co-regent
Murong Ping (慕容評), Prince of Shangyong of the wisdom of giving at least the post of commander of the armies to Murong Chui. However, after Murong Ke's death later that year, Murong Ping and Empress Dowager Kezuhun disagreed with his advice, and Murong Ping became regent while the commander of the armies post was given to Murong Wei's brother
Murong Chong, Prince of Zhongshan.
During Murong Ping's regency Neither Murong Ping nor Empress Dowager Kezuhun trusted Murong Chui, and he was not given important responsibilities. In 368, when four dukes of the rival
Former Qin rebelled against its emperor
Fu Jian, Murong Chui was one of the advocates for assisting the four dukes, who sought Former Yan assistance, and further taking the opportunity to conquer Former Qin. However, Murong Ping declined to do so, and Former Qin captured and executed the four dukes. In 369, the Jin general
Huan Wen launched a major attack against Former Yan, defeating each Former Yan army sent against him and advancing all the way to Fangtou (枋頭, in modern
Hebi,
Henan), near Yecheng. Murong Wei and Murong Ping panicked and considered fleeing to the former capital Longcheng. However, Murong Chui volunteered to make one last stand against Huan Wen, and he and his brother
Murong De dealt Huan a major defeat. Relief forces from Former Qin (which Former Yan requested) then arrived, and together they dealt Huan another major defeat, ending Huan's hopes of destroying Former Yan. However, both Murong Ping and Empress Kezuhun grew even more jealous of Murong Chui after his victory and denied his soldiers the rewards that he requested. Murong Ping and Empress Kezuhun further considered executing him. Murong Ke's son Murong Kai (慕容楷) and Murong Chui's uncle Lan Jian (蘭建) suggested that he start a coup, but Murong Chui declined. Instead, he accepted his
heir apparent Murong Ling's (慕容令) suggestion, seeking to flee and take over Longcheng to try to force reconciliation with the imperial government. Murong Chui put his plan in motion in the winter of 369. However, once he left Yecheng, his son
Murong Lin, whom he had not favored, fled back to Yecheng to report on him, and Murong Ping sent an army to chase after him. Murong Chui then changed his plan and sought to flee to Former Qin instead. He then scattered his followers and fled back south. On the way, another son Murong Manu (慕容馬奴) wanted to flee back to Yecheng and was killed by him. When he was stopped at the
Yellow River, he killed the commander of the guards stopping him, forcing his way to Luoyang, and then fled to Former Qin with the younger Princess Duan, Murong Kai, Lan Jian, Gao Bi and his sons Murong Ling,
Murong Bao,
Murong Nong, and
Murong Long. Princess Kezuhun remained at Yecheng. == During Former Qin ==
