Li Jing'ai is the daughter of Li Huan, the first monarch of Xiliang, and is beautiful and moving. When Northern Liang attacked Western Liang, the prince of Northern Liang, Frustrated Canal Mu Qian, made a great contribution, and soon after saw Li Jing'ai, he was attracted to her, and after asking his father to marry her, his father Frustrated Qu Mengxun reluctantly gave her to his son after hearing this.
Soon after, Li Jing'ai was made a concubine, and after ascending to the throne, he made her queen, but in the end he empathized with Tuoba Tao's sister and moved Li Jing'ai and her mother Yin shi to Jiuquan, where Li Jing'ai was depressed and died soon after arriving at Jiuquan. Just after Tuoba Tao's sister became queen, Frustrated Qu Muqian superficially respected her, but in fact did not feel anything, and when he was depressed, he met another woman, this person was his sister-in-law Li Shi.
It is said that this woman looked feminine and charming, born with special things, and soon, Depressed Canal Mu Qian hooked up with this sister-in-law, Li Shi; soon made Depressed Qu Mu Qian fascinated. What was even more unexpected was that his two brothers, Frustrated Canal Wuxia and Frustrated Canal An Zhou, were actually on good terms with Li Shi, and in the face of this situation, the three brothers were not afraid, and the matter was quickly spread. In order to compete for favors, Li sent someone to poison Princess Wuwei (Tuoba Tao's daughter) to cause Tuoba Tao's anger, and he quickly aimed his spearhead at Mu Qian, and ordered him to hand over Li Shi.
Frustrated with Li Shi, Mu Qian became obsessed with Li Shi and angrily rebuked Northern Wei's domineering. However, in the end, he gave Li a large amount of money, moved her to Jiuquan, hid her, and Princess Wuwei returned to Northern Wei. These things are found in the Book of Wei and the History of the North, but in the Spring and Autumn of the Sixteen Kingdoms and the Book of Song, Mu Qian became a diligent and studious gentleman. In 439, Northern Wei sent troops to attack Muqian in The Depression Canal.
In September of the same year, Mu Qian of The Depression Canal bound himself and led more than 5,000 civil and military officials out of the city to surrender, and Northern Liang was destroyed. However, after The Frustrated Canal Muqian arrived in Northern Wei, Tuoba Tao still regarded him as a brother-in-law; but the good times were short-lived, and in 447, someone reported that the Depressed Canal Muqian family had a large number of rare treasures hidden in his home, intending to plot against him, and soon he was killed by Tuoba Tao, who said goodbye to Princess Wuwei and committed suicide after wandering for a long time. After the death of Princess Wuwei, Tuoba Tao issued an edict to bury the husband and wife together.
