At the beginning of his reign, Li also took many measures to promote the development of the later Tang Dynasty, but with the growth of his reign, he began to indulge in pleasure. At the same time, he indulged the harem politically and killed the meritorious minister at will. His behavior caused some North Korean officials and civilians to become increasingly dissatisfied with him, and the last one, Guo, launched a mutiny. Li died in the mutiny, and many of his concubines also fled the palace in succession. Chai is one of them.
After leaving the palace, Chai returned home. One day, she happened to see a man passing by her door, very distinguished, so she fell in love with him secretly. So she asked around about this man's identity, and finally realized that this man's name was Guo Wei, just a beggar who couldn't keep enough food and clothing. But Chai did not give up his love for Guo Wei because of his identity, but insisted on marrying him. At her insistence, her parents can only promise this marriage.
With the help of Chai, Guo Wei began to accumulate his power bit by bit. With his own ability and power, he first helped Liu Zhiyuan to establish the Later Han Dynasty, then launched a mutiny to overthrow the Later Han Dynasty after further accumulating power, and established the regime of the Later Zhou Dynasty. After he became emperor, he made Chai, who had been helping him behind his back, a queen. Even after Chai died, he never set up a queen again.
