After Xi Qingwu, the legitimate daughter of the Xi family, was found from the countryside, she was plotted by her mother, Mrs. Zheng, and her second sister, Xi Qingtong. She was forced to marry Song Yunhe, a poor scholar from a poor family, instead of Xi Qingtong. Xi Qingtong replaced her and became the concubine of the prince Xiao Ji. Xiao Ji ascended the throne and proclaimed himself emperor, and buried the late emperor with lavish burial. Although he cared about his father's death, he still preferred An Wang, and finally chose to let go. At that time, he no longer needed his father's approval. From then on, Xiao Ji and Xi Qingwu worked together to govern the world, neglecting corvee and neglecting taxes, promoting agriculture and focusing on medicine, creating a prosperous age, which became a good story passed down to future generations.
