The story takes place in a historical period. After Liu Bang proclaimed himself emperor, he created the Great Han Dynasty. Emperor Hui, but Lu Zhi, who was determined to control the political power, was strong and decisive in the court, and Liu Bang's previous Mrs. Qi, the favorite concubine, and her son were all killed. He also forced Liu Ying to marry his niece Zhang Yan as queen. As a result, Liu Ying was depressed all day long, and died 7 years later

Lu Zhi's rights have become more inflated, dividing up the rights of the Liu clan. After Lu Zhi's death, in order to consolidate the Han Dynasty, Liu Heng, who was far away in the frontier, succeeded to the throne as Emperor Wen of Han. Emperor Wen of the Han Dynasty, Liu Heng, always advocated frugality, diligent government and caring for the people, and the name of benevolence was widely spread. During his 23 years in power, he abolished many unreasonable tortures and encouraged people to farm. He was also the first emperor in all dynasties to exempt land rent. He has always insisted on making peace, and has always maintained a stable policy towards the Xiongnu, so that he can protect the Han Dynasty. However, Emperor Hanwen had been exhausted physically and mentally for a long time, leading to his death at the age of 46. From then on, it was Liu Qi who inherited the emperor's career, and started a new period of rule, which was also called the rule of Wenjing by everyone. After Liu Qi passed away, Emperor Wu of the Han Dynasty Liu Che continued to lead the Han Dynasty to prosperity.
