After quelling the rebellion of the Seven Kingdoms, Emperor Jing of Han (played by Jiao Huang) set about solving the problem of the kingdoms and reducing the vassal states to strengthen central power. Emperor Jing of Han, who was good at governing the country, followed the Huang-Lao principle of inaction. However, the newly stabilized Western Han Dynasty had to endure humiliation and maintain border security through marriage in the face of the powerful invasion of the Huns. After Emperor Jing's death, the young Emperor Wu of Han, Liu Che, was pushed to the throne under the careful planning and winning over of his scheming mother, Queen Wang. As soon as Emperor Wu of Han ascended the throne, he showed a different spirit and wisdom from previous monarchs, opened up the way for people to speak, sought out wise ministers, and implemented reforms. On the basis of the rule of his father, Emperor Wen and Emperor Jing, Emperor Wu of Han (played by Chen Baoguo) continued to expand the foundation of the Western Han Dynasty, showing the growing imperial spirit in setbacks and difficulties, and with the help of Wei Qing (played by Lu Jianmin), the younger brother of Queen Wei Zifu (played by Lin Jing), he drove the Huns out of the Central Plains after decades of crusade, sweeping away the previous national humiliation. Under Liu Che's iron-fisted rule, the Western Han Dynasty reached an unprecedented heyday.
