The general idea is that Wang Zhaojun went out to humiliate the country and the court humiliated the country and made peace. From then on, the Western Han Dynasty began to decline and the world was depressed.
At present, most of the works about Zhaojun's leaving the fortress describe Zhaojun's leaving the fortress as the Xiongnu being strong and the Han being weak, and the court humiliating peace and then attacking the Han emperor. In fact, this is inconsistent with the official history. From the Western Han Dynasty to the early Yuan Dynasty, the story of Zhaojun's leaving the fortress experienced an evolutionary process. It was first seen in Yuan Di Ji and Xiongnu Biography in Han Dynasty. The general plot is as follows: In the first year of Jingning in the Western Han Dynasty (33 BC), Yuan Di took Wang Qiang, the imperial secretary, and Zhao Jun entered the Xiongnu and gave birth to two sons, calling Han Ye a dead man. When he became emperor, he was restored as Khan E Shi. In Yuan Di, the Han Dynasty was stronger than the Huns, which was the concrete embodiment of Yuan Di's policy of national harmony.
