The specific analysis is as follows:
First, Emperor Wendi and Emperor Jingdi recuperated, and the national strength reached its peak during the period of Emperor Wudi of the Han Dynasty.
After Liu Bang's death, Lv Zhi monopolized the power, which did some damage to the Liu family. Emperor Wen of Han Dynasty and Emperor Jing of Han Dynasty began to attach importance to economic development and implemented the policy of rest and recuperation, which promoted the economic development of Han Dynasty and created cultural landscape. In view of this, the two emperors became good emperors in the eyes of the people. People tend to remember the brightest one. During the period of Emperor Wu of the Han Dynasty, after the party's recuperation, the national strength reached its peak, and people had a deeper memory of Emperor Wu of the Han Dynasty, which was logical.
Second, Emperor Wendi and Emperor Jingdi advocated the technique of Huang Lao, while Emperor Wudi of the Han Dynasty ousted hundreds of schools of thought and respected Confucianism alone.
We judge a historical figure according to his description in the history books. As we know, since Emperor Wu of the Han Dynasty adopted Dong Zhongshu's suggestion of "ousting a hundred schools of thought and respecting Confucianism alone", Confucianism founded by Confucius became the orthodox thought of feudal society, while the historical position of Huang Lao's skill advocated by Emperor Wen and Emperor Jing of the Han Dynasty in social thought was diluted. Comparatively speaking, the descendants and disciples of Confucianism pay more attention to the political environment provided by Emperor Wu of Han Dynasty, and it is understandable that they respect Emperor Wu of Han Dynasty.
Third, Wendi Jingdi's foreign policy was conservative, while Emperor Wudi of the Han Dynasty attacked Xiongnu in the north and made outstanding achievements.
During the period of Emperor Wendi and Emperor Jingdi, the economy was ruined and the foreign policy was conservative. There are not many records about the wars between Wendi, Hanjing and Xiongnu, but many policies are adopted. During the period of Emperor Wu of the Han Dynasty, military commanders Wei Qing and Huo Qubing were reused to attack Xiongnu in the north, which made great contributions in the history of the Han Dynasty. In addition, through the pacification of consanguinity, the management security of the country was effectively maintained, which made greater contributions to the history of China.
