When was the most prosperous time in history?

Historians have had a public opinion since ancient times. Those who can be called prosperous times must meet six criteria, namely, national prosperity, people's safety, national prosperity, people's prosperity, national strength and Wenchang. These six criteria are the criteria for judging the prosperous times. The following are five periods known as the prosperous times of China.

Zhao Xuan and Shi Sheng in the Western Han Dynasty

Zhang Ming and Shi Sheng in Eastern Han Dynasty

The Sui Dynasty opened the golden age of emperors.

Kaiyuan Shi Sheng in Tang Dynasty

Yongle Shi Sheng in Ming Dynasty

PS: There are many prosperous times in the history of China, but many prosperous times are not the state of national unity. The real prosperous time is the period when the comprehensive national strength of the unified country is the strongest. The above five prosperous times are the most brilliant. The prosperous times of other unified dynasties, such as the rule of Wenjing and the revival of martial arts, are all in a state of accumulating strength. Zhenguan rule, political clarity but not the peak of national strength in Tang Dynasty. Renzong's rule is not unified, and Ren Xuan's rule is the continuation of Yongle.
