Even Gu Yi couldn't describe what kind of prosperous reign this was.
As a modern person.
Especially as a modern person who has read many history books, although Gu Yi could not achieve omniscience of history, he was generally aware of what the prosperous times and turbulent periods in the original history were like.
In the original history—
The so-called "Reign of Wen and Jing," "Kaiyuan's Flourishing Era," "Reign of Ren and Xuan," and even the later "Kang and Qian's Flourishing Era," had similar cores.
—that is, after experiencing chaos or decline, the court implemented relatively lenient policies, reduced corvée and lightened taxes, allowed the people to rest, and agricultural productivity was restored and developed, the population grew, the treasury was full, and society was stable.
The common people could eat their fill, dress warmly, and stay away from large-scale chaos and harsh governance, which could be called a "prosperous time."
