This is a controversial issue, because every dynasty has its periods of prosperity and decline. But according to the research of historians and scholars, one of the most prosperous dynasties in China's history was the Tang Dynasty (6 18-907). The Tang Dynasty made great progress in economy, culture and science and technology, and was called "the pinnacle of Chinese civilization". During the Tang Dynasty, China's national strength and culture reached its peak. At the same time, the prosperity of the ancient Silk Road trade, abundant food and clothing, the prosperity of artistic works and the prevalence of poetry creation all proved the prosperity of the Tang Dynasty. However, other historical periods also have their own characteristics of prosperity, such as Han Dynasty, Yuan Dynasty and Ming Dynasty. Every dynasty has its unique highlights and contributions, and we can't just see prosperity, nor can we ignore other aspects of history.
