This can't be compared like this. Every dynasty has its own glorious period, and benefiting the country and the people is the biggest in this period. During the Tang Dynasty, the rule of Zhenguan, the rule of Yonghui and the prosperity of Kaiyuan were all brilliant. The Tang Dynasty is the largest and only unified Central Plains dynasty without the Great Wall, allowing Nanzhao, Silla, Bohai and Japan to learn their own culture and system. By the Tang Dynasty, science, technology, culture, economy and art were diversified, and a large number of famous artists emerged in poems, books and paintings, and they accepted exchanges and studies from people from all over the world, forming an open international culture. The Tang Dynasty and the Arab Empire were the most powerful empires in the world at that time, and their reputation spread far and wide overseas, and they had contacts with Asian and European countries. After the Tang Dynasty, China was called the Tang Dynasty overseas.

Song Dynasty was a period of high prosperity in commodity economy, culture, education and scientific and technological innovation in the history of China. At that time, China's GDP totaled US$ 26.55 billion, accounting for 22.7% of the world economy, and its per capita GDP was US$ 450, exceeding the US$ 400 in Western Europe at that time. Although later generations thought that the Song Dynasty was "poor and weak", the people's wealth and social and economic prosperity in the Song Dynasty far exceeded that in the prosperous Tang Dynasty. Neo-Confucianism rose in Song Dynasty, Confucianism revived, science and technology developed rapidly, politics was enlightened, there was no serious eunuch dictatorship and warlord regime, and the number and scale of mutiny and civil strife were relatively small in China history. The Song Dynasty was founded more than 300 years ago and was overthrown twice, both because of foreign invasion. This is the only dynasty that did not die of civil strife.

In the Yuan Dynasty, the territory of the whole country was the largest, and the local provincial system was the first in the country. Culturally, Yuan Qu, Sanqu and other cultural forms appeared in this period.

The Ming Dynasty was the last unified dynasty established by the Han nationality in the history of China. In the Ming Dynasty, handicrafts and commodity economy flourished, commercial market towns and capitalism sprouted, and culture and art showed a trend of secularization. Ming Dynasty has a large population and developed commodity economy, which is the golden age after Han and Tang Dynasties.

The Qing Dynasty was the last unified feudal dynasty in the history of China. Kang Yong's three dynasties reached their peak. During this period, all aspects of China society reached the acme under the original institutional framework, with the greatest reform, the strongest national strength, social stability, rapid economic development, rapid population growth and vast territory. The unified multi-ethnic country was consolidated, and the rulers of the Qing Dynasty incorporated Xinjiang and Tibet into the territory and implemented the policy of changing soil into water in the southwest. Finally, the territory of modern China was determined, and the integrity of the country's territorial sovereignty was actively safeguarded. But it also pushed feudal autocracy to the highest peak. In the middle and late period, due to political rigidity, cultural autocracy, closed door, ideological imprisonment, scientific and technological stagnation and other factors, it gradually fell behind the West. Eventually perish.
