In China, 408 emperors were born in five thousand years. So who can be called the "one emperor through the ages"?
The issue of one emperor through the ages has been debated for a long time, but no conclusion has been reached. It can be said that there are many people who can be called one emperor through the ages, such as: Qin Shihuang Ying Zheng, Emperor Wu of Han Liu Che, Tang Taizong Li Shimin, Song Taizu Zhao Kuangyin, Yuan Taizu Genghis Khan , Qing Shizu Kangxi, etc.
Of course, their achievements are not decided by themselves, but later generations make objective evaluations of their contributions based on objective history. Similarly, the achievements and actions of ancient emperors can only be known from historical records, and conclusions can only be drawn by comparison with each other.

1, Qin Shihuang, relied on his very strong strategy and willpower to develop Qin State step by step through reforms, and then successively annexed the other six countries within a period of time to unify the country. Cultural unification has played a great role in promoting the further integration of the Chinese nation to a certain extent. It has also unified currencies and weights and measures economically, allowing the currencies and economies between countries to fully operate. Since the beginning of the Qin Dynasty, he has unified the dynasty, unified literature, weights and measures, coins, and roads, created the system of prefectures and counties, and centralized power. His contribution can be said to span the ages, and he is worthy of his name as one emperor through the ages.

2, Emperor Wu of Han Dynasty Liu Che, the most outstanding statesman, strategist and poet in Chinese history. During his reign, China and North Korea were established, governors were established, inspection and promotion systems were established, and the power of salt, iron and coinage was returned to the central government; culturally, "hundreds of schools of thought were deposed, and Confucianism was the only one respected"; militarily, the barbarians were expelled, the territory was expanded, and the country's prestige was far-reaching, and North Korea was merged in the east and North Korea was annexed in the south. The Baiyue , the westward expedition to Dayuan, and the northern defeat of the Xiongnu established the basic scope of the Han Dynasty and created the Han Dynasty. He also made achievements in various fields such as opening up the Silk Road, establishing the reign title, issuing the Taichu Calendar, and promoting Taixue. Emperor Wu of the Han Dynasty is an important reason why we are called Han people. This is a symbol of a great clan. One emperor must have his own status throughout the ages.

3, Tang Taizong Li Shimin, an outstanding politician, strategist, military strategist, and poet in Chinese history, made great achievements in the establishment and unification of the Tang Dynasty. He launched the Xuanwumen Revolution, killing his elder brother Li Jiancheng and his fourth brother Li Yuanji, and forced Li Yuan, Emperor Gaozu of the Tang Dynasty, to retreat. Li Shimin listened to the opinions of the ministers, governed the world internally, accepted advice humbly, practiced economy, and encouraged people to farm and mulberry, so that the people could recuperate, the country was peaceful and the people were safe, and he created the famous Zhenguan rule. Expanding territory, exterminating the Eastern Turks and Xue Yantuo, conquering Gaochang, Qiuci, and Tuyuhun, inflicting heavy losses on Goguryeo, and establishing four towns in Anxi. All ethnic groups lived in harmony, laying an important foundation for the prosperity of the Tang Dynasty for more than a hundred years. The culture and ideas of the Chinese people reached the pinnacle of the world to a certain extent, forming a grand scene from all nations to Korea. It is understandable that he is called the emperor of the ages.

4, Song Taizu Zhao Kuangyin's greatest contribution and achievement in his life was to restore the unification of the Huaxia region, ending the 200-year feudal separatism and warlord wars since the An-Shi Rebellion. The war-torn people finally had a peaceful production and living environment, creating good conditions for social progress, economic development, and cultural prosperity.

5, Genghis Khan, the ancestor of the Yuan Dynasty, created many brilliance and extremes in human history. He was called the "genius of the generation" by later generations. Especially in the development of strong territory, he was unprecedented and unprecedented. It created the largest empire in the world and unified the Mongolian grassland. More than 40 countries and more than 700 ethnic groups were affiliated with the Mongolian Empire. It established a huge dynasty with a vast territory, the Steppe Empire, also known as the Continental Empire. Its territory was unprecedented and unprecedented. According to relevant historical records, the mainland at that time exceeded It covers an area of more than 20 million square kilometers, including basically all of Siberia and the entire territory of present-day China, which is three times the current territory of China.

6. Kangxi, the holy ancestor of the Qing Dynasty, the Qing Dynasty was a country ruled by ethnic minorities. The fundamental reason why it was able to enter the Central Plains was that there was a great civil strife in China at the end of the Ming Dynasty. The Manchus succeeded in passing through Confucius. Kangxi reigned for 61 years and was the longest reigning emperor. During this period, he made a lot of contributions to the prosperity and stability of the country. He wisely eliminated Obei, pacified the San Francisco, personally conquered Galdan, recovered Taiwan, and sent Nerchinsk troops to defend the country.
In fact, the author can only truly call the emperor Qin Shihuang in history.
The Qin Dynasty was the first unified dynasty in Chinese history. Qin Shihuang achieved the unification of centralized power in various systems and completed the ideological unification of the centralized system . It had a profound impact on Chinese and world history. It pushed China into the era of great unification and established the basic pattern of China's political system for more than two thousand years. The subsequent emperors all followed the example of Emperor Qin's Three Guidelines and Five Constant Rules to manage the people. Therefore, speaking from experience, it is more appropriate for Emperor Qin to be called "one emperor through the ages."
