Since Qin Shihuang swept away Liuhe in 221 BC and led China into feudal society, it was not until the demise of the Qing Dynasty in 1912, and the entire feudal society lasted for nearly two thousand years. In this long feudal society, there is a very interesting historical phenomenon, which is that history is always repeated and cycled. What is the method of repetition? It is the pioneering and enterprising short-lived dynasty - the brilliant and prosperous dynasty - the weak and scattered incompetent dynasty. They have experienced the Qin, Han and Jin dynasties, Sui and Tang Song dynasties, Yuan, Ming and Qing dynasties, I wonder if you have discovered such a rule?

First talk about Qin, Han and Jin dynasties. Qin Dynasty , only a short 15 years, from 221 BC to 207 BC. Although the dynasty was short, it created many firsts, including unified text, weights and measures, and the creation of county system , etc. Then we enter the magnificent Han Dynasty . From 202 BC to 220 AD. During this period, the territory of the country was laid and the Han people were defined. The slogan of those who violated me and strong Han would be punished even if they were far away. Then there is the weak Jin Dynasty , which is completely in chaos, followed by Five Barbarians and Invasion of China , Wei, Jin, Southern and Northern Dynasties , etc. It lasted from 265 AD to 581 AD. During this period, the Han people in the north were unable to withstand the war and were massacred and began to cross the south.

Then talk about the Sui, Tang and Song dynasties. From 581 AD to 618 AD, the second generation of the Sui Dynasty was destroyed. Although the dynasty was short, it was also extremely brilliant. The implementation of the imperial examination system, the creation of the three provinces and six ministries system, and the opening of the Beijing-Hangzhou Grand Canal has really affected thousands of years later. Then there is the peak period of Chinese feudal society . Tang Dynasty , from 618 AD to 907 AD. I don’t need to describe the Tang Dynasty too much, it is completely comparable to the current United States. Chinese people overseas are called Tang people. Then there is the extremely chaotic Five Dynasties and Ten Kingdoms and the weak and incompetent Song Dynasty . Although the Song Dynasty had good economic, technological and cultural development, it was impossible to see the military, and its tragic situation could not be described. Just look at the tragic situation of Song Huizong after being captured and the entire royal family was abused. This period lasted from 907 AD to 1279 AD.

Finally, it is about Yuan, Ming and Qing dynasties. From 1271 to 1368 AD, the duration of Yuan Dynasty was so short, but it also had many great achievements. It was administratively connected to the Eurasian continent and realized that it was going to expedition to Japan for the first time. This was a vision that no dynasty could see. Tibet also entered the territory and established a provincial system, which produced another cultural peak. After the fall of the Yuan Dynasty, it was the magnificent Ming Dynasty. From 1368 AD to 1644 AD, Zheng He voyaged to the West seven times and promoted China's strength. The foreign combat effectiveness was extremely strong, defeating Spain, , Netherlands, , Portugal, and Japan. Taiwan has also been included in the territory. The most surprising thing is that the emergence of capitalism , and the cabinet system that influenced Europe. Then there was the Qing Dynasty, from 1636 AD to 1912 AD. I don’t need to say much about the Qing Dynasty. Everyone knows that they are closed to the country, ceding territory, enslaving the people, and promoting literary inquisitions. They lose to the foreign war power. The Eight-Nation Alliance also invaded China. This is something that no other country has ever seen. More importantly, Japan’s crimes that can never be offset. In short, it has reached the point of destruction of the country and the race.

or above is the unique feature of Chinese history, that is, history always repeats and cycles. This also confirms from the indirection that our nation is forgetful and unlearning lessons. Alas, a long sigh and helplessness...
