Of course, in a broad sense, the 800-year-old Zhou Dynasty and the 400-year-old Han Dynasty are also among them, but both dynasties have reasons for not being selected.
Although the Zhou Dynasty enjoyed the country for 790 years, it was not a centralized dynasty after all, and its enfeoffment system was strictly one completely independent small country after another, which could not be called a unified dynasty. In academic conclusion, the late Qin Dynasty was the first truly unified centralized dynasty.
Let's talk about the Han dynasty first. Although the Han Dynasty was 405 years old, there was a new dynasty Wang Mang usurping the Han Dynasty, which really broke 15 years, and it was not completely coherent. Therefore, as far as the dynasties that have survived are concerned, the Han Dynasty cannot be included.
As for other dynasties that we are familiar with: 289 years in the Tang Dynasty, 276 years in the Ming Dynasty and 268 years in the Qing Dynasty, none of them lasted more than 300 years. The only one over 300 years old, as we just said, is the Song Dynasty-319.
It is estimated that many people are beginning to wonder why only the Song Dynasty did this in history.
Maybe you think I will analyze it from the times, economy and military, but my answer is actually only one-luck.
Yes, the Song Dynasty was lucky. It's that simple. /kloc-After the establishment of the Song Dynasty in 0/67, it was devastated, but fortunately, it survived without any fault in the middle.
This year, the Northern Song Dynasty was overthrown by the State of Jin. Fortunately, Zhao Gou, the King of Kang, went to the south and continued the bloodline of the Song Dynasty. At the same time, during this period, the later "Four Generals of Zhongxing" Yue Fei and Han Shizhong appeared in the Southern Song Dynasty. In this way, the Song Dynasty continued the history of 152 years.
Many people divide the Song Dynasty into the Northern Song Dynasty and the Southern Song Dynasty. In fact, they are more divided from territory. As far as royal blood is concerned, the Song Dynasty has never been broken from beginning to end.
Kang Wang was the ninth son of the last emperor of the Northern Song Dynasty.
Of course, we don't envy how powerful the Song Dynasty was. After all, the combined history of the Northern Song Dynasty and the Southern Song Dynasty is only 3 19 years. It has just passed the 300-year period and survived for 19 years.
Having said that, we can't help thinking of another question. Why did these ancient unified dynasties, even the Tang, Song, Ming and Qing dynasties in the heyday of the world, have a life span of more than 200 years and less than 300 years?
The ancients often said: many people will exhaust. Does this so-called luck really exist?
Judging from the age of human beings, even if medical technology is so developed now, we humans are generally seventy or eighty years old, which is irreversible. Even if some people can live to be over 100 years old, it is really rare.
