The whole world knows the four ancient civilizations, the Chinese civilization, the ancient Babylonian civilization, the ancient Egyptian civilization, the ancient Indian civilization, and the only surviving chinese civilization at present has continued.
However, there is a Wuhu era in history, the war lasted for 300 years, the Hu people brutally ruled over the Han people, slaughtered and plundered, and the farmland was abandoned, from about 20 million in the Three Kingdoms period, to about 4 million, at that time, not to mention that the Chinese civilization was forever passed down, and almost the Han people were extinct.
Today, let's talk about this Wuhu era, wuhu refers to the five ethnic minorities of xiongnu, xianbei, karma, krypton, and qiang (for the sake of good memory, it is widely spread that the Xiongnu Xianbei grabbed the land. Wuhu Chaohua refers to the period when many nomadic people outside the Western Jin Dynasty took advantage of the rebellion of the Eight Kings of the Western Jin Dynasty and the weakening of their national strength to establish several non-Han regimes and form a confrontation with the Southern Han regime.

The Sixteen Kingdoms period represents the period between the fall of the Western Jin Dynasty and the unification of Northern China by the Northern Wei Dynasty, when the South was the Eastern Jin Dynasty, in addition to the Sixteen Kingdoms, there were other races and Han people in the North established by other regimes such as Ran Wei, Western Yan, and Dai, totaling more than twenty, from which the Sixteen Kingdoms with a longer time, great influence, and more representative sixteen kingdoms were selected, and it is said that the "Sixteen Kingdoms" is derived from the "Spring and Autumn of the Sixteen Kingdoms" privately written by the historian Cui Hong at the end of the Northern Wei Dynasty. Therefore, later historians called the period from 304 to 439 the Five Hu and Sixteen Kingdoms.
Many people are not clear about the Sixteen Kingdoms in China's history, and some do not know at all that there is a period of the Sixteen Kingdoms in Chinese history, so in order to facilitate memory, we will roughly sort it out today.
We all know the order of the Eastern Jin Dynasty, Song Qi, Liang Chen; these sixteen countries, the simple map can be seen at once a little can not remember, then we come to find a convenient slip of the tongue: five liang, four yan, three Qin, two Zhao, one Han and one summer.
Five cool: front cool, south cool, north cool, west cool, back cool
Four swallows: former yan, southern yan, later yan, northern yan
Three Qins: Former Qin, Later Qin, Western Qin
Erzhao: Former Zhao, Later Zhao
Yi Han: Cheng Han
Yixia: Hu Xia
These sixteen kingdoms did not exist at the same time, not like the Three Kingdoms period, the Cao Wei regime, the Eastern Wu regime, and the Shu Han regime, but there was a successive demise, a magnificent process of expansion and robbery.

During the Period of the Five Hu and Sixteen Kingdoms, there were frequent changes in political power, there were constant struggles, the countries established by the Five Hus were governed by Hu and Han, and their crossed ruling areas can be known that this is a typical history of ethnic minorities entering the Central Plains, and the policies of ethnic inward migration and emigration during the Han Liu Bang period reached unprecedented chaos and urgency during this period, and the period when ethnic minorities seized the right to rule through military force can be called the darkest era, and the tragic situation of "white bones exposed in the wild, no chickens chirping in thousands of miles, and one hundred lives and one left behind" reappeared in the land of China, known in history as "Wuhu Chaohua". Although there were constant wars between the Han and ethnic minorities during this period, it was a process of great ethnic integration.
During the Wuhu period, especially former Qin Fu Jian, Northern Wei Tuoba Hong, these two emperors are the most representative emperors of Sinicization, Fu Jian's ideal is the Confucian saint king, so he opened the school widely, summoned Han Confucian scholars to teach, Confucianism prevailed, but unfortunately he ruled most of the region in the Battle of Shuishui, and was gradually disintegrated and defeated. Tuoba Hong ordered the prohibition of Hufu and Xianbei languages, and changed the Xianbei surname to a Han surname, such as Changing Tuoba to a Yuan surname. As a result, many ethnic minorities have gradually sinicized, so that Chinese civilization can be passed on.
The Northern Hu regime of the Five Hu and Sixteen Kingdoms and the Eastern Jin Dynasty regime in the south were finally pacified by Yang Jian, the founding emperor of the Sui Dynasty, established the Sui Dynasty, and completed the unification of the Sixteen Kingdoms, which also responded to the sentence of the "Romance of the Three Kingdoms": "Unity will be divided for a long time, and it will be united for a long time."
