The Five Hu and Sixteen Kingdoms, the Wei, Jin, Southern and Northern Dynasties, this is a history that has been ignored intentionally or unintentionally. If it is made into a film and television drama, you can only see the bottomless extravagance and lewdness between the high families of the scholars, the cannibalism between father and son, and the ...... of ethnic warfare, full of negative energy; Not only that, the frequent replacement of the imperial throne and the rapid change of the king's flag at the head of the city make the main narrative line chaotic and difficult to grasp. However, we should see that many ethnic groups that depend on each other and live in the land of China with great difficulty have finally completed the great integration in the bloody wind of more than 300 years. This is a positive energy that we should face squarely and deserve to write about. The author of this article is a senior judge and an expert in the second trial business of Shandong Province, who has published a number of law books, and now interprets this magnificent history of more than 300 years from a unique perspective.
