After the Han and Jin Dynasties, foreigners gradually came to China and lived in the interior. Subsequently, the Five Hus and Sixteen Kingdoms rose and fell one after another. Later, the weak preyed on the strong, swallowed each other up, moved around, and combined the sixteen kingdoms into one big country, called the Northern Wei Dynasty. Later, internal strife broke out again in the Northern Wei Dynasty. The east was divided and the west was divided, and there was no time to take care of Jiangnan, so Jiangnan was still preserved. When the Eastern Wei Dynasty was changed to the Northern Qi Dynasty and the Western Wei Dynasty was changed to the Northern Zhou Dynasty, the Western Territory was divided into three parts. The Zhou Dynasty was the strongest, the Qi Dynasty was the second, and the Jiangnan region was the weakest. The tripartite war lasted for several years. Qi was merged with the Zhou Dynasty, but only two-tenths of Jiangnan remained, almost all belonging to the Northern Zhou Dynasty. A great prime minister, Yang Jian, was chosen. He usurped the Zhou Dynasty and re-annexed the south of the Yangtze River. He accepted Zhou Chan and destroyed the Chen family, and actually unified the Central Plains and merged the north and the south. Li Yanshou of the Tang Dynasty wrote a history of the north and the south. The Song, Qi, Liang, and Chen belong to the south, while the Wei, Qi, Zhou, and Sui belong to the north. The meaning is very strict. Not only is the Yang family's business, it is a cicada of the Northern Zhou Dynasty, it can belong to the history of the north. Even the friendship between the Yang family and his son does not look like a real person who governs the world. The boy performed the story according to the example, imitated the genre of the story, and compiled a "Romance of Northern and Southern History".
