After the Rebellion of the Eight Kings of the Western Jin Dynasty, the Central Plains was in chaos. The Han people and the Xiongnu Xianbei Jie Di Qiang accelerated their integration. History is rolling forward. Li Xiong of the Di tribe established the Han Dynasty, Liu Yuan of the Xiongnu established the Han and Zhao regime, and Xianbei Mu Rong Huang established the power of the Yan State, and Sima Rui crossed the river to establish the Eastern Jin Dynasty. Many heroes emerged among them. Zu Ti heard the chicken dance, struck the river, and vowed to regain the Central Plains, composing a tragic and tragic story. Shi Le of the Jie tribe was illiterate and was sold as a slave in troubled times. After many ups and downs, the Hou Zhao regime was established. The Eastern Jin Dynasty was peaceful in a corner, with Wang Xie in power, and internal strife continued. The north was first unified under the Later Zhao Dynasty, then torn apart, and then unified under the former Qin Fu Jian. The Prime Minister of the former Qin Dynasty, Wang Meng, was both civil and military, and assisted the former Qin in dominating the Central Plains. However, Fu Jian wanted to achieve great success. In the Battle of Fei River, he was defeated and fell into the sand. The former Qin fell apart and the north fell into trouble again. Tuoba Gui of the Xianbei clan rose in the desert and established the Northern Wei Dynasty, gradually unifying the north and establishing a stalemate between the north and south of the Eastern Jin Dynasty. One of the heroes of this generation, Liu Yu, was born. He first destroyed Lu Xun and then conquered Huan Xuan. He gradually ascended to the position of a powerful official in the Eastern Jin Dynasty. In his later years, he changed dynasties and established the Liu Song regime. The period of the Southern and Northern Dynasties came. Many stories about the changes during this period are all in "Bitter Jin Gan Zhi". The first part mainly revolves around the dictatorship of Jia Nanfeng, the Rebellion of the Eight Kings, and the founding of the Huns. The dual portrayal of history and heroes is the characteristic of this book.
