1, peasant uprising at the end of Qin dynasty, Chu-Han dispute. Liu Bang, the emperor gaozu of Han Dynasty, was a man named Pei Fengyi, who did not take part in agricultural labor at ordinary times. In his youth, Qin Shihuang had unified China, and he became the curator of Qin Sishui Pavilion, which was very close to county officials. Liu bang was unruly all his life, but he was brave, ambitious and generous and could live up to expectations. In the first year of Qin Ershi (209 BC), a peasant uprising broke out at the end of Qin Dynasty. Liu Bang also fought in Pei County, his hometown, and was called Pei Gong. Later, he joined Xiang Shu's resistance to Qin Yijun. In the first 207 years, Liu Bang led the troops into the customs, and Zi Ying, the king of Qin, fell and Qin died. After the demise of the Qin Dynasty, in 206 BC, Xiang Yu named Liu Bang Hanwang. Later, Xiang Yu and Liu Bang launched a four-year battle between Chu and Han. With the help of Xiao He, Han Xin, Sean and Peng Yue, Liu Bang defeated Xiang Yu in the Battle of Gaixia. In the first 202 years, he officially proclaimed himself emperor in Dingtao, still taking "Han" as the capital and Chang 'an (now Shaanxi An) as the capital.

2, the rule of Wenjing, the chaos of the seven countries, the country of South Vietnam. After Lv Hou's death, the rebellion of Zhulu was eradicated by the ministers headed by Zhou Bo, and the ministers embraced Emperor Wen in succession. Under the influence of Dou, the Empress of the Han Dynasty, Emperor Wen and his son Jingdi continued to adopt the method of governing by Huang Lao's inaction, and implemented the policy of being frivolous and generous, sharing interests with the people, which restored the great damage caused by years of war and reduced the burden on the people.

Although the only turmoil in this period occurred during the reign of Emperor Jing of Han Dynasty-the "Seven Kingdoms Rebellion", it was pacified by Zhou Yafu and Luan Bu only three months later, and it did not have a substantial impact on the Han Dynasty.

3. Zhao Xuan Zhongxing. In the later years of Emperor Wu of the Han Dynasty, a famous "witch disaster" happened, which resulted in unjust death. The Han dynasty experienced many years of war, which had a great impact on the economy, resulting in the weakness of the national strength of the Han dynasty and the squandering of the savings of the previous dynasty. To this end, Emperor Wu of the Han Dynasty promulgated the famous Imperial Decree of Luntai in his later years, and he was no longer militaristic. In order to save the economy during the period of Emperor Wu of the Han Dynasty, a series of policies were adopted, such as putting money, salt and iron under the central management, strengthening agricultural production, implementing and legalizing it, digging the White Canal, establishing the policy of equal loss and leveling, stabilizing prices and strengthening economic control.

Xin Mang usurped Korea. After the death of Emperor Gaozu of Han Dynasty, Emperor Liu of Han Dynasty ascended the throne, and the Western Han Dynasty began to decline. Emperor Han and Yuan were soft-hearted and Confucian, which led to the decline of imperial power and the rise of consorts eunuchs. After the death of Emperor Yuan of Han Dynasty, Emperor Liu Ao acceded to the throne. Emperor Han Chengdi was a lecherous, and he loved Queen Xu, Ban Jieyu and Zhao's sisters (Zhao and Zhao Hede) successively. Because Zhao's sister couldn't have children, Han Chengdi and other concubines' children were killed by Zhao's sister, which was called "Yan pecked at the emperor's grandson" in history. Because "wine invades the bones", Emperor Hancheng finally died in the gentle country.

5. Guangxu Zhongxing. Xin Mang was destroyed by Red Eyebrows and Greenwood Uprising. The outlaws made Liu Xuan, the imperial clan of the Han Dynasty, emperor, and restored the title of the Han Dynasty, which was called Xuanhan in history, and changed the dynasty, and Liu Xuan became emperor again. In a.d. 25, the Red-Eye Army established Liu as Emperor, which was later called the Han Dynasty and was known as the Red-Eye Han in history. When the Yuan Dynasty was founded, Liu Pengzi established the world emperor, and then defeated the outlaws.
