Brief introduction of Han dynasty:
The Han Dynasty (206-220 BC) was a unified dynasty after the Qin Dynasty, which was divided into two periods: the Western Han Dynasty and the Eastern Han Dynasty. Among them, the Western Han Dynasty experienced thirteen emperors, which lasted 2 14 years. Fourteen emperors spread in the Eastern Han Dynasty, which lasted 195 years.
At the end of the Qin Dynasty, when the peasants revolted, Liu Bang and Xiang Yu overthrew the Qin Dynasty and were named Hanwang. Later, Liu Bang defeated Xiang Yu in the Chu-Han dispute, proclaimed himself emperor in the first 202 years, established the Han Dynasty, and made Chang 'an its capital, which was called the Western Han Dynasty in history. At the beginning of the Han Dynasty, the rulers used the technique of Huang Lao to recuperate, and the rule of Wenjing appeared.

In the late Western Han Dynasty, consorts were in charge of politics, and there were many social contradictions. In 8 years, Wang Mang, a consort, abolished the obedient son of the Han Dynasty, established a new Mang, and the Western Han Dynasty perished. At the end of Xin Mang, the Red Eyebrow Uprising in Greenwood broke out, and Liu Xiu, the imperial clan of the Han Dynasty, rebuilt the Han Dynasty, making Luoyang its capital, which was called the Eastern Han Dynasty in history. After Liu Xiu unified the world, he stopped the war and supported the people, and martial arts recovered. Zhang Ming's second emperor ignored Bo Fu and began Zhang Ming's rule.
After the Han and Emperor succeeded to the throne, they attacked the Xiongnu, sent Ban Chao to govern the western regions, and expanded the Silk Road, which made the national strength of the Eastern Han Dynasty extremely strong. At the end of the Eastern Han Dynasty, there were many disputes between officials and officials, and there were two disasters of parties. After the outbreak of the Yellow Scarf Uprising, the Han Dynasty went into decline. In 220, Cao Pi usurped the Han Dynasty and the Han Dynasty perished.
