The Qin Dynasty and the Tang Dynasty were greater than the Han Dynasty. Why are we called Han people and not Qin and Tang people?

After the unification of Qin, the clan name of Huaxia was still used. However, the people who originally belonged to the six countries in Shandong (east of Mount Wei) have become the "heads of Guizhou" in the Qin Dynasty. Although the Qin Dynasty was short-lived, the ethnic groups in the Western Regions (including present-day Xinjiang) and the Xiongnu still called the Central Plains people Qin people until the Han Dynasty. The Han Dynasty lasted for more than 400 years from the Western Han Dynasty to the Eastern Han Dynasty, which provided the historical conditions for the name of the Han Dynasty and the name of the Chinese nation. In addition, the Han Dynasty was so powerful that in foreign exchanges, other ethnic groups called the Han Dynasty’s armies “Han soldiers,” the Han Dynasty’s envoys “Han envoys,” and the Han Dynasty’s people “Han people.” Therefore, when the Han Dynasty conquered the Western Regions, conquered the Xiongnu, pacified the Western Qiang, conquered Korea, conquered the southwestern barbarians, conquered Fujian, Guangdong and Southern Guangdong, and had unprecedentedly frequent exchanges with surrounding ethnic minorities, the name of the Han Dynasty was called by other ethnic groups. It is the name of the Chinese nation. Lu Simian said: "The name of the Han people started after Liu Bang became emperor." Lu Zhenyu said: "The Chinese people started to be called the Han people after Emperor Wu of the Han Dynasty declared the emperor." In short, the name of the Han people started from the Han Dynasty.

From then on, no matter how the descendants of the Chinese in the Central Plains changed dynasties, people called their people Han people. This is the origin of the Han nation.

It has continued since then. During the Han dynasty, the northern territory of the Han Dynasty was conquered by the Xiongnu, and the northern territory of Langjuxu was pushed to the Hetao, north of the Yinshan Mountains; the northwest was unified with all the countries in the Western Regions, and the Western Regions Protectorate was established; the southern part was conquered by Nanyue, and Hainan Island was also occupied; the southwest was conquered by the Han Dynasty The borders were moved to the Ailao Mountains in Yunnan and the Li Mountains in Gaogong; the Northeast region was destroyed by the Weiman Dynasty and North Korea was established, and the four northeastern counties were established. The system of three officials and nine ministers was implemented; the local administration was changed from the original two-level system of counties and counties to the three-level system of prefectures, counties and counties; the population increased significantly; the military system was strictly regulated; the country focused on the construction of water conservancy and agricultural development; the right to operate salt and iron was recovered The central government expanded financial resources; deposed hundreds of schools of thought, only respected Confucianism, classified Confucian culture as a unified feudal orthodox culture, and opened up the famous "Silk Road"; many commercial centers emerged across the country; in terms of history, Sima Qian's "Historical Records", Ban Gu "Book of Han"; ancient classics developed; Yuefu was established to collect folk poetry; Han Fu became popular; official script gradually replaced Xiaozhuan as the main writing font; in terms of science and technology, Cai Lun improved papermaking, and Zhang Zhongjing's "Treatise on Febrile and Miscellaneous Diseases" , Hua Tuo was the first doctor in the world to use general anesthesia, invented porcelain firing, began to use the compass, Zhang Heng's seismometer, and the "Taichu Calendar" formulated by Luo Xiahong and others, and Taoism was formed. China, with its passionate Han attire, is called the Han Dynasty.

The Han Dynasty, the Tang Dynasty, and the Song Dynasty played a very important role in the development of ancient Chinese society and the formation of the Chinese nation in the history of China's feudal society for more than 2,000 years. In the long river, national unity, cultural prosperity, strong martial arts, and far-reaching national prestige are the common characteristics of the Han, Tang, and Song dynasties. The Han Dynasty had the rule of Wenjing, the Hanwu Dynasty, etc., while the Tang Dynasty had the rule of Zhenguan and Kaiyuan. The Song Dynasty was a highly prosperous era of economy, culture, education, and scientific innovation in ancient Chinese history. In the third year of Xianping in the Northern Song Dynasty (1000), China's total GDP was US$26.55 billion, accounting for 22.7% of the world's total economy, and its per capita GDP was US$2,280, and the per capita GDP of West Asia was US$621; both exceeded the per capita GDP of Western Europe at that time, which was US$427.

However, the Chinese consciousness of a world under heaven was formed in the Han Dynasty, and the connotation of a world under heaven was supported by culture. It is economic exchange, plus another pillar is cultural unification. This is an important reason why the Han Dynasty is the Han Dynasty instead of the Tang and Song Dynasties.
