The "History of the Five Emperors Benji" records: "The Mingde of the world began with Emperor Yu. "The Yu Dynasty is a dynasty that is more ancient than the Xia Dynasty recorded in the history books, "Yu Shun" is also the Shun Emperor Yao Chonghua, the name "Chonghua" is related to Shun's "Double Pupil Ren (Heavy Pupil)", that is, the appearance of a saint or emperor, and the ancients also called the people by Shun's name "Hua".
After the establishment of the Xia Shang Zhou, the ceremonial system was complete, and there were "Hua", "Xia" and "Huaxia", "Hua" also referred to "Hanfu", which was different from the Siyi (Sifang) costume, and Xia refers to the big country that performed Zhou rituals, so it has the reputation of a state of etiquette and a country with a crown.
During the Spring and Autumn Period and the Warring States Period, Confucianism attached importance to filial piety, and Yu Shun was known for filial piety, so the "Shun" culture had a far-reaching influence, and at that time, the princely states of Qi, Chu, Qin, Yan, Zhao, Wei, and Han were also known as "Zhuxia", which was a powerful Chinese princely state at that time.
In 221 BC, Qin Shi Huang ended the division of the Spring and Autumn Warring States for hundreds of years, and completed the great unification for the first time, he believed that his merits were higher than the "Three Emperors and Five Emperors", so he was called "Emperor", "朕" also became the exclusive title of the emperor, and then unified the writing, currency, weights and measures.
After Qin Shi Huang unified the Central Plains, he also gave China a noble and domineering name, which has been used to this day, this name is "Zhonghua", which is recorded in the "Liezi Yellow Emperor" and "Chinese Jin Language", Hua Xu is the ancestor of Yanhuang, and the world is called "Yanhuang Descendants".
At that time, Qin Shi Huang swept through the Six Kingdoms, full of spirit, believing that his Central Plains region was still in the middle of the world, so he took "Zhong", and his merits were above the "Three Emperors and Five Emperors", which traced back to the ancestor of Yanhuang and took "Hua", that is, "Zhonghua".
During the reign of Qin Shi Huang, the construction of the Great Wall, the repair of the Chi Road, the construction of the Golden Causeway, the repair of the mausoleum, etc., the scale of each project is very huge, causing a lot of pressure on the common people, it can be said that the amazing ancient buildings seen today are still based on the sacrifices of the ancients.
The word "Zhonghua" was not widely spread during the Qin Dynasty, until the end of the Qin Dynasty, the establishment of the Han Dynasty, the deposing of hundreds of families, the exclusive respect for Confucianism, the rapid development of Han culture, like "Han People", "Han Nationality", etc., during the Han Wudi period, defeated the Xiongnu, making the Xiongnu go north, known as the "Whip of God" by Europeans.
It also opened up the Silk Road and established the connection between the Han Dynasty and all countries in the world; during the reign of Liu Xiu, the Emperor of Han Guangwu, Confucianism was vigorously promoted, and the festival was promoted, creating the era of "Guangwu Zhongxing", which was the most weathered and the most prosperous in history.
Liu Xiu can be described as a very peculiar emperor in history, after he unified the world again, the people were just liberated from suffering, in order to restore and develop the Central Plains as soon as possible, Liu Xiu did not take the initiative to launch wars, diligent in government affairs, concentrated on governing the country, in order to reduce the poor people selling themselves as slaves, often distributed relief grain, reduced rent and servitude, and dismissed corrupt officials, and the land of China was once again full of vitality.
In addition, Liu Xiu was one of the few emperors in history who treated meritorious people well, and gave the meritorious people the title of Tian Zhao, a high-ranking official Houlu, but only relieved the meritorious men of their military powers, and left a testament before his death: "I am not beneficial to the people, and everything in the future is in accordance with the Xiaowen Emperor system, and we must be thrifty." In short, Liu Xiu is a rare "zero bad evaluation" emperor in history.
The explanation given by the largest comprehensive dictionary in our country is: "The middle one, also dwelling in the four directions; the Chinese, the cultured nation, the beautiful clothing also." After that, the territory became more and more extensive, and everything to which it belonged was called China, also known as China. Today's China is based on Chinese civilization and Chinese culture, common Chinese, Chinese characters, Han and ethnic minorities collectively known as the "Chinese nation.".
