The word "China" appeared very early in our country's classical literature and is also commonly used. This term first appeared in the early Western Zhou Dynasty about 3000 years ago. On a cultural relic from the period of King Wu of the Western Zhou Dynasty unearthed in 1963, there is an inscription with the words "Yu Qizhaizhong or". According to research by archaeological and philological experts, "Zhongor" is "China". The meaning of the Chinese character Guo in ancient my country is interpreted as "domain" or "bang". "China" means the "Central Realm" or the "Central Gang". In ancient anthologies, the word "China" has five different meanings: One is specifically referring to the capital where the emperor is located, that is, the capital. For example, "The Book of Songs, Daya, and Minlao" "Benefit this China to ease the four directions" (first care for the people in Kyoto, and then appease the four directions); "Mencius, Gongsun Chou": I want China and grant Mencius a house..." (I want to Build a house for Mencius in the capital and let it educate the disciples of the emperor); the second refers to the kingdom directly ruled by the emperor; the third refers to the Central Plains area; the fourth refers to the interior of the country; the fifth refers to the area where the ancient Chinese and Han people lived or the country established. The Huaxia and Han nationalities mostly established their capitals in the north and south of the Yellow River, and continued to expand their activities. Therefore, the middle and lower reaches of the Yellow River were called "China", which has the same meaning as "Zhongtu", "Zhonghua", "Zhongzhou" and "Zhongyuan". After the Qin Dynasty, The meaning of the word "China" has changed. During the Han Dynasty, people often called the Central Plains dynasty established by the Han people "China", and the Central Plains dynasties established by the fraternal ethnic groups were also called "China". During the Southern and Northern Dynasties, the Southern Dynasties called themselves "China". , but the Southern Dynasties were called "Island Barbarians". The Liao Dynasty and the Northern Song Dynasty, and the Jin Dynasty and the Southern Song Dynasty all called themselves "China" and did not recognize the other as "China". Strictly speaking, "China" in ancient times was an adjective, not a proper term. Noun. This means that none of the dynasties in ancient my country used "China" as the official country name. For example, the country name of the Han Dynasty was Han, the country name of the Tang Dynasty was Tang, and the country names of the later dynasties were Song, Liao, Jin, and so on. During the Yuan and Ming dynasties, the name of the country signed in the treaties signed by the Qing government and foreign countries was "Qing". Therefore, the word "China" appearing in historical records is not the same as what we refer to today. It was not until after the Revolution of 1911. After the liberation of the country, we also used "China" as the abbreviation of "The People's Republic of China". Now there is only one China in the world, which is the People's Republic of China. .2
