China is a multi-ethnic country with Chinese civilization as its source, Chinese culture as its foundation and Han nationality as its main body. Commonly used Chinese and Chinese characters. The Han nationality and ethnic minorities are collectively referred to as the "Chinese nation", and they also call themselves descendants of the Chinese people and dragons.

China is one of the four ancient civilizations in the world with a long history. About 5000 years ago, settlement organizations centered on the Central Plains began to appear, and thus a country was formed. After many ethnic exchanges and dynasty changes, the unified situation of multi-ethnic countries was finally formed.

After the Revolution of 1911 in the early 20th century, the imperial system withdrew from the historical stage, and the * * * and political power were established. 1949 after the founding of People's Republic of China (PRC), the people's congress system was established in Chinese mainland.

Extended data:

First, the terrain

China is high in the west and low in the east. Mountains, plateaus and hills account for 67% of the land area, while basins and plains account for 33% of the land area. The mountains are mostly east-west and northeast-southwest, mainly including Altai Mountain, Tianshan Mountain, Kunlun Mountain, Karakorum Mountain, Himalayan Mountain, Yinshan Mountain, Qinling Mountain, Nanling Mountain, Daxinganling Mountain, Changbai Mountain, Taihang Mountain, Wuyishan Mountain, Taiwan Province Mountain and Hengduan Mountain.

There is the highest Qinghai-Tibet Plateau in the world in the west, with an average elevation of more than 4,000 meters. It is called "the roof of the world", and Mount Everest is the highest peak in the world, with an altitude of 8844.43 meters. Inner Mongolia, Xinjiang, Loess Plateau, Sichuan Basin and Yunnan-Guizhou Plateau in the north and east are the second steps of China's topography.

Daxinganling-Taihang Mountain-Wushan Mountain-Wuling Mountain-Xuefeng Mountain is the third step, and the coastline from east to east is mostly plain and hilly. The continental shelf to the east and south of the coastline is rich in seabed resources.

Second, the terrain features

The terrain is changeable. On the vast land of China, there are majestic plateaus, rolling mountains, vast plains, low hills and large and small basins surrounded by mountains and low in the middle. There are five basic land types in China, which provide various conditions for the development of industry and agriculture in China.

The mountains are vast. Usually people call mountains, hills and rugged plateaus mountains. China's mountainous area accounts for 2/3 of the country's total area, which is another remarkable feature of China's topography. The vast mountainous areas bring certain difficulties to the development of transportation and agriculture. Mountain areas can provide forest products, minerals, hydropower and tourism resources, which provides resource guarantee for changing the face of mountain areas and developing mountain economy.

Topography is the general trend of surface fluctuation.
