The Chinese culture can be termed as unique and exclusive in its own rights. This can be attributed to the fact that the Chinese civilization fostered in a huge area. For easier comprehension, its geographical spread was a third larger in size than that of United States, if Manchuria, Mongolia and Tibet are included. For many centuries China led a secluded life and did not have an influence from other civilizations as it was separated by geographical bodies like mountains, deserts and seas which were difficult to cross at that time.
Mainland China is divided by the three significant river systems which originate from a common source on the elevated Tibetan Plateau and go eastward to empty in the Pacific Ocean. Along with the three river systems three mountain ranges also begin in the westward of China and retreating towards the east. The most famous river is the Yellow river, it is also infamously named the yellow sorrow because of the major devastation it brought time and again by the floods it caused in the northern China plain. The climatic conditions here are quite alike to that of Western Europe. The other main river is the Yangtz River and its alongside valley. On the southern periphery of this valley is the subtropical land of China. These subtropical regions are the inception lands of the various cultures of China that were many times destroyed and modified by Chinese expansion. The shorter rivers and valleys meet at the canton to be called as the third major river system of China.
In the entire history of China, these mountain ranges and river systems have acted as major hindrances in developing political unity in China. Ironically the river valleys acted as the facilitators for spreading similar cultural values throughout China, much more than in any other zone of the world. So in spite of the political disparity, China has witnessed cultural unity in its colorful history.
