Chinese civilization is also known as the "Huaxia Civilization". "Huaxia" were the predecessors of Chinese Han people. Chinese Civilization can be traced back to the 26th century B.C. when the Yellow Emperor, the founding father of the Chinese nation, unified the Central Plains. Since then, Chinese civilization has existed for over 5000 years. In terms of language, written characters, philosophy, literature, calligraphy, painting, drama, architecture, gardens and cuisine, the five thousand year history of Chinese civilization is clearly visible. As one of the world's four major ancient civilizations, Chinese Civilization is well known for its continuity and the fact it was never wiped out by war, changes of dynasties, or simply by people forgetting their culture.
