Actually, 5,000 years would be more like it. Not 8,000.
Chinese is a real language, but it is one of the most general, non-specific languages yet on earth.
Unlike English, to which new words can be continually added, Chinese words themselves (the characters or pictographs) cannot be increased in number. Therefore, for modern technology and science, the characters must be used in new combinations to describe modern things. Chinese people learning modern technology and science must continually refer to the English language for help, and that they do. It can be said that, in China, where English study is readily available, the country advances. Where English language skills are at their lowest, China virtually remains in the 18th and 19th centuries.
