If compared to a river, the Chinese culture is a river that never goes dried, although its water is sometimes abundant, sometimes not. The reason for that is the instillation of new water that was quite frequent in history.And there are two major origions for it, one is in India,the other is in the West. Basically, it was driven by translation. which is the Elixir of life for our culture to be ever green. How useful translation is!
