It is rich and colorful languages that shape and reflect human literature, culture, religion, education, and even economy. The crucial roles that languages play in forging human behaviors and psychological activities, or the ways we think and work, can never be overemphasized, but these roles are still beyond human power of cognition. Languages are the rivers of the usages, or the sediments accumulated within eons in the ocean of history. The river flow or flood at sometime over the plateau of human thinking and eventually etch out the plateau a profound canyon, which, ironically, in turn, captivates and imprison the human thoughts.

Unfortunately for some unknown reasons, languages, like some fragile species that have experienced the ups and downs in the long evolution, also have their own life span. Some vanishes, as did the Nineveh. Some ekes out its vicissitudes. Following the course of nature, languages come and go. But why do they evolve as they did rather than in a different way? Why do they change and vary? Why it is some of them rather than others that die out? Millions myths haunt and daunt those who trouble themselves in delving the answers. Countless accounts, theories, hypotheses emerged and submerged just as did the languages. Unfortunately even today these questions remains to be answered. (113)
To sum up, I am fully convinced that language, as a symbol of a national character, should be carefully preserved as long as possible, so that the descendent would have a opportunity touch and feel the history and tradition with their own hands and eyes.
