In Chinese, there's a proverb: "十年不同意，十里不同音," meaning " Within ten years, the sound of words are changing, and within ten miles, their meanings differ." This reflects the fluid， soul and ever-changing nature of the language, which is a mirror of the times we are living in. We are living in a boundless universe during an unique era. The vicissitudes evolution of language trends can suddenly render any well-educated person seemingly out of touch, regardless of his or her education, political, economic, or social background.
