hy are their different languages in chinese
Standard Chinese (known in China as Putonghua), a form of Mandarin Chinese, is the official national spoken language for the mainland and serves as a lingua franca within the Mandarin-speaking regions (and, to a lesser extent, across the other regions of mainland China).anguage laws of China do not apply to either Hong Kong or Macau and hence have different official languages (Cantonese, English and Portuguese) than the mainland. For example, Tibetan has official status within the Tibet Autonomous Region and Mongolian has official status within Inner Mongolia.
