Mandarin Chinese
Mandarin is defined and designed based on Beijing accent. In China, there are over 600,000 dialects and more accents although they all use Chinese language and characters, but their pronunciation and some expressions are totally different. China must find a standard pronunciation to allow all people to understand each other and communicate. Beijing has been the capital city of China for more than 1,000 years, so China defined Beijing Accent as standard Mandarin.
