Has the unified characteristics of tool and humanity. The "Chinese" is also a main subject set by education institutions such as schools in China, and the Chinese textbook generally teaches Chinese universal language characters (i.e. Chinese language). The Chinese phonetic is a scheme of latinization of Chinese phonetic notation issued by the official of the people's republic of China, which means that the letters and spelling methods specified in the scheme of Chinese phonetic alphabet are used to spell a standard pronunciation of modern Chinese, namely the phonetic syllable of Mandarin Chinese. In the course of the character reformation from 1955 to 1957, the Chinese character reformation board was researched and made by the Chinese phonetic alphabet scheme committee of the original Chinese character reformation committee (the current national language and character work committee).
