Hanyu Pinyin: The Latinization plan for Chinese character phonetic notation officially promulgated by the People's Republic of China. It was adopted by the former Chinese Character Reform Commission (now the National Language and Character Working Committee) during the character reform from 1955 to 1957. The Chinese Pinyin Plan Committee researched and formulated it. This pinyin scheme is mainly used to annotate the pronunciation of Mandarin Chinese as a Mandarin phonetic symbol of Chinese characters.

The National People's Congress approved and announced the plan on February 11, 1958. In 1982, it became the international standard ISO7098 (Chinese Roman alphabet spelling). Some overseas Chinese areas such as Singapore use Hanyu Pinyin in Chinese teaching.

In September 2008, Taiwan, China determined that the Chinese transliteration policy would be changed from "Tongyong Pinyin" to "Hanyu Pinyin". All parts involving Chinese transliteration will be required to use Hanyu Pinyin, which will be implemented starting in 2009. .
