Introduction to Pinyin:

Hanyu Pinyin (hànyǔpξnyξn) is a Latin Chinese character scheme in People's Republic of China (PRC), which was researched and formulated by the Hanyu Pinyin Scheme Committee of the former China Language Reform Committee (now the State Language Committee) during the language reform from 65438 to 65438 to 0957.

Chinese Pinyin is a tool to assist Chinese pronunciation. Article 18 of the General Language and Characters Law of People's Republic of China (PRC) stipulates: "The Chinese Pinyin Scheme is a unified standard for spelling Roman letters in Chinese names, place names and Chinese documents, and it is used in areas where Chinese characters are inconvenient or unusable." The symbols written according to this set of norms are called Chinese Pinyin.
