Hi Pinyin is as follows:

huì, àn.

Pinyin, the process of spelling out a syllable, is the process of making a syllable by combining the consonants, mediators, and rhymes in rapid succession and adding tones according to the rules of syllabic composition in Mandarin.

Hanyu Pinyin is the Chinese character Latinization scheme of the People's Republic of China*** and the State of China, which was studied and formulated by the Committee on Hanyu Pinyin Scheme of the former Chinese Character Reform Commission (now the State Language and Literature Working Committee) during the 1955-1957 character reform.

Uses of Pinyin:

1. For phonetic transcription of Chinese characters: Beginning in the fall of 1958, language textbooks for elementary school nationwide adopted hanyu pinyin for phonetic transcription of Chinese characters, followed by secondary school textbooks, dictionaries, and lexicons, as well as popular readers and literacy textbooks.

2. For teaching Mandarin: After the publication of the Hanyu Pinyin Program, Mandarin textbooks, reading materials, character lists, dictionaries, and dictionaries using Hanyu Pinyin were published one after another, which contributed to the promotion and popularization of Mandarin.

3. It is used in the notation and ordering of dictionaries and thesauruses, and in the indexing of books and magazines. The 75-volume Encyclopaedia of China adopts hanyu pinyin in its ordering, and every entry in the main text is annotated with hanyu pinyin.

4. As a ****same basis for the creation and reform of the script of China's ethnic minorities. China already has Zhuang, Miao, Dong, Hani, Lisu, Wa, Li, Naxi, Tu and other ethnic minorities to adopt Hanyu Pinyin consistent letter form.
