Syllable breaking means that the spike syllable is the smallest phonetic unit of the monophonic phoneme and consonant phoneme in the phonological family, and the monophonic phoneme can also form its own syllable. There is no concept of syllable in Chinese, and syllable is a loan word; Chinese syllables consist of vowel phonemes and consonant phonemes in the phonetic family.

Hanyu Pinyin is a Latin Pinyin scheme for Chinese characters promulgated by People's Republic of China (PRC), which refers to the phonetic syllables of standard pronunciation of Mandarin in modern Chinese, and consists of letters and spellings specified in the Hanyu Pinyin scheme. 1955-1957 was studied and formulated by the Chinese Pinyin Scheme Committee of the former China Language Reform Commission (now the State Language Commission).
