Formerly known as rhyme Vowels consist of three parts: the beginning (middle tone), the belly (main vowel) and the end. According to vowel structure, it can be divided into single vowel, compound vowel and nasal vowel.

Now acronym:

1. According to the provisions of the Chinese Pinyin Scheme, Y and W are zero initial syllables with vowels, and I and U are rewritten. For example, the syllable yan is a rewriting of the zero initial syllable ian, that is, yan as a whole, so Y and W are not initials; But according to people's customary spelling, Yan will spell with initials, that is, y-an-yan, so both Y and W are counted as initials.

2. The ending ng belongs to nasal consonants, but it is no longer used as an initial in the pronunciation system of Putonghua, so it is not in the category of initial in Putonghua, but it may appear in the form of initial in some dialects.
