In primary school teaching, students are often required to write a capital letter that is the first letter of Chinese Pinyin, which refers to the first letter to look for when arranging a word in a dictionary in alphabetical order. This is the application of phonology, not the meaning of phonology itself.
In addition, there are no Chinese characters with initials I, U and v(ü), so the initials of Chinese pinyin are arranged as follows: aa bb cc DD ee ff gg hh jjkk ll mm nnoop QQ RR SS TT wwxx YY ZZ.
Phonetic order refers to the case of the first letter of a syllable, and syllable refers to the whole pinyin (including initials, finals and phonetic symbols).
Syllables are the most natural phonetic units that can be felt by hearing, and are composed of one or several phonemes according to certain rules. In Putonghua, a Chinese character is a syllable except for a few cases.
Mandarin syllables are composed of initials, finals and tones, and finals can be divided into rhyme head, rhyme belly and rhyme end.
The phonetic symbols are A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, W, X, Y, Z, and a V is missing. Because it can't be sequenced or read. But now it can be used in the word "female" and so on, and it can be typed.
The initials are arranged in the order of 26 letters.
Among them, Chinese Pinyin is sorted alphabetically (that is, Latin letters, multiple ≤). If the letters of syllables are the same, they are sorted by tone.
