Syllable meaning
Zi, ci and si: The vowels of these three syllables are not the common vowel I, but the pre-vowel -i (corresponding to the international phonetic symbol []), which is difficult to master. In order to avoid the difficulty of learning vowels before the language, it is necessary to recognize these three syllables as a whole.
Ye: This syllable can be regarded as a self-contained syllable of vowel ie, and it can also be regarded as a syllable composed of initial Y and vowel Mi. According to previous understanding, in order to avoid teaching spelling rules, it should be regarded as a whole ("Scheme" stipulates that vowel ie has its own syllable, so I have to change it to Y); According to the latter understanding, it is recognized as a whole in order to avoid the semi-low vowel "mi" before teaching the tongue (the corresponding international phonetic symbol is [? ])。
