How are the three sections divided?

Three pinyin, there is a mother, her tongue seems to be dancing. The initial is light, but the initial is fast. Vowels can't be put outside. I lost my mother. Just kidding, the red flower turned red.

1. In Chinese Pinyin, there is a sound between the initial and the final, which is called the intermediate sound. In spelling, the initial consonant is connected with the vowel "I, U, ü" as an intermediate sound, and then connected with other vowels. Spell a syllable quickly in one breath.

2. Three-syllable structure: initial+middle vowel (i /u /ü)+ vowel.

For example: melon: from G (initial) +u (middle) +a (vowel). ?

Three short stories of Pinyin Festival:

In this big tribe of syllables, there are two families of initials and finals. The children of initials and finals who live in these two houses are very kind and friendly. Some will hold hands when they meet, and some will not know each other when they meet.

The initial sh is walking, and then the vowel o comes. They don't know each other, and the vowel U, which is widely communicated, comes. He pulled Sh with his left hand and O with his right hand, pulling them all to his side and forming a new family.

There is a consonant and two vowels, among which vowel U is called intermediary because it is intermediary, and this syllable is called trisyllable.
