1. phonetic notation: phonetic notation is used for phonetic notation. You can't pronounce without homophones. If they are more difficult to read than phonetic notation, they have no phonetic notation. Such as: father Yin Fu.
2, reading if the law: using analogy to phonetic Chinese characters, that is, reading like a word sound. Such as: Song, read and send; Reading is like a flower
Ye Yinfa: It is wrong to change the pronunciation of a word temporarily for rhyme: it is unfounded to change the pronunciation of a word subjectively and strongly. Such as: Shuo Shuo Shuo, no food for me. "Wheat, leaf sound mouse".
4. Backcutting method: Annotate another Chinese character with two Chinese characters. The former is called backcutting the upper word, the latter is called backcutting the lower word, and the phonetic notation is called cutting the word. The relationship can be expressed as: word cutting = reverse cutting of upper word+reverse cutting of lower word.
5. analogy: it is a method of comparing and explaining similar things.
