Recognition method of pictophonetic characters

1, phonetic inference method

Generally speaking, pictophonetic characters can infer initials or finals according to the pronunciation beside the sound, especially flat tongue (Z, C, S), tongue (zh, ch, sh), nasal sound (I), edge sound (I), nasal vowel (in, en) and nasal vowel (ing, eng, ong). The phonetic pronunciation of pictophonetic characters is basically the same as that of this word, such as flat, upturned, nasal, lateral, front and rear nasal vowels. For example, the initial of the word "Chen" is "Ch", the pictophonetic character next to the word "Chen" is also "Ch", and the vowels are nasal vowels-morning, pregnancy, vibration, fly and so on.

2. Point connection method

The so-called "dot" refers to the phonetic surface of pictophonetic characters, and "line" refers to pictophonetic characters with the same phonetic surface. We can connect many pictophonetic characters into a line, and spread outward with sound as a point to form a whole, which greatly improves the efficiency of memory accumulation. For example, pictophonetic characters with "Qian" as their pronunciation are roughly "jiān", "Xian" (qiàn, xiān) and "Qian" (qiān).

3. Remember the differences and discard the same method.

There are often some pictophonetic characters with the same sound surface, some of which have the same pronunciation and some are inconsistent. To this end, we can sum up those with the same pronunciation and then focus on remembering those with different pronunciations. For example, "pawn" reads zú, with phonetic characters, "_" reads zú, "sudden" reads Cü, "broken" reads Su, "quenching, smashing, refining, extracting, spitting, strain, Cui, _" reads Cu.
