Why can't you believe the sentence "a scholar knows half a sentence"

There are a large number of pictophonetic characters in Chinese characters. This kind of word consists of two parts: one part represents the meaning of the word and is called the shape edge; The other part represents the pronunciation of words, which is called the phonetic symbol surface. For example, the word "Ping" is composed of the word "Feng" beside the shape and the word "Ping" beside the sound. "Feng" means "Ping" is related to plants, and "Ping" means "Ping" pronounced "píng". There are many pictophonetic characters with "ping" beside them, such as: ping, ping, ping and pestle. You may not know these words, but according to the characteristics of word formation, you can pronounce them as "píng". But some words, such as "bang" and "bang", are all wet if you pronounce them as "píng" again. They should be "pēng". Chinese characters, also composed of "Ping", have different pronunciations. This is because the phonetic symbols of Chinese characters are phonetic components, but the Chinese syllables they represent are similar, not completely accurate, and different from syllable letters. Moreover, phonetic symbols also have a conventional nature, that is, Chinese characters with the same pronunciation are often represented by different phonetic symbols. For example, if you all read "J:", you can write different words such as "base", "muscle" and "chicken". Therefore, when learning Chinese characters, we should find out the accurate pronunciation of each word, and we can't just look at the syllables beside the sound and think it is the pronunciation of this word. The statement that "a scholar knows half the story" is not credible.
