The elegance of thirty-six letters

China's phonological terminology. Pinyin refers to the representative words of Chinese initials. The word letter comes from the Sanskrit Modo (Sanskrit mata). Sanskrit Modo originally refers to vowels, but later the meaning of Sanskrit has expanded, and the consonants are also called Modo. After the word was introduced into China, phonologists only used it to represent initials. Before that, there was no special name for initials in China. People use two syllables to represent initials, and the two syllables of the upper word and the incised word indicate that the two words have the same initials. At the end of the Tang Dynasty, inspired by the Sanskrit alphabet, monks assigned a representative word to each sound category, which is the alphabet. The remnants of letters unearthed in Dunhuang are listed as "not fragrant and not bright ..." with 30 letters. Later, some people "benefited from the humble service of the mother bed country", with a total of 36 letters. In the traditional phonology of China, it is also called "36 warm letters" and "warm letters". "Letter" is the first letter. The old legend is the 36 representative initials created by Shaman Wenshou at the end of Tang Dynasty. People can trace back to the ancient initials system through this set of letters, and they can also study the current dialect pronunciation to explain the law of phonetic development. These thirty-six letters were actually supplemented by the Song people according to the thirty letters at the end of the Tang Dynasty (see "The Legacy of Warm Rhyme"), which reflected the phonetic system of the Song Dynasty.
