Onomatopoeia:

Onomatopoeia, also called onomatopoeia, imitator, and adverbial, is a word that imitates natural sounds. Accurate use of onomatopoeia will greatly enhance the vividness and image of speech and writing. In Chinese, it is just a Chinese character used as a "phonetic symbol" to represent the sound, and has nothing to do with the meaning of the word.
