Brief introduction of radicals:
Radical is the word-forming component of compound words. The ancients called the left and right sides of Chinese characters with left and right structures "pian" and "bian". Now, all parts of the combined Chinese characters are collectively called parallel.
Chinese characters are mostly pictophonetic characters, which are composed of pictophonetic characters and homophonic characters. Therefore, "radical" mainly includes pictophonetic characters and homophonic characters. For example, the word "Yu" consists of two radicals, Yan and Wu. The word "basin" consists of two radicals: "fen" and "pan bottom"; The word "Wen" consists of two radicals: the door frame and the mouth.
