Without resorting to any formulas, only 100 radicals are used which first grade pupils can learn to read and which are the most common in forming characters, The radicals, which are broken down from Chinese characters according to the order of strokes in calligraphy (handwriting), are arranged according to the order of the first phonetic letter of Chinese characters' phonetic transcriptions in the phonetic alphabet or the number of strokes.
