Among the 74 radicals in Shuowen Jiezi,which only lead one ideograph,the 30 radicals are created according to the need of grouping,and the relationship between the radicals and the characters within the radicals is interdependent.The grouping of merged ideographs into radicals follows the principle of harmonization,the processing of compound ideograms follows the principle of harmonious classification and arrangement style.While grouping the 30 ideographs,the method lies in discarding the existing radicals in the ideographs and creating an additional one,thus harmonizing the grouping of ideographs and the meaning symbols that act as the heads of the characters in the ideographs.The selection and establishment of radicals are constrained by the unified arrangement style of Shuowen.
