How to distinguish between structure, radicals and strokes

The various specific dots and lines that make up the shape of a Chinese character are also the smallest structural unit of a Chinese character. According to the requirements of the Regular Script, a stroke is defined as a single stroke from the time it is placed to the time it is lifted, which is also called a stroke, and the specific shape of the stroke is called the stroke form.

The radicals, also known as components, are the basic units of a Chinese character made up of strokes.

When compiling dictionaries, characters with the same radicals are grouped together and called a part, and this same radical is called a standard, and is listed as the first character, which is called the radical. East Han Xu Shen "Shuowen Jiezi" first cause,*** 540 radicals, and later gradually reduced, "Chinese unified radicals table (draft)" (1983), 201 "Table of Commonly Used Characters in Modern Chinese" 201.
