It lies at the final level of the stroke-component-character Chinese character composition.
[9] The first-level component combination mode or pattern is what people often call the structures of Chinese characters.
According to this analysis, the structures of decomposable characters can be divided into 4 major categories and 13 subcategories:[10][11] Full surround: Surrounded from three sides: Surrounded from two sides: The following data is excerpted from Chinese Character Information Dictionary, with 7,785 Chinese standard characters.
According to the planar analysis by primitive components, Chinese character structures include the following modes or patterns:[13] The level to which Chinese character components should be divided must be determined based on specific needs.
For example, Chinese character teaching often uses a coarser level of analysis in order to be concise, while component-encoding Chinese character input methods often use relatively detailed analysis in order to reduce coding elements.
In both dynamic and static distribution statistics, more than 99% of the characters have less than 5 primitive components.
