During the period of oracle,the semantic function of character components had come into being,but due to the components’ pictographic nature,the semantic function was not their main function.In the Warring States period,the pictographic nature disappeared,and the semantic function of the components was fully realized.The realization of the semantic function had a great influence on the formation and writing of Chinese characters.For Chinese character formation,the old components came to be used to generate new shapes,the formation ability and the structural level were improved,the formation and combination moved closer to a mainstream model,and Chinese characters became more systematic.For Chinese character writing,strokes were no longer limited to the description of images,and people could adjust the way of writing in accordance with the shape difference and writing convenience,which directly contributed to the production of strokes of Chinese characters,and the writing improvement of which further affected the formation of Chinese characters.
