The study looked at how ancient Chinese characters with radical components evolved over time, from oracle inscriptions to small seal characters and later publications. By analyzing these characters, researchers found that a large number of Chinese characters were created for radical use, forming a significant semantic field. This system helped ancient people pay attention to the meanings of words. The study used information from oracle inscriptions, modern Chinese dictionaries, and the book "Shuo Wen" to understand the cultural significance of these characters.
