There is a character “셓” in the inscriptions on bronze wares of Shang and Zhou Dynasties, and up to now, the academic community is divided on the reading of this character. From the use cases where the character appear in the inscriptions on ancient bronzes, it is used as the appellation of the clan without exception, mainly as the single clan name, and then as the constituent of the compound clan name. However, why the clan is named as “셓” and what is the meaning of its configuration have been rarely mentioned. Combining the latest research results of the history and culture of ancient society and archaeology with the inspection and proofreading of the related words of this character, besides versifying with the handed down literature the paper, the paper holds that the character is actually related to the fishery production in ancient times as the symbol of the clan. The configuration of “셓” is the reflection of an image in which a caught fish is disemboweled and then stretched out by bamboo or branches to dry. And the structural meaning is “薧” corresponding to “鱻”, also known as “鱐” in the literature handed down from ancient times “The Three Rituals”, namely the dried fish said today.

This article conducts a multidimensional quantitative data analysis of writing scores and related variables such as word frequency, stroke number, and the number of components in the corpus of Chinese character acquisition of primary Chinese learners from non-Chinese culture circles, and then analyzes the cognitive characteristics and rules of Chinese character acquisition reflected in the data from the perspective of cognitive psychology. Data analysis shows that there are “stroke number effect” and “component number effect” when learners write Chinese characters, and the influence of the stroke number and component number on writing depends on the level of Chinese characters in the whole book frequency, and the dividing line is about 200. From the perspective of cognitive rule, frequency, stroke number and component number affect the whole process of perception, memory and extraction of Chinese characters. There are differences in the recognition methods of Chinese characters with different frequencies when writing. Learners use compressed and holistic recognition for high-frequency words (frequency>200), while partial and feature recognition for medium and low-frequency words (frequency≤200), and the basic units of feature recognition are strokes and components.The score of wrongly used characters is not significantly correlated with frequency, strokes and components, and the cognitive rules reflected by wrongly used characters need further study.
