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.
