The word 共事 is formed by combining the character 共, which conveys the idea of "together" or "shared", with the character 事, which represents "matter", "affair", or "work". Conceptually, it directly merges the notion of collective participation with the domain of tasks or professional endeavors, creating a compound that encapsulates the idea of people joining in the same undertaking or sharing in work activities. The meaning emerges naturally from this fusion, picturing individuals united within a common sphere of action.
