work, matter, happening

事 is a pictograph depicting a hand holding a tally or symbol. The tally, a credential used by envoys or high-ranking officials to pass through city gates or checkpoints, was inscribed with text and typically split into two halves that were matched when used. In ancient times, leaving the city to visit other countries was an important task, as represented by 事. Additionally, 事 (affair), 史 (history), and 吏 (official) share the same origin, with closely related forms and meanings, indicating their deep connection.
