手shǒu

手 (shǒu, "hand") is a direct pictograph of a human hand with fingers spread, so visually accurate that it needs no explanation — three thousand years have only refined, never replaced, this ancient image. As a radical, it appears in over a hundred characters related to hand actions: 拿 (take), 抓 (grab), 推 (push), and 打 (hit), making it one of the most productive components in the Chinese writing system.
