The word 打斗 is formed by combining two characters, each depicting a similar violent action, to create a single, more intense concept. The first character, 打, means to hit or strike. The second, 斗, depicts two figures clashing and means to fight or struggle. By placing them side-by-side, they merge into a single, dynamic idea of a physical fight or combat, visually and conceptually amplifying the sense of a violent, reciprocal exchange of blows.
