The Chinese idiom "一举一动" (yī jǔ yī dòng) is formed through a parallel and complementary four-character structure common in classical Chinese. It combines two near-identical phrases: "一举" (one lift/movement) and "一动" (one action/move), where the numeral "一" (one) is used idiomatically to mean "every" or "each". The characters "举" (to lift, to act) and "动" (to move, to act) are synonyms that reinforce each other, creating a comprehensive meaning that encompasses every single action and movement a person makes. Thus, the compound word poetically and succinctly refers to one's entire behavior or all actions, highlighting the totality of conduct through a rhythmic, repetitive pattern.
