The word 走动 (zǒudòng) is formed by combining two individual characters, each with its own meaning, to create a new, more specific compound verb. The first character, 走 (zǒu), means "to walk", while the second, 动 (dòng), means "to move". Together, they form a word whose literal meaning is "to walk and move", but which is used idiomatically to signify activities like "to stroll about", "to move around", or, more socially, "to visit" or "to keep in contact by paying visits". This formation follows a common pattern in Chinese where two related verbs are paired to express a broader or more frequentative action.
