The Chinese word "人潮" is formed by directly combining the character "人" (rén), meaning "person" or "people", with the character "潮" (cháo), meaning "tide" or "wave", where "潮" acts as a metaphorical element to visually and conceptually represent a large, moving crowd, resulting in a term that literally translates to "human tide" to describe a dense, surging mass of people.
