The phrase "怎么办" is formed through a direct and logical conceptual combination: the interrogative element "怎么" (meaning "how" or "in what way") is placed immediately before the verb "办" (meaning "to handle" or "to do"). This structure creates a single, indivisible unit of meaning that literally queries the method or course of action for dealing with a situation, evolving into a common expression equivalent to "What should be done?" or "How to handle this?". Its formation is essentially the fusion of a question about manner with an action verb, resulting in a standard idiom for expressing a dilemma or seeking a solution.
