Its deeper meaning emphasizes obtaining maximum benefits at minimum cost, and it often appears in scenarios such as strategic planning, resource allocation, and daily life. This idiom originates from the Book of Jin and carries a clearly positive connotation, reflecting the ancients' admiration for wisdom and efficiency. When used, it mostly refers to positive and constructive results, such as saving both time and money, or both exercising the body and uplifting the mood. In terms of cultural background, it reflects the practical rationality in Chinese culture that advocates "achieving twice the result with half the effort." It is similar in meaning to "one arrow, two hawks" and "achieve twice the result with half the effort," but places more emphasis on the clear gains of "two benefits." Emotionally, it conveys a tone of satisfaction, appreciation, or encouragement, and is often used in suggestions, evaluations, or summaries. It should be noted that it is usually not used for negative meanings or accidental gains, but emphasizes the dual benefits brought by active choice.
