history
A Song-dynasty proverbial couplet, widely attributed to folk poetry and adopted into classical drama. A well-known variant appears in Song poet Yang Wanli's (杨万里) work and later in operatic tradition. The phrase captures the zero-sum emotional arithmetic of events like imperial examinations, harvests, court verdicts, or market moves.
usage
