一场戏累了小丑乐了观众
[yī chăng xì lĕi le xiăo chŏu lè le guān zhòng]
'One Play Tires the Clown but Makes the Audience Happy' refers to how performing sometimes makes actors exhausted despite entertaining others. A performer's hard efforts can result in exhaustion, but their performance delights people watching them on stage or screen.
