笑说不再牵挂
[xiào shuō bù zài qiān guà]
Means 'Laughing and Saying No More Concern.' It indicates a resolution to let go and cease worrying or caring excessively about certain things or people. Coupled with laughter, it suggests doing so in a somewhat light-hearted manner, maybe after coming to terms with letting go, or as a protective barrier against further disappointment.
