爱笑不为我
[ài xiào bù wéi wŏ]
The meaning here is 'Laughing is not just for my sake.' This suggests someone who has learned or chosen not to depend on external factors or approval (like laughter or smiles from others) to gauge self-worth. They laugh freely, live genuinely, and do not confine their joy only to specific persons or situations, reflecting a more open-hearted outlook on life.
