人去楼空何必再念人走茶凉何必再恋
[rén qù lóu kōng hé bì zài niàn rén zŏu chá liáng hé bì zài liàn]
This lengthy saying can be summarized as 'Once they leave, the warmth is gone, why reminisce?'. It conveys a bittersweet reflection on relationships—acknowledging the impermanence of connections and accepting it with grace rather than holding onto past pains.
