人潮拥挤只为拆散我和你
[rén cháo yōng jĭ zhĭ wéi chāi sàn wŏ hé nĭ]
Expressing a melancholic sentiment that amidst crowded places, it's almost as if everything around conspires to separate two individuals. It suggests the sadness of being unable to stay together when faced with overwhelming circumstances or obstacles.
