世界太阔你的哭笑不只为我
[shì jiè tài kuò nĭ de kū xiào bù zhĭ wéi wŏ]
It conveys that the world is too vast and the other person’s range of emotions (both happiness and sadness) does not revolve solely around the speaker. This may suggest a sense of realization or acceptance about the limits of influence one has on someone else.
