不要等我走后才说挽留不要等我哭后才说爱我
[bù yào dĕng wŏ zŏu hòu cái shuō wăn liú bù yào dĕng wŏ kū hòu cái shuō ài wŏ]
Don't say you want me back after I leave; don't say you love me after I cry: This implies the importance of expressing feelings honestly before it is too late, criticizing those who only show true emotions once others have reached a breaking point.
