你的泪是我无法删去的回忆你的笑是我无法抹去的记忆
[nĭ de lèi shì wŏ wú fă shān qù de huí yì nĭ de xiào shì wŏ wú fă mŏ qù de jì yì]
Your tears are memories I cannot delete, your smile is memories I cannot erase. It expresses the deep impact that someone’s emotional moments—both painful and joyful—have had on the speaker’s life.
