你想哭却在笑你笑着掉眼泪
[nĭ xiăng kū què zài xiào nĭ xiào zhe diào yăn lèi]
Translated as 'You want to cry but you're smiling; you're laughing and dropping tears', which depicts an oxymoron - the complexity and ambiguity of human emotions. The user might feel joy mixed with sadness, masking sorrow through laughter, revealing bittersweet situations they go through.
