心你别痛痛了就输了
[xīn nĭ bié tòng tòng le jiù shū le]
It translates to 'Heart, don't be in pain; if it hurts, you lose.' This indicates that when faced with difficulties or emotional pain, it's important not to let oneself be overtaken by negative emotions because once the heart feels the pain, one might succumb to despair or lose control over oneself emotionally.
