难过从来就不能解决问题
[nán guò cóng lái jiù bù néng jiĕ jué wèn tí]
It refers to 'Being Sad Can Never Solve the Problem', representing a rather mature, realistic view of expressing emotion. It means we need positive action and courage instead of being overwhelmed in grief. Of course, the mood may also carry a helpless sigh, implying even if I'm so sad because the problem remains unresolved. The latter is closer to Chinese popular sentiment and thinking.
