再痛再苦也说没事
[zài tòng zài kŭ yĕ shuō méi shì]
Translated as 'Even if it hurts terribly, still say it’s fine', this shows resilience in the face of pain or difficulty. No matter how much someone suffers inwardly—be it physical agony or mental anguish—they remain tough and do not let external parties know how badly they are hurting.
