摸着胸口说不疼捂着心口说不痛
[mō zhe xiōng kŏu shuō bù téng wŭ zhe xīn kŏu shuō bù tòng]
The phrase literally translates to 'Saying not hurt while pressing the chest, saying not pain while covering the heart.' It humorously describes a situation where someone tries to pretend everything is fine even though they are in pain, often used to portray resilience or a façade of strength.
