当我心是不锈钢而且防水吗
[dāng wŏ xīn shì bù xiù gāng ér qiĕ fáng shuĭ ma]
Literally 'Is my heart made of stainless steel, and waterproof too?' This phrase appears sarcastic questioning unrealistic expectations against oneself (especially emotionally), implying emotional strength but also pointing at vulnerability and human limitations.
