你以为我心不锈钢还防水
[nĭ yĭ wéi wŏ xīn bù xiù gāng hái fáng shuĭ]
A witty expression meaning 'Do you think my heart is made of stainless steel and waterproof?' This net name suggests one’s heart isn’t impervious to damage and pain – it’s fragile instead of impenetrable. People do not realize it can also rust and leak from sadness and pain just as easily as normal steel and materials.
