我不是无坚不摧的城墙我没有百毒不侵的心脏
[wŏ bù shì wú jiān bù cuī de chéng qiáng wŏ méi yŏu băi dú bù qīn de xīn zàng]
'I am neither an impregnable fortress nor invincible,' expressing vulnerabilities or admitting personal shortcomings in a world where toughness is often expected. It admits fragility, especially emotionally.
