凉情凉心我百毒不侵没心没肺我活着不累
[liáng qíng liáng xīn wŏ băi dú bù qīn méi xīn méi fèi wŏ huó zhe bù lĕi]
Translating loosely into 'Indifferent heart and affection; nothing can hurt me emotionally because I am carefree and have no emotional attachment, hence living stress-free.' This implies a very resilient character, indifferent and not affected by any negativity in life.
