凉心冷情冷心无情
[liáng xīn lĕng qíng lĕng xīn wú qíng]
'Liang Xin Leng Qing Leng Xin Wu Qing' means 'cool-hearted, cold-feeling, cool-hearted again with no mercy'. It shows detachment, indifference or numbness of the person who had been hurt badly before, so much that he doesn't want any interaction and relationship anymore.
