所有的孤单者都是心冷
[suŏ yŏu de gū dān zhĕ dōu shì xīn lĕng]
'All Lonely People Are Cold-Hearted' is an exaggeration or generalization that associates loneliness with coldness or lack of emotion, implying those who appear aloof or emotionally detached because they often stay alone, whether chosen or unchosen. However, such loneliness may result from various complex reasons, not just heartless character.
