无心人有心人不都是人

'Wú Xīn Rén Yǒu Xīn Rén Bù Dōu Shì Rén', meaning literally 'A heartless person, a considerate one - all are just people'. It suggests philosophical reflection on human nature and actions: despite their different levels of consideration, all people are the same, indicating a level of neutrality in perception or criticism towards oneself and others.
