心软是一种不公平的善良
[xīn ruăn shì yī zhŏng bù gōng píng de shàn liáng]
'Xin Ruan Shi Yi Zhong Bu Gongping De Shanliang', which translates to 'A soft heart is a kind of unfair kindness'. It suggests that the person believes having a soft heart means they are too nice for the sake of kindness and that could be deemed as unreasonable in certain situations.
