心软是病而且没药治
[xīn ruăn shì bìng ér qiĕ méi yào zhì]
This nickname means 'being soft-hearted is a sickness with no remedy.' In Chinese culture, it suggests that being overly sympathetic or compassionate can be seen as a weakness and sometimes gets oneself into trouble, implying the need for more toughness or assertiveness in certain situations.
