心软是病哟
[xīn ruăn shì bìng yo]
In Chinese culture, the saying ‘Heart-softness is a disease’ means someone who is overly kind or too easily moved emotionally might get hurt. It's used here probably to show that the holder of this nickname believes that having sympathy and pity could sometimes become one’s flaw or bring trouble. The person possibly acknowledges their soft-hearted nature but still can't prevent it.
