虚心 (xū xīn) literally means 'empty heart' — combining 虚 (xū, 'empty, humble, not full') and 心 (xīn, 'heart, mind'). This evokes the image of an open, uncluttered mind ready to receive new ideas — like an empty vessel that can be filled. It describes a person who is modest about their own knowledge or abilities and genuinely willing to listen, learn, and accept feedback without defensiveness.

The term carries strong positive cultural weight in Chinese, especially in educational, professional, and interpersonal contexts. It’s often praised in teachers’ comments, leadership training, and self-reflection. While it can describe a temporary attitude ('be humble now'), it more commonly reflects a stable, admirable personal quality — similar to 'open-mindedness' in English, but with deeper connotations of moral humility and intellectual receptivity.
