The term is about appreciating and understanding the ideas in literary and

artistic works and the thoughts of their authors. The original meaning was

feeling a sense of resonance with music. It was later extended by literary critics

in the Wei, Jin, and Southern and Northern dynasties to mean resonance or

empathy between writers / artists and their readers / viewers. As a core concept

in literary criticism, it touches upon both general and particular issues in artistic

creation and appreciation, involves rich intellectual implications, and meshes

with the audience's response in Western criticism, receptive aesthetics, and

hermeneutics.
