The Chinese word "热衷" (rèzhōng) is a compound verb meaning "to be fervently devoted to" or "to be passionate about", and its formation is a clear example of metaphorical and semantic synthesis. It combines the character "热" (rè), which literally means "hot" or "heat", with "衷" (zhōng), which refers to one's "innermost feelings" or "heart". Therefore, the term is constructed by figuratively applying the intensity and energy of physical heat ("热") to the core of one's emotions and intentions ("衷"), synthetically creating the concept of having a burning, heartfelt enthusiasm or dedication toward a particular activity or cause.
