The Chinese word 火热 (huǒrè) is formed through the compounding of two independent characters: 火 (huǒ), meaning "fire", and 热 (rè), meaning "heat". It follows a common morphological pattern in Chinese where two semantically related nouns or adjectives are combined to create a new, often metaphorical, adjective. Literally, it denotes the intense heat of fire, but its primary meaning is figurative, describing a state of extreme passion, popularity, or fervent activity, thus, the formation is both compositional (fire+heat) and idiomatic, conveying a vivid sense of intense, burning enthusiasm.
