4. Cultural Background and Notes

• The idiom originates from the Book of Changes (诗经), specifically the 'Li' hexagram, which described a sudden, violent arrival like fire or death. While it originally had a very ominous connotation, in modern Chinese it is used more neutrally to describe any sudden event, whether good or bad.
• Grammatically, it most often functions as an adjective (attributive) followed by the particle 的 (de), as in 突如其来的 (tū rú qí lái de), to modify a noun.
