How it's used
疾雷 is a literary expression that carries a sense of suddenness and intensity. While it is understood in Cantonese, it is rarely used in casual daily conversation, as speakers would typically prefer more common phrases like 快過閃電 or 閃電般. It appears most frequently in written contexts, formal speech, or when someone wants to add a dramatic or slightly poetic flair to their description of speed.
