Origin Story
梁武帝萧衍非常欣赏到荩的才华，经常在一起吟诗作赋。一次，萧衍写了一首诗送给到荩，其中有句“如飞蛾之赴火，岂焚身之可吝”。诗中运用飞蛾扑火作比喻，形容到荩虽然知道这样做有危险，但是依然义无反顾，勇往直前，为了理想而牺牲自己。后来，这句话被人们引用，成为一个成语，用来比喻不顾一切的追求，即使明知危险也在所不惜，最终导致自取灭亡。
Emperor Xiao Yan of the Liang Dynasty greatly admired Dao Jin's talent and often composed poetry together. Once, Xiao Yan wrote a poem for Dao Jin, which included the line "Like a moth to a flame, how could one lament one's own life?" The poem uses the metaphor of a moth flying into a flame to describe Dao Jin's unwavering courage, willing to sacrifice himself for his ideals, even if it was dangerous. Later, this phrase was used as an idiom to describe someone who pursues something relentlessly, even if they know the risks, ultimately leading to their own demise.
Usage
