The mǐ reading lives in a handful of high-impact compounds.
风靡 (literally 'wind-bends-down') = wildly popular, sweep through a population.
萎靡 (wilted-and-bowed) = listless, dispirited; a fixed compound for low mood or fading vitality.
披靡 (strewn-and-flattened) appears chiefly in the chengyu
所向披靡 'wherever pointed, the enemy is flattened' — a praise for an unstoppable force. Literary
靡 can also mean 'no; not', as in
靡不 (there is none who is not).
