Tips
usage
wú appears chiefly in 鼯鼠 (flying squirrel — family Pteromyini), nocturnal squirrels with a patagium (skin flap) between fore and hind limbs that lets them glide between trees. The classical chengyu 鼯鼠之技 ('flying-squirrel's skills', from 《荀子》) describes someone with five mediocre skills and no real mastery: the flying squirrel can climb, swim, dig, run, and glide — but does none of them well. A polite put-down still used in formal writing.
culture
五灵脂 — the dried droppings of the flying squirrel — is a famous ingredient in traditional Chinese medicine, valued for treating blood stasis. It is paired with 蒲黄 in the classical formula 失笑散 (Sudden-Smile Powder, Song dynasty), so named because the medicine was said to relieve pain so suddenly that patients laughed in surprise.
