fú is strictly archaic — a technical term in classical ritual dress. It names one of the Twelve Ornaments (
十二章) embroidered on the emperor's and senior officials' ceremonial robes: pairs of interlocking
弓-shaped lines in black and blue, symbolising the discrimination of right and wrong (the back-to-back
弓 figures suggesting two parties facing off in judgement). The compound
黼黻 names the pair of axe-pattern +
弓-pattern ornaments together, and the phrase
黼黻文章 came to mean splendid literary composition. Modern Chinese readers meet
黻 only in classical texts, art-history writing, and discussions of imperial regalia.
