巿 (a ceremonial knee-apron, distinct from the look-alike 市 'market') is archaic and not used independently in modern Chinese. It survives as the phonetic in 沛 (abundant / Pei), 肺 (lung), and 芾 (luxuriant, in classical names).
mistakes
Do not confuse 巿 (one vertical stroke straight through, four strokes) with 市 'market' (a dot on top, five strokes). They look almost identical but are different characters.

ceremonial knee-cover
A small drawing of a cloth or leather flap hanging from a sash — the knee-apron worn at court. Treated as one pictograph; the hanging cloth is drawn as a single figure in 巿.
Filed under radical 巾 (jīn, #50) by convention. 巾 is not a separate component in 巿, so no strokes are highlighted.
