Rarely stands alone in modern Chinese — almost always in compounds: 旗帜 (qízhì, flag/banner), 独树一帜 (dúshùyīzhì, to set up a unique banner = to be original), 别树一帜 (similar).
memory
巾 'cloth' radical + 只 phonetic. The cloth radical hints at flags (also seen in 帆 'sail', 幕 'curtain'). Famous from《史记》: 拔赵帜,立汉赤帜 — Han Xin's troops swap the Zhao banners for red Han banners to fake a complete victory.
