Fangtian ji
Fangtian ji (Chinese: 方天戟, or Traditional Chinese: 方天畫戟; pinyin: Fāngtiān huàjǐ) is a term in Chinese cultural and literary tradition for a distinctive type of ji, a class of polearms that combine spear- and blade-like elements. In popular usage, fangtian ji is most commonly understood as a highly ornamented, halberd-like polearm, featuring a central spear point with additional symmetrical side blades on both sides, and is especially famous as the signature weapon attributed to the warlord Lü Bu in later retellings and fictions of Three Kingdoms period.
