The ji (pronunciation: [tɕì], English approximation: /dʒiː/ jee, Chinese: 戟; pinyin: jǐ) was a Chinese polearm, sometimes translated into English as spear or halberd, though they are fundamentally different weapons. They were used in one form or another for over 3000 years, from at least as early as the Zhou dynasty, until the end of the Qing dynasty. They are still used for training purposes in many Chinese martial arts.
