Qī Jìguāng 戚繼光 (1528–1587), zì Yuánjìng 元敬, hào Nántáng 南塘, posthumously Wǔyì 武毅, was the most celebrated Late-Míng military commander, famed for his suppression of the wō kòu on the ZhèMǐn coast (1559–1567) and his subsequent reform of the northern frontier defences (1568–1582). Native of Pēnglái 蓬萊 (Shāndōng). His military reforms — based on training disciplined civilian-recruited qì jiā jūn 戚家軍 (“Qī family troops”) with new tactical formations and Western-influenced firearms — established the model for the late-Míng Chinese army.
