Qi Jiguang

Qi Jiguang recruited and trained a new army from the peasantry of Zhejiang province. He implemented strict discipline, innovative tactics, and specialized weapons, creating a highly effective force against Japanese pirates.

Qi Jiguang wrote 'New Treatise on Military Efficiency' (Jixiao Xinshu), a manual on military training and tactics. The book detailed his methods for organizing, equipping, and drilling troops, influencing later Chinese military thought.

Qi Jiguang led his army to a decisive victory against Japanese pirates at Cengang in Zhejiang. The battle destroyed a major pirate base and significantly reduced pirate activity along the coast.

Qi Jiguang was appointed to strengthen the Great Wall defenses against Mongol incursions. He rebuilt sections of the wall, added watchtowers, and trained garrison troops, improving border security for decades.
