武藝圖譜通志Muye Dobo Tongji : The Comprehensive Illustrated Manual of Martial Arts in Korea

【It is The official document at Korean Dynasty 】

The prologue : 我國練兵之制三軍練于郊衛士練于禁苑其禁苑練兵盛自光廟朝然止弓­­矢一技而已如槍劍法技，既未之聞焉

“Archery was the only martial art that had been practiced by Korean soldiers. They have no skills of sword or spear fighting”

購得戚繼光紀效新書遣訓局郎韓嶠遍質東來將士

Therefore, Koreans began learning sword skills and others from Chinese.

Almost all the Korean martial arts are copies from China or Japan.
