“Choi Hui-ryang, who was serving as the Goheunghyeongam of Jeolla-do at the time of Imjinwaeran (Japanese Invasion of Korea in 1592), reported to Admiral Yi Sun-sin, who was the then-Jeoldosa of the Left Jeolla-do Navy, and the Jeolla-do Gwanchalsa, on the victories against the Japanese forces from March 20 until July 12 of the 31^st year of King Seonjo’s reign. The documented reports were compiled together into Imnancheopboseomok (Collection of Books on the Intelligence during Imjinwaeran). The documents, which had been separate, were grafted together into a book by Choi Gi-jeong, a descendant of a patriot who was imprisoned for taking part in the March 1^st Movement.

Choi Hui-ryang, whose pseudonym was Irong and posthumous name was Musuk, was born in Naju. After passing the national examination for the military in 1594, he assisted Yi Gye-jeong, a naval officer of Chungcheong, in defending the country against the Japanese forces. Upon the outbreak of Jeongyujaeran (Japan's Second Invasion of Korea) in 1597, he was appointed as the Heungyanghyeongam. Under the leadership of Yi Sun-sin, he led his men to victory in the battles of Myeongnyang, Cheomsan and Yegyo, and he significantly contributed to the victory in the Battle of Noryang.”
