Li Rusong
Li Rusong (1549–1598) was a Chinese general of the Ming dynasty who was from Tieling, Liaodong. He was the commander-in-chief of the Ming army in the first half of the Imjin War that took place in the Korean peninsula. Upon the request of the Korean King Seonjo of Joseon, the Ming Wanli Emperor sent reinforcements to support the Korean military in its war effort against the Japanese invasion masterminded by Toyotomi Hideyoshi. His father, Li Chengliang, who was also a Ming general, was known for defending Liaodong from the Jurchens. Based on historical documents, Li Rusong's 6th generation ancestor Li Ying (李英) was originally from Chosan (초산군 / 楚山郡) in present-day North Korea, however there are historical documents which state that the further ancestors of the Li family were from central China who moved to Korea during wartime.
