During the Khitan invasion of the state of Koryo in 993, So Hui was commander of the Second Army and organized the military defense of the state. As a result of successful negotiations, he obtained a pledge from the Khitans to leave Korea. In 994 and 995, So Hui subdued the Jurchens, who had occupied the region between the Chongchon and Amnok rivers, and built a defense line of six fortresses, which ensured Koryo’s control over the territory north of the Chongchon.
