Дин Жучан
In July 1882, in what was known as the Imo Incident in Joseon Korea, then still a traditional Chinese protectorate, units of the Korean military revolted in Seoul. In part, the flare-up of violence may have been caused by provocative policies and conduct by Japanese military advisors training the new Special Skills Force. Xue advised Li to take quick action to put down the rebellion. The Chinese dispatched Beiyang Naval Units under the command of Ding Ruchang to Joeson to assess the evolving situation. Chinese troops effectively quelled the rebellion. The pro-Japanese Regent Daewongun, accused of fomenting the disturbance and its violence, was arrested by Chinese troops and taken to China where he spent three years in custody and only returned to Korea in 1885. The incident was regarded by the Chinese as a Japanese plot to assert control over Korea. Xue received a promotion because of his advice to take quick action in putting down the rebellion.
