Sun Yat-sen briefly took a title of what Chinese military ranking?
Taewonsu Taewŏnsu (literally grand marshal, usually translated as "generalissimo") is the highest possible military rank of North Korea and is intended to be an honorific title for Kim Il-sung and Kim Jong-il. The rank is senior to that of "wonsu" (marshal). The title also exists in Chinese military history as "dàyuánshuài" (same Sino-Korean characters 大元帥), and was briefly taken by Sun Yat-Sen.
Prince Ding Prince Ding of the First Rank, or simply Prince Ding, was the title of a princely peerage used in China during the Manchu-led Qing dynasty (1644–1912). As the Prince Ding peerage was not awarded "iron-cap" status, this meant that each successive bearer of the title would normally start off with a title downgraded by one rank "vis-à-vis" that held by his predecessor. However, the title would generally not be downgraded to any lower than a "feng'en fuguo gong" except under special circumstances.
