Empress Gao
In spring 549, Emperor Xiaojing was forced to create Gao Cheng the greater title of Prince of Qi, and give him the honorific office of "Xiangguo" (相國), both signifying a move toward Gao's taking of the throne. Gao Cheng formally declined these honors, and further made a formal request for Emperor Xiaojing to create a son as crown prince. Subsequently, in fall 549, Emperor Xiaojing created his son Yuan Zhangren (元長仁) crown prince. (It is not known whether Yuan Zhangren's mother was Empress Gao.)
