In the Wei dynasty, in the first month of the wushen year, the Emperor loathed Zheng Yan, Xu He, and others, and secretly issued an edict to Erzhu Rong to raise troops and march inward toward the court. Rong made Gao Huan his vanguard. When they marched as far as Shangdang, the Emperor again issued a private edict halting them. Zheng Yan and Xu He, fearing disaster would reach themselves, plotted to poison the Emperor. In the third month, the Emperor died suddenly. The Empress Dowager enthroned an imperial daughter as emperor, but then issued another edict declaring that she was actually an imperial daughter, and instead enthroned Zhao, the heir son of the late King of Lintao, Baohui, who was only three years old. When Erzhu Rong heard of this, he was enraged and said to Yuan Tianmu: "The late Sovereign passed away at nineteen years of age, yet the realm still referred to him as an infant monarch. How much more so to hold up a child who cannot yet speak to govern all under heaven! How could peace and order be sought thereby?" In the third month, Erzhu Rong and Yuan Tianmu welcomed the son of King Xuanwu of Pengcheng, King Ziyou of Changle, at Heqiao, where he ascended the imperial throne. He was called Jingzong and changed the reign era to Yong'an. Rong dispatched cavalry who murdered the Empress Dowager and the infant lord at Heyin (Beishi). "Erzhu" is a compound surname. Their ancestor was originally a great chieftain of the Qihu tribe, who served as a tribal chieftain generation after generation. They resided by the Erzhu River, and consequently took it as their surname.
