东魏
In 534, Emperor Xiaowu, in a dispute with Gao Huan over the control of power, fled to the domain of the independent general Yuwen Tai, leading to a split of Northern Wei, as Gao Huan then made Yuan Shanjian the Heir Apparent of Qinghe emperor (as Emperor Xiaojing), and the areas under Gao Huan's control became known as Eastern Wei, and the areas under Yuwen's control became known as Western Wei. Gao Huan moved the Eastern Wei capital from Luoyang to Yecheng.
