[2] – 14 May 558[3]), posthumously Empress Mingjing (明敬皇后), was the wife of the Emperor Ming (Yuwen Yu) of the Xianbei-led Northern Zhou dynasty.
It is not known when she married Yuwen Yu, although historical texts imply that it was after he became the Duke of Ningdu in 548.
A month later, Lady Dugu's father Dugu Xin, then the Duke of Wei, was implicated in a plot to kill Yuwen Hu with another high-level official, Zhao Gui (趙貴), the Duke of Chu, even though he tried to stop Zhao.
Zhao was executed, while Dugu Xin was relieved of his posts and subsequently forced to commit suicide.
On 22 February 558, Yuwen Yu created Lady Dugu "Heavenly Queen".
