A renowned female general from the Northern Song Dynasty and one of the four great heroines of ancient China. In the 11th century AD, as the border of the Song Dynasty was on the verge of being breached by the Liao Dynasty's forces, Mu Guiying, a renowned general of the Song, led her troops in a charge that crushed the Liao army, thus beginning her legendary career in defending her nation. To address the military threats surrounding the Song Dynasty, Mu Guiying demonstrated the heroic spirit of shouldering the national burden, launching expeditions to protect her homeland. She masterfully commanded the Song forces in ambushes that severely damaged the formidable Liao army, averting the crisis of Liao incursions. Later, she led the Song army on campaigns against the Western Xia Dynasty, repelling enemy forces and slaying enemy generals time and again, earning distinguished service for the peace of the Song's borders. Beyond her victories in war, she treated captives with kindness, winning their allegiance to the Song Dynasty.
