The heir of the Wuyang Marquisate, who was once engaged to Yan Cunzhen. He was a talented inventor who created the Curved Shaft Plow, Waterwheel, and Honeycomb Briquette, and was also a renowned poet. However, he was a cut-sleeve who kept male favorites, particularly Su Nu. When Yan Cunzhen punished Su Nu, he demanded she behave with magnanimity or face widowhood, leading to her castrating him. He was subsequently stripped of important duties by the emperor.
