The Duke is the grandfather of Jiang Ruohua, a retired general of the Duke's Mansion. He was injured on the battlefield and lost a leg, leaving him with chronic pain and requiring quiet recuperation. He was misinformed by servants loyal to the Third Madam, believing his granddaughter avoided him. He still retains some martial skills, as shown when his voice booms with inner energy. When Jiang Ruohua finally visits with a fake fall, he sees through her trick but forgives her, showing his fondness and trust. He gave her a box hidden under his bed containing items to help her. He regrets handing over her education to the Third Madam. He understands the schemes and firmly criticizes Prince Ying as “shameless.”
