Old Fourth is one of Yuan Shan's twin youngest sons. He and his brother eagerly help Yuan Tao unload wood when he visits. They are childishly excited at the sight of wild game, drooling and restless until the meal is ready. He is disciplined lightly by Yuan Tao for his impatience. He and Old Fifth often play in the courtyard, naughty but well-meaning, representing the innocent youth in the struggling family.
