He has dazzling silver pupils sparkling like shattered stars, a delicate and stunningly beautiful face described as rivaling Nuwa's craftsmanship, and pale skin. He suffers from chronic leg pain. He is described as a sickly beauty. After Cheng Youyou heals him with her ability, he is surprised by her changed behavior and scent, and his chronic ache eases significantly.
