Yin Tang is the ninth prince, known for being meddlesome and fond of teasing. When the brothers meet on the palace road, he immediately jokes with Yinxiang about being love‑struck, asking who has stolen his soul. He seems eager to stir up amusement at his brothers’ expense. He accompanies Yin Si and Yin E, and his light‑hearted provocations underline his personality as someone who enjoys gossip and mischief.
