Because the city was built by the brothers Sun Juxiang and Sun Dingxiang, and Sun Dingxiang ranked third among the four brothers of the Sun clan, and served as the right deputy governor of the Ducha Yuan, his mansion was named "Sandutang". The ancient city of Yu is also called "the ancient city of three capitals".
