According to "Dafeng County Records", the Ding surname in Song Dynasty mainly migrated from Zhejiang. At that time, there was a man named Ding Pu in Zhejiang. Because his family was poor, he came to Shen Zao with his wife and two sons. He reclaimed wasteland in Shen Zao, planted rice and vegetables, and established a small village. His two sons, Ding Jing and Ding Lin, inherited their father's diligence and frugality, and gradually developed and expanded their family. Their descendants took Shen Zao as their ancestral home and formed a branch of Shi Ding, Shen Zao. To sum up, Yancheng Dafeng Ding Shi migrated from Zhejiang in the Song Dynasty.
