Where did Wang move from Nandun Village, Chang 'an Town, Chengmai County, Hainan Province?

Wang's ancestor, Dagong, was born in Taicang, Jiangsu. He first moved to Putian County, Fujian Province, where he was Song Jieyuan and served as the chief defense officer. In the second year of Deyou in the Southern Song Dynasty (1276), he was transferred to the military affairs of the second government in Fang Qiong, and invited him to cross the river to Qionglai with his third son. Two years later, the Song Dynasty lost power. In order to survive in dispersion, Zong Dagong and his eldest son Chao Xi lived in Nandun Village, Chengmai with the official family.
