There were also many Muslim settlements in the Jiangnan region, the area immediately south of the Yangzi river which was to become so important for the spectacular economic growth that China experienced during the Ming dynasty. Many of the Muslims who went to Yunnan with Mu Ying at the beginning of the Ming dynasty were drawn from the Jiangnan communities which, during the Yuan, included units of the Tammachi army and Muslim farming families.
A millennium later Mu Ying, one of Zhu Yuanzhang's close associates, brought an army to subdue the "eighteen lineages of the Tufan" in 1379. Many of his Muslim soldiers stayed at Taozhou, building the town's first mosque and setting up in trade between the nomads and the sedentary population of the Tao valley, Hezhou, and points north and east."

Together they "gradually created the new song form hua'er"
