One of Sayyid Ajall Shams al-Din Omar's descendants, the Jinjiang Ding fled to Chendai (Jinjiang]] on the coast of Quanzhou to avoid the violence of the Ispah rebellion. The Li family survived through philanthropy activities however they said that in the rebellion "great families scattered from their homes, which were burned by the soldiers, and few genealogies survived." and used the words "a bubbling cauldron" to describe Quanzhou. In 1368 Quanzhou came under Ming control and the atmosphere calmed down for the Muslims. The Ming Yongle emperor issued decrees of protection from individuals and officials in mosques such as Quanzhou mosques and his father before him Ming Taizu had support from Muslim generals in his wars to reunify the country so he showed tolerance to them. The Ming passed some laws saying that Muslims not use Chinese surnames. Some genealogies of Muslims like the Li family show debate over teaching Confucian culture and classics like Odes and History or to practice Islam. Ming Taizu passed laws concerning maritime trade which were the major impact upon the life of Quanzhou Muslims. He restricted official maritime trade in Quanzhou to Ryukyu and Guangzhou was to monopolize south sea trade in the 1370s and 1403-1474 after initial getting rid of the Office of Maritime Trade altogether in 1370. Up to the late 16th century, private trade was banned.
