An anti pig slaughter edict led to speculation that the Zhengde Emperor adopted Islam due to his use of Muslim eunuchs who commissioned the production of porcelain with Persian and Arabic inscriptions in white and blue color. Muslim eunuchs contributed money in 1496 to repairing Niujie Mosque. Central Asian women were provided to the Zhengde Emperor by a Muslim guard and Sayyid Hussein from Hami. The guard was Yu Yung and the women were Uighur. It is unknown who really was behind the anti-pig slaughter edict. The speculation of him becoming a Muslim is remembered alongside his excessive and debauched behavior along with his concubines of foreign origin. Muslim Central Asian girls were favored by Zhengde like how Korean girls were favored by Xuande. A Uighur concubine was kept by Zhengde. Foreign origin Uighur and Mongol women were favored by the Zhengde emperor.
