Jingtang Jiaoyu was founded during the era of Hu Dengzhou 1522–1597.[63] Other provinces had different systems and different specializations; Lintao and Hezhou provinces had a three-tier educational system in which the youngest children learned the Arabic required for namaz and wudu, and then graduated to more advanced studies. Shandong province became a center specialized in Persian texts. As the Hui Muslim community became more diluted, Chinese scholars worked harder to translate texts into Chinese to both provide more texts for Muslims to convince the ruling Han elite that Islam was not inferior to Confucianism.[64]
