The main religions in Qinghai are Tibetan Buddhism and Islam. The Dongguan Mosque has been continuously operating since 1380. Measures of education in Qinghai are low, particularly among the Muslim ethnic groups such as the Hui and Salar, who sometimes prefer to send their children to madrasahs rather than secular schools. The yak, which is native to Qinghai, is widely used in the province for transportation and its meat. The Mongols of Qinghai celebrate the Naadam festival on the Qaidam Basin every year.
