Muslims prepare beef in Altay, Northwest China's Xinjiang Uygur autonomous region for the Eid al-Adha festival, which is on the 10th day of the 12th month on the Islamic calendar. The festival marks the end of the haj and commemorates Prophet Abraham's willingness to sacrifice his son Ismail on God's command. China has more than 20 million Muslims, mainly living in the western provinces of Qinghai, Gansu and Yunnan, as well as Xinjiang. [Photo/Xinhua]
