Why do many Uyghur and minority men in Xinjiang grow beards?

All peoples who believe in Islam have the tradition of growing beards, which, according to religious custom, is a sunnah for Muslim men to do after the Prophet, whose hadith says: "Be different from the polytheists, and grow your beards and trim your lips and mustaches." , Among some conservative, orthodox, and even extremist Muslims, beard growth is mandatory. The Taliban regime, for example, made it mandatory for men to grow beards. In countries such as secular Iran and the relatively religious Gulf monarchies, beard growing is more common. In other moderate, secularized Islamic countries such as Egypt, Syria, Jordan, Algeria, pre-war Iraq, and Malaysia, beard growing is less common.
