According to an analysis from The Guardian, over one-third of mosques and religious sites in China suffered "significant structural damage" between 2016 and 2018, with nearly one-sixth of all mosques and shrines completely razed.[91] This includes the tomb of Imam Asim, a mud tomb in the Taklamakan Desert, and the Ordam shrine at the mazar of Ali Arslan Khan.[92] According to The Guardian, Uyghur Muslims believe that repeated pilgrimages to these tombs would fulfill a Muslim's obligation to complete the Hajj.[91]
