Authorities in China's Xinjiang region are threatening to detain residents over downloading, listening to and sharing Uyghur-language songs they consider sensitive.

It is a soulful folk song, filled with feeling and history: A love-stricken young man tells God about his hopes and dreams of happiness. Generations of Uyghurs, the Turkic ethnic minority in China’s Xinjiang region, have played it at parties and weddings.

But today, if they download it, play it or share it online, they risk ending up in prison.
