Dartsedo had a "reform through labor" prison or laogai after 1959. Jasper Becker in "" wrote, "The highest death rate was probably experienced by the Tibetans imprisoned after the abortive revolt of 1959. One survivor, Ama Adhe, describes in "A Strange Liberation: Tibetan Lives in Chinese Hands" what happened at the Dartsedo camp bordering Sichuan. By the roadside the authorities opened a mass grave which was filled with corpses and gave off a terrible stench. 'Every day,' she recalls, 'they would deliver nine or ten truck loads of bodies to put there...' Of the 300 women arrested with her, only 100 survived."
