Many of the nomadic herders in Kazakhstan left the USSR and moved to China in the 1920s. They feared being forced into collective farms by the Soviet state. Then in the 1950s many of them moved back again. Monica Whitlock has been listening to the story of Nazylkhan, a Kazakh herder and matriarch of a huge extended family, who lived through those epic journeys and who died in 2018.
