The great Uighur poet Abduqadir Jalaidin has been in a Chinese internment camp for years. His former student, American historian Joshua Freeman, hadn’t heard from him, until recently, when a poem Jalaidin wrote inside the camps traveled by word of mouth to the outside world. Freeman speaks to The World’s host Marco Werman about the power of Uighur poetry and the future of Uighur language and culture.
