About the film
Letter from Masanjia is a Canadian documentary film, directed by Leon Lee and released in 2018. The film profiles the case of Sun Yi, a Chinese Falun Gong practitioner turned political prisoner who was responsible for exposing significant human rights abuses at the Masanjia Labor Camp when his letter was found by Oregon resident Julie Keith in a box of Halloween decorations, and made headlines worldwide. The discovery of this letter and the subsequent wide coverage by news agencies in part led to China announcing major reforms, and the abolishment of the labor camp system.
