Leon Lee's 2018 documentary Letter from Masanjia documents the journey of an SOS message found in Halloween decorations by Oregon mother Julie Keith, which exposed severe human rights abuses in a Chinese labor camp. The film, featuring author Sun Yi, highlights the brutal conditions, forced labor, and torture experienced by Falun Gong practitioners, ultimately contributing to the abolition of China's Re-education Through Labor system.
