The work was created in Oberhausen, Germany, for the residency programme of Oberhausen Film Festival and was inspired by Zinkfabrik Altenberg (zinc factory, part of the Rhineland Industrial Museum), a museum that presents collections from the pre-war to the present history of industry in the Ruhr region. In Sun Xun’s works, he keeps experimenting with diverse media, from painting to woodcuts, traditional Chinese ink and three-dimensional models to coal drawings, collages and more. His work revolves around history as filtered by the media, the contradictions between official historiography and personal experience. “I have two means of encountering history: either through school education or oral history recounted by my grandmother and my father. The version of history taught in school has an obvious political assertion, while oral history comes from individuals’ memories, which can also be distorted. In this way, history often embodies prejudice from different cultures, nations, political parties or individuals.” (Sun Xun).
