Democracy Wall

The Democracy Wall (Chinese: 西單民主牆(西单民主墙); pinyin: xī dān mín zhǔ qiáng) was a long brick wall on Xidan Street, Xicheng District, Beijing, which became the focus for democratic dissent. Beginning in October 1978, in line with the Communist Party of China's policy of "seeking truth from facts," activists in the Democracy movement—such as Xu Wenli—recorded news and ideas, often in the form of big-character posters (dazibao), during a period known as the "Beijing Spring". The first posting on the Wall was by a poet from Guizhou province named Huang Xiang.
