Xidan (Chinese: 西单; Pinyin: Xīdān) is a major traditional commercial area in Beijing, China. It is located in the Xicheng District. The Xidan commercial district incorporates the Xidan Culture Square, North Xidan Street, as well as many supermarkets and department stores. The Xidan Cultural Square is the largest venue for cultural events with shopping nearby in downtown Beijing. Area Xidan occupies around 80 hectares (197.7 Acres) within the Xicheng District. Name The name Xidan (literally, "West Single") came from the paifang that existed on one of the streets there. In this context, the name "Xidan" refers to the single (单) paifang that existed on the west side (西) of the city. The paifang was rebuilt in 2008, and now stands at the Xidan Culture Square. History Xidan began to develop in the Ming Dynasty as an area alongside the passage for traders from Southwestern China to enter Beijing. Restaurants and shops were eventually built for these merchants. Eventually, as the Western part of the city became the residential area for officials, Xidan became a commercial area.

Xidan Wall Xidan Wall, also called Democracy Wall, is a long brick wall on Xidan Street. Erected in 1978, the event is generally recognized as the beginning of the Beijing Spring. Xidan Wall played a significant role in the democracy movement in Beijing during the summer of 1979. It was at that time where the wall received a significant number of posters that criticized China's leaders. Even an award-winning Canadian journalist John Fraser put up his own "dazibao," whose notice about a lost gold signet ring that concluded in vague political sentiment bizarrely resulted in his addressing the 1979 summer masses in Tiananmen Square.
