Zhongshan Metro Mall travels under about half a mile (815 meters) of central Taipei and runs parallel to the Red Line (Line 2, Tamsui-Xinyi Line). It connects Taipei Main Station to Zhongshan Station and Shuanglian Station as well as the MRT's corporate headquarters — officially the Taipei Rapid Transit Corporation — in a straight line and has a couple of important differences compared to the other malls.
One portion of the mall is mass market shopping, but it also has a portion that acts as a free art gallery of ever changing works. Another portion is a dedicated "Book Street" (originally part of a government initiative to encourage reading), and perhaps most impressively, the section of the mall immediately in front of the MRT's headquarters features a stage and an area for teenagers to practice "cheerleading" as well as other forms of dance. Consequently, the Zhongshan Metro Mall is more than just shopping. It's really an underground civic space.
