Chang'an Avenue is the road directly before Tian'anmen gate and to the north of Tian'anmen Square. Because of its location, Chang'an Avenue has been associated with a number of important events in Chinese history, such as the Tian'anmen Square protests of 1989 (including the famous confrontation of the Tank Man), the May 4th Movement and the funeral procession of Zhou Enlai. During important celebrations in the People's Republic of China, military parades are conducted on Chang'an Avenue, with the procession travelling from East to West along the avenue, passing before Tiananmen gate. For this reason, the avenue is surfaced with reinforced concrete, to prevent tanks and other heavy vehicle from damaging the surface.
