Located in the center of Beijing, China, at the southern end of the Forbidden City, it is one of the first national key cultural relics protection units and one of China's national symbols. Mao Zedong's portrait hangs above the entrance in the middle of Tiananmen Square, with big slogans such as "Long live the People's Republic of China" and "Long live the great unity of the people of the world" on both sides.
