National emblem: Tiananmen Gatetower under five stars, encircled by ears of grain and with a gear wheel below.

����On June 18, 1950, the Second Session of the First CPPCC National Committee adopted the design and illustration of the national emblem of the PRC. On September 27 that year, Chairman Mao Zedong ordered the promulgation of the national emblem. Composed of patterns of the national flag, the Tian'anmen Rostrum, a wheel gear and ears of wheat, it symbolizes the New-Democratic Revolution of the Chinese people since the May 4th Movement (1919) and the birth of New China under the people's democratic dictatorship led by the working class on the basis of the worker-peasant alliance.
