The red background symbolizes the revolution and the golden colours were used to "radiate" on the red background. The five stars and their relationship represents the unity of Chinese people under the leadership of the Communist Party of China. In the original description of the flag by Zeng, the larger star symbolizes the Communist Party of China, and the four smaller stars that surround the big star symbolize the four social classes (the working class, the peasantry, the urban petite bourgeoisie and the national bourgeoisie) of Chinese people.
