According to World Atlas, the large star on the flag of the People's Republic of China represents the Communist Party, while the smaller stars represent the four social classes of China. These classes were the workers, the peasants, the petty bourgeoisie and the bourgeoisie.
Mao Zedong designated these classes in a speech titled "On the People's Democratic Dictatorship." The designer of the flag, Zeng Liansong, came up with the idea to use stars one night when he remembered a proverb: "longing for the stars, longing for the moon." This expression of deep yearning reflected the desire of the Chinese people for freedom, so he incorporated stars into the flag. He chose yellow so that the color would contrast against the bright red background.
