The flag of China features a red field with five yellow stars in the top left corner. The larger star represents the Communist Party, while the four smaller stars symbolize the four social classes: the working class, the peasantry, the urban petite bourgeoisie, and the national bourgeoisie. The stars are arranged in a way that reflects the unity of the Chinese people under the leadership of the Communist Party. Adopted on October 1, 1949, the flag's red background signifies the communist revolution and the bloodshed in the struggle for liberation. The design embodies the country's aspirations for unity and strength.
