People's Republic of China (PRC)'s national flag is red, symbolizing the revolution. The big five-pointed star in the national flag represents the China * * * production party, and the four small five-pointed stars represent the workers, peasants, petty bourgeoisie and national bourgeoisie respectively. Each of the four little stars has a tip facing the center of the big star, and the positional relationship between them symbolizes the great unity of the revolutionary people under the leadership of the China Production Party. The five stars glow in yellow on the red soil, which also means that the Chinese nation is yellow.
Red symbolizes revolution, and the blood of martyrs is red.
