The flag of the Soviet Union is a red flag consisting of a sickle, a hammer and shining stars. The hammer symbolizes the working class; The sickle symbolizes the peasant class, and the combination of the two is the symbol of the workers-peasants alliance and the symbol of the * * * production party.

The stars not only symbolize the five fingers (labor force) of each hand of workers and peasants, but also represent "proletarians all over the world, unite!" Slogan. Red is the color of revolution, and yellow is the color of revolutionary light.

It should be noted that there is no sign of sickle and hammer on the back of the Soviet flag, only a pure red flag.
