The Chinese Flag is a red with five stars. Red is the color of the revolution and was mirrored in the “little red book” that was passed out all over the place during Chairman Mao’s reign (The book was a collection of quotations from the Chairman.)
The large star represents the Communist Party. The four smaller stars represent the Chinese people. Apparently their yellow color indicates the bright future of the country.
For more information, check out the website where I got that graphic. It is located HERE and talks more about the symbolism of the flag.
