The national flag of the People's Republic of China is the five-star red flag. The red color of the flag is the symbol of the revolution, signifying that the political power of the People's Republic of China is achieved through bloodshed and lives laid down by countless revolutionary martyrs who marched forward wave upon wave in the heroic struggles for the revolution. In the upper-left corner of the flag there are five-pointed yellow stars, of which the big one represents the Communist Party of China and the four small ones the people of all ethnic groups of the country.
