The 国旗 is one of the most sacred and visible symbols of the People's Republic of China. Its official name is the “Five-star Red Flag” (五星红旗 - Wǔxīng Hóngqí).
Symbolism: The design is deeply political and historical. The red background symbolizes the communist revolution and the blood of the martyrs who died for it. The large yellow star represents the leadership of the Communist Party of China (CPC), while the four smaller stars represent the four social classes (workers, peasants, urban petty bourgeoisie, and national bourgeoisie) united under the party's guidance.
National Pride and Unity: The flag is a powerful vehicle for patriotism (爱国 - àiguó). It is raised daily in schools and government buildings, and its presence is overwhelming during national holidays like National Day (国庆节). For many Chinese citizens, the flag represents China's journey from the “century of humiliation” to its current status as a major global power.
Comparison to Western Culture: In the United States, the “Stars and Stripes” is also a revered symbol of national identity. However, its use can be more personal and varied—it's flown by individuals on their homes, used in political campaigns by all parties, and sometimes even incorporated into fashion. In China, the use of the 国旗 is more formal and state-controlled. The National Flag Law (《中华人民共和国国旗法》) dictates its proper use and strictly prohibits its desecration. It is seen less as a symbol for personal political expression and more as a representation of the unified state and the ruling party.
