"旗" (qí) is the Chinese word for "flag." Flags are pieces of fabric, often rectangular, that display specific colors, patterns, or symbols. They are used to represent countries, organizations, or movements, serving as a visual symbol of identity and unity. Flags can be seen in various contexts, such as national celebrations, sporting events, and military displays. In addition to their symbolic meanings, flags also have practical uses. They can signal information, such as in maritime communication, where different flags indicate specific messages. The design and colors of a flag often hold historical significance, reflecting the culture and values of the entity it represents, like the United Nations or Olympic Games.
