What does the flag of South Korea mean?
South Korea's flag centers on the taegeuk, a red-and-blue circle representing the balance of opposing cosmic forces, yang (the red half, positive energy) and yin (the blue half, negative energy), against a white field said to represent peace and purity. Around it sit four black trigrams drawn from the I Ching, each built from three broken or unbroken lines and each paired with one of the classical elements, heaven, earth, fire and water, along with associated virtues. Together the circle and trigrams are meant to express harmony and constant movement rather than a fixed, static state.
