What do the two broken bars with one solid bar in the middle represent in the Korean flag?

The two broken bars with one solid bar in the middle on the Korean flag represent the concept of water in the context of the I Ching, or the Book of Changes, which is foundational to the philosophy underpinning the flag's symbolism. In this representation, the solid bar symbolizes the Yang aspect, while the broken bars signify the Yin aspects.

This balances the duality of elements in nature, where the solid bar (Yang) represents stability and strength, while the broken bars (Yin) represent fluidity and adaptability. Water is essential in many philosophical interpretations, signifying life, flexibility, and the ability to take various forms, enhancing the idea of harmony and balance.

The other elements (wind, fire, earth) are represented differently in various cultural symbols and philosophies, but in the context of the Korean flag, the two broken bars specifically denote the element of water and its essential qualities in relation to nature and existence.
