The Korean flag is called "Taegeukgi" in Korean. Its design symbolizes the principles of the yin and yang in Oriental philosophy. The circle in the center of the flag is divided into two equal parts. The upper red section represents the proactive cosmic forces of the yang. Conversely, the lower blue section represents the responsive cosmic forces of the yin. The two forces together embody the concepts of continual movement, balance, and harmony that characterize the sphere of infinity. The circle is surrounded by four trigrams, one in each corner. Each trigram symbolizes one of the four universal elements: heaven, earth, fire, and water.

The national flower of Korea is the Mugunghwa, rose of sharon. Every year from July to October, a profusion of Mugunghwa blossoms graces the entire country. Unlike most flowers, Mugunghwa is remarkably tenacious and able to withstand both blight and insects. The flower's symbolic significance stems from the Korean word mugung, meaning immortality. This word accurately reflects the enduring nature of Korean culture, and the determination and perseverance of the Korean people.

It is widely acclaimed by linguists as an ingenious invention.
