The Korean national flag is called Taegukgi. Its design symbolizes the principles of 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 positive cosmic forces of yang. Conversely, the lower blue section represents the negative cosmic forces of yin.

The Korean national flag, Taegukgi is a symbol of peace, unification, creation, light and eternity.The Taegukgi has a taeguk, or yin(-) and yang(+), circle in the center and three bars at each corner. The taeguk circle (an ancient symbol of the universe) represents the great cosmic forces that oppose each other yet achieve perfect harmony and balance. The three bars in the corners represent the ideas of opposition and balance. The two forces together embody the concepts of continual movement and 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 white background symbolizes the purity, harmony and peace-loving character of the Korean people. In 1882, Park YongHyo used the Taegukgi for the first time and this was selected as the national flag in 1883

The national flower of Korea is the Mugunghwa or Rose of Sharon. It is beloved by every Korean for its beauty and perseverance. Every year from June to October a profusion of Mugunghwa blossoms grace the entire country. Unlike most flowers, Mugunghwa is remarkably tenacious and is able to withstand both blight and insects. The flower's symbolic significance stems from Mugunghwa's root word, "Mugung," meaning immortality. This word accurately reflects the perseverance and determination of the Korean people that has been demonstrated throughout their long history. Mugunghwa also means "endless" and thus represents the permanence of the Korean nation. The rose of Sharon symbolizes perseverance, endurance and long life and thus is a symbol of the Korean national character.
