The very first flag on this blog will be the flag of South Korea. The Korean name of this flag is Taegukgi. This flag does not have long history on itself, but just like other flags it has been part of history with meanings to each part of the flag.
Taegukgi was made in late 19th century, through one event. In 1875, Japanese warship named ‘Unyo’ came close to costal sea of Incheon with their flag without Korean permission. This particular event brought first formal discussion about flag of the country. In 1883 January 27th in lunar calendar, King (or Emperor of Korean Empire) Gojong officially declared the flag of Korea, the Taegukgi. After this, people used Taegukgi a lot, but many times it was used in inappropriate ways. In 1948 Korean government standardized the figure of the flag. This Taegukgi have gone through Korean history since then, like March 1st movement.
Taegukgi itself symbolizes peace, unity, creation, light (bright hope), infinity, harmony and equality.
Taegukgi can be divided in to 3 parts, its background – white part, the middle – circle part, and side – the black parts. Each of them has its own meanings.
The background is all white, which shows ‘peace’. It represents the nationality of traditional patriotism, brightness, and purity.
On the center of the flag, there is a circle mark of Ying and Yang, which is called ‘Taeguk’ mark. This mark (symbol) is sign of harmony of Ying and Yang and truth of the nature in universe, like normal Ying and Yang mark does. However, the Taeguk mark is colored with red and blue; the upper part is colored with red and lower part with blue. Red in this symbol indicates Yang, nobility, upper part, and Left and blue will indicate Ying, hope, lower part and right.
Last part to explain is the black stripes on every corner of the flag. These stripes are called ‘goi’, and each four of them has their own name. The meaning of stripe symbols continues from the Taeguk circle. People usually call these stripes 4 goi, or ‘Gun Gon Li Gam’ their names. Starting from the left upper corner, then to opposite angle, then to opposite side, and right upper corner is order according to their name.
Each one has many meanings in many ways. Those ways are season, direction, nature, family, five elements and actual meaning. Gun shows spring, east, sky, father, gold and justice. Gon shows summer, west, earth, mother, soil, and prosperity. These two also means infinite development or growth together. Li represents autumn(fall), south, sun, son, fire and wisdom. Lastly, Gam will represent winter, north, moon, daughter, water and life force. Combind meaning of these to symbols is bright prospect, as characters are showing the sin and moon. All of these 4 symbols are solidified figure of change and development, using divination sign.
Korean government has organized the proper way to hang out the flag. In every national holiday like in January 1st, March 1st, and in august 15th, government hangs out Taegukgi in the streets to celebrate or to remember that day. Unfortunately, these days only very few amount of people are hanging the Taegukgi voluntarily. I believe each flag of every country as their nationality and all the flags should be cared by their onw people.
