South Korea
We begin in South Korea. Its flag is known as Taegeukgi, which means “Taegeuk flag.”
The Taegeuk is a red-and-blue circle (which Westerns would identify as a yin-and-yang). The blue represents negative forces and the red positive, balancing each other out to create perfect harmony.
There are also four trigrams in each corner of the flag, which are said to represent earth, fire, water, and heaven as well as the cardinal directions and family members. The basic building blocks of life, no?
The symbols are on a white background, which represents land and peace.
