Battle Born (novel)

This is the flag of the United Republic of Korea, as described on page 363:

There were two dark blue bars at the top and bottom of the banner representing the sky and strength of the earth. The white middle section symbolized the united land. The circle in the center, the t'aeguk, represented yin-yang, the power of opposites. Its red "yang" upper half, or positive side, represented life, goodness and fire; the lower "yin" blue half, or negative side, represented evil, death, darkness and cold. The two segments were entwined, meaning they could never be separated. Surrounding the center circle were the four broken-bar trigrams, taken from ancient Taoist and Confucian thought, representing virtuous ideals important to a long and happy life."
