Mongolia
The flag of Mongolia is a vertical tricolor with a red stripe at each side and a blue stripe in the middle, with the Mongolian Soyombo symbol centering on the leftmost stripe. The blue stripe represents the eternal blue sky, and the red stripes thriving for eternity. The Soyombo symbol is a geometric abstraction that represents fire, sun, moon, earth, water, and a Taijitu symbol representing the duality of yin and yang.
