The Heart Flag of Mongolia, also known as the 'Mongolian Soyombo Symbol Flag,' is a significant national emblem consisting of a red background with a yellow square positioned toward the hoist and a blue field in the fly half. At the center of the red square lies the Soyombo symbol, an ancient Mongolian ideogram that represents the sun, the moon, fire, eternal life, and the five fundamental elements - sky, earth, water, minerals, and man. The Heart Flag serves as a powerful symbol of Mongolian identity and history, reflecting the nation's rich cultural heritage and unique place in the world.
