Flag of Surea

The flag of Surea, or San'yunhiki (三元日旗; "three element sun flag") was taken from the Chinese design of the taichi symbol and has two parts: a white background and a red, blue and yellow San-Daichi ("Sam-Taegeuk") in the center.

The general design of the flag derives from traditional use of the tricolor symbol (red, blue and yellow) by Sureans starting from the early era of Surean history. The white background symbolizes "cleanliness of the people." The San-Daichi represents the origin of all things in the universe; holding the principles of "Heaven", "Earth" and "Humanity", in perfect balance. Together, they represent a continuous movement within infinity, the three merging as one.

The san-daichi, when stand as a circle alone, represent the sun, incorporating with the Surea's name meaning. But when stand alone as the san-daichi as a whole, represent the national religion of Surea.
