Nepal's flag is the only national flag in the world that is not rectangular in shape. The constitution of Nepal contains instructions for a geometric construction of the flag. According to its official description, the red in the flag stands for victory in war or courage, and is also the colour of the rhododendron, the national flower of Nepal. Red also stands for aggression. The flag's blue border signifies peace. The curved moon on the flag is a symbol of the peaceful and calm nature of Nepali, while the sun represents the aggressiveness of Nepali warriors.
