The National flag is divided diagonally with a white dragon in the center of the flag.
The national flag is half yellow and half red. The upper yellow half signifies the secular power and authority of the king while the lower saffron-orange symbolizes the practice of religion and the power of Buddhism, manifested in the tradition of Drukpa Kagyu. Bhutan is a religious country with Buddhism as its official religion. Bhutanese people call their country as 'Druk yul' or 'Land of the Thunder Dragon'. Bhutanese believe that thunder is actually the voices of the dragon roaring. Thus the dragon in the center of the flag or 'Druk' has deep association with the country itself.
