It embodies the country's sobriquet: Land of the Southern Phoenix.
The flag is a combination of two different flag, the Eastern Region's flag and the Western Region's flag, the combination symbolises the reunified state after the Second Reunification War. The top left corner symbolises the traditional East and the country's origin, while the the bottom right corner symbolises the fast growing West and the region's 10 provinces.
