When I stayed in Nepal, I had been to many Hindu temples and found pennant-looking decorations made from copper at the gates of the temples. The moon on the left represents the royal house. The sun on the right symbolizes a branch of the Rana family. The below one is the holy jar called Parna Kalash. The flag of Nepal (Nepal Ko Janda) is the only non-rectangular national flag, based upon the two separate pennants. The flag of Nepal is on the right.
