The Jinma-Biji (Golden Horse-Green Rooster) Archway is a traditional piece of architecture.

The emblem of the city of Kunming is composed of a golden horse and a green rooster. It was designed according to a popular legend about Dianchi Lake. 

On the eastern bank of Dianchi Lake stands the Jinma (Golden Horse) Hill; and on the lake's western bank stands the Biji (Green Rooster) Hill. The two hills form a pass of strategic importance in the city. In remote antiquity, a golden horse ran out of the sun while a green rooster flew out of the moon. Wherever the horse and rooster appeared, trees grew luxuriantly and flowers bloomed, signaling prosperity. They eventually settled on the banks of Dianchi Lake and protected the people of Kunming. 

Nearby Jinma Biji Square is the symbol of Kunming, and the best place for leisure and entertainment.
