According to legend, "Namco is the daughter of Indra and the wife of Nyainqentanglha". Their statues are: Nyainqentanglha-wearing armor, holding a whip in his right hand, holding a rosary in his left hand and riding a white horse; Namco-riding a dragon, holding the dragon in his right hand and the Buddha mirror in his left hand. Nyainqentanglha Mountain is the most authoritative among the northern gods. It has a vast northern territory and rich treasures.

On a hillside on the north bank of Namco, there lived a praise god named Zagu Evil Face. Zagu has a bad face and lives by hunting.

One day, the solar wind rose from the east, and the sunrise crowned the supreme Nyainqentanglha Mountain with a bright golden crown. Zagu's evil face went hunting with a bow and arrow and a broadsword. In Lu Yu You Yue, a black snake and a white snake are fighting. The white snake is aggressive and its maw is stuck on the black snake's head. When he came back full of prey at night, he saw that the black snake had the upper hand again. The cave-like mouth of the black snake is holding the white snake and swinging from side to side. The white snake is dying, half dead. Zhagu's evil face thought for a moment and said, think of the white snake as a god and the black snake as a demon. So he pulled out his broadsword and cut the black snake into two pieces, saving the white snake's life.

A few days later, Zagu's evil face saw a white bison and a black bison on the way out hunting. The white cow is like a high snowy mountain, and every attack makes the black cow have only the power to parry. When Zagu's evil face came back at night, the black cow held high the furry oxtail, two dark nasal cavities were filled with smoke, and the red tongue was shining in his mouth. The white cow had been overturned. Zhagu's evil face thought: this white cow may be a god, and that black cow may be a ghost. He shot the black cow with a bow and arrow made of bison ribs.

As soon as Zagu's evil face arrived home, Nyainqentanglha Mountain was deified into a mortal, wearing a white satin dress and a white headscarf, holding a dagger in his left hand and riding a white horse with a whip in his right hand.

Nyainqentanglha Mountain God said to Zagu's evil face, "Friend, you have helped me a lot. If you need anything, I can meet your three requirements. "

Zagu's evil face is unknown, and he said, "I didn't help anyone, and I don't want you to meet my requirements."

Nyainqentanglha explained, "No, my friend, the white snake and the white cow you saved are my two fascinating animals. I want to repay you for saving my life. "
