There is a legend among the Jinuo people: in ancient times, the world was chaotic and vast.
There are no heaven, earth and mountains, no sun, moon and stars, no vegetation and people. It was the first female ancestor, Amo Yaobai, who opened up the world and created all things. But if you forget to make water, everything in the world is lifeless.
Later, the ancestors created water, and suddenly the torrential rain poured, and the floods came overwhelmingly, submerging the earth, and people and animals were not spared.
A Mo Yaobai had hollowed out a section of tree trunk and covered it with cowhide to make a big drum, so that Mo He and Mo Niu could get into the drum and drift with the water.

After the Great Desolation, the big drum stopped at Siji Zuomi. At that time, the brothers and sisters were still young. Later, in order not to make mankind extinct when they grew up, through divine revelation, Mohe and Mo Niu became husband and wife and multiplied the Jinuo and Dai peoples. , Hani and Blang.
Since then, in order to thank the ancestor Amo Yaobai for creating the world and the big drum for saving mankind, he would sing "Big Drum Tune" and dance "Big Drum" every New Year to express his nostalgia. Saitu has also become a sacred totem worship object of the Jino people. The drum god Setura became the patron saint of the village.
