The epics wrote: “The Ling  kingdoms are the world center and Maya region is the source of Yellow River and the center of the Ling kingdoms.” The Ling kingdoms include three tribes of Zalho, Eluo and Zhuoluo. Before Gesar came to the world, the devils and demons were everywhere. The rulers big and small among clans, tribes and ethnic groups fought each other. So peopleÕs responsibility is to protect their country. Men and women, old and young in Ling kingdoms were all proud of brave. They preferred death in the fierce fighting rather than live merely for the sake of living. In the battles, the enemies were usually good at martial arts and heroes from Ling kingdoms often defeated by their enemies. But in an extremely precarious situation, Gesar always fought courageously and swept away all obstacles.
