"Gesar" is a grand narrative about the sacred deeds of the ancient Tibetan hero Gesar. The epic tells the heroic story of King Gesar who plunged into the lower world to save lives, led the people of Lingguo to subdue demons, suppress the strong and help the weak, settle the three realms, complete the mission on earth, and finally returned to heaven. With the singing and rapping of outstanding artists, the epic has been circulated for thousands of years, mainly in the vast pastoral areas and rural areas of the western plateau of China. The epic fully reflects the experience and knowledge of the Tibetans and other related ethnic groups about all things in nature, and has become a spiritual wealth shared by ordinary people of Tibetans and other ethnic groups. It is still an important basis for the historical memory and cultural identity of Tibetans and other ethnic groups.
