Determined to learn, Sinchung taught herself the Tibetan alphabet at 14. Scribbling letters into the sand while tending to livestock, she grew proficient over the years.
Reading books about King Gesar became a natural progression, even as she faced skepticism from her community.
"At first, elders appreciated my storytelling, but others mocked me or insisted that such tales were not meant to be sung by a woman," says Sinchung, describing challenges that ranged from societal taboos to outright hostility.
"Some even cursed my family, warning of disastrous consequences," she says.
For a time, the criticism silenced her. Public storytelling stopped, but in solitude, she carried on, practicing Gesar's tales while herding. The process, she says, brought her solace and happiness during those trying years.
Between the ages of 17 and 25, Sinchung dove deeper into the epic. Borrowing books from other storytellers, she expanded her knowledge of the king's journey from his celestial birth and struggles on Earth to his victorious battles against enemies.
During this time, she endured mysterious illnesses that seemed to ebb only when she immersed herself in the poetic verses of King Gesar.
Her marriage at 26, followed by the responsibilities of family life, led to another hiatus. Storytelling took a backseat, especially under her husband's disapproval.
However, WeChat rekindled her passion, providing a new platform to share her art. Singing and rapping Gesar's tales in group chats garnered widespread recognition and won over audiences.
In 2020, Sinchung's family relocated to Sinpori, an ecological resettlement community in Xizang's Gongkar county, as part of a government program to improve the living conditions of high-altitude nomads.
The move to a more community-oriented environment gave her a new platform.
"With my neighbors living close by, it was easy to gather people for storytelling," says Sinchung. The teahouses of Sinpori welcomed her performances, and she eventually established a dedicated King Gesar Storytelling House.
Visitors from near and far listened to her accounts of the heroic king's exploits, bridging ancient glory and contemporary life.
However, Sinchung believes her storytelling alone is not enough to protect this intangible cultural treasure. Embarking on a new mission, she is documenting her knowledge in writing to ensure its preservation for future generations.
With government policies emphasizing the protection and promotion of cultural heritage, she found the encouragement she needed.
"By publishing books, I am ensuring that this invaluable cultural legacy doesn't perish with me," she says. "These stories will serve as an inheritance for future generations, enabling them to connect with and celebrate their identity."
Plans for additional publications are already in motion, ranging from collections of proverbs to compilations of Tibetan riddles.
For Sinchung, storytelling transcends entertainment; it is a living, breathing link to a storied past, and an enduring gift to posterity.
"If I live longer, I hope to contribute more. These stories are not just history, they're a part of us."
