High in the rugged mountains of the Ngari prefecture in the Xizang autonomous region, two young custodians have stepped up to protect and preserve the historic Pyangdungkar Caves, famed for their ancient grottoes and delicate frescoes.

Their appointment marks a turning point in efforts to safeguard this "Millennium Art Treasury" following the retirement of two veteran guardians who dedicated more than 30 years patrolling the caves, maintaining the environment, and educating about the site's history.

Now, two young stewards, Ngakwang Tsering and Tsering Migyur, have taken up the mantle after a rigorous selection and training process.

"To guard the Pyangdungkar site is both a privilege and a profound responsibility," Ngakwang Tsering was quoted as saying by local media Xizang TV. Though the work seems routine, he said it is crucial for preserving an age-old tradition.

Tsering Migyur echoed the sentiment: "The senior guardians' steadfast commitment inspires us deeply."

Each dawn, the two young guardians begin their meticulous rounds, examining frescoes and statues, documenting temperature and humidity, clearing debris, and ensuring fire safety. They also serve as interpreters, patiently explaining the site's artistic and historical significance to researchers and tourists.

"Seeing the youth shoulder their responsibilities gives us great reassurance," said former guardian Champa Tsering.
