Ngakwang Tsering and Tsering Migyur — chosen through rigorous selection and systematically trained in cultural preservation — have been appointed as the new guardians of the Piyang and Donggar Grottoes. Stationed full-time at the site, they are responsible for daily maintenance, safety inspections and promotion of its cultural significance. "Becoming a guardian of Pyangdungkar (Piyang and Donggar Grottoes) is both an honor and a deep responsibility," said Ngakwang Tsering.

　　Since taking on his new role, he has cherished the advice of the elder guardians, learning the professional knowledge required for cultural preservation.

　　"The work of guarding the caves may seem ordinary, but it pertains to the continuity of a millennium-old cultural legacy," he said.

　　His partner, Tsering Migyur, is also inspired by the older generation. "The elder guardians rooted themselves in the mountains for over 30 years, devoting their lives to protecting this heritage. Their spirit of perseverance has deeply moved us," said Tsering Migyur.

　　Daily duty

　　Each morning, the two young men begin by carefully inspecting every cave, monitoring the condition of murals and statues, recording changes in humidity and temperature, and identifying signs of erosion or environmental risk.

　　They clear debris, prevent wind and sand damage and check for fire hazards.

　　Beyond preservation, they have embraced the role of heritage docents. Whenever scholars or visitors journey to the remote site, they patiently explain the historical significance, mural motifs and cultural value of the Piyang and Donggar Grottoes, helping more people grasp the rich heritage embedded in the ancient caves.
