Chongqing - Chongqing's Dazu Rock Carvings are known worldwide, yet many of them are not located in scenic areas. Scattered across villages and mountains, they have been quietly protected by generations of local residents.

Photographer Dai Xiaobing, a professional photographer for nearly 30 years, first came to Dazu more than 15 years ago. At first, he focused on the carvings themselves. Four years ago, however, he began turning his lens toward the people who guard them.

Among them is Zhou Yaode, who has protected a site for more than 30 years without taking a single day off. When asked how long he would continue, he said, "Until the very last moment of my life."

There is also Sister Feng, who lives near a small cave site. In the rain, her bedding gets wet; in winter, the cave is bitterly cold. Still, she remains there.
