People have lived in Yoro Valley since 30,000 years ago, and rice cultivation began 2,000 years ago. There was once a time where rain-fed rice terraces, nourished only by rainwater, spread across this land.

People's prayers have accumulated in the depths of this cave, confined over a long period of time.

Millions of calligraphy characters floating in the depths of the cave each have their own voice. 

Those voices overlap and connect, echoing out as a giant chant.

It is the resonance of prayers left behind in this closed space, like a cave mural where time has stopped, the memories of the people who once lived in this land.
