Deep in the rock layers, the rings of time rotate in silence, and underground water quietly seeps through the cracks, absorbing the warmth of the earth and the breath of time. Thousands of years of accumulation and the compression of the earth's crust cause water to surge and warm up in the darkness, eventually becoming hot springs. Just like the dialogue between humans and nature. It carries ancient memories, warms every inch of the skin, and washes away the dust of the soul, like a gift of time, telling the eternity and tranquility of the earth.
