Introduction to Chunqiu on Stone: Also known as sandalwood on stone, it is formed by root splitting, the most common process of biological weathering. The growth of sandalwood trees here has split a huge boulder into several pieces along the surface, forming a rare landscape of trees breaking through rocks. With its tenacious vitality, the sandalwood tree takes root in the cracks of the rocks and stands upright on the rocks. It thrives in the cold and hot weather and thrives upward.
