Introduction to cliff stone carvings: Among Mi Fu's poetry works, there is a poem "Bodhisattva Man·Naked Ancient", which talks about the misty mist under Yubi Pavilion on Shili Changshan Mountain, with reeds nodding and willow branches flickering, a poetic and picturesque scene. The word "Cage Smoke" is Mi Fu's calligraphy, and it is also a highly concise summary and portrait of the smoke in the water and the beautiful mountains here.
