Introduction to Wanchun Cave: On the east side behind Yunmen Mountain, there is the "Wanchun Cave" comprehensively excavated by Jiyang. The cave is 1.6 meters high and 1.2 meters wide, with a wide chamber and a depth of 5 meters. On the south side of the cave, there is a stone statue of old man Chen Tuan sleeping with a book on his pillow. Above the head of the stone statue of Chen Tuan, there is a poem "Mountain Dwelling Song" inscribed by the hermit Xuemei of the Ming Dynasty: The stone bed in Yesu is like a cave in the sky, and the bamboo hat is scattered to the east of the sea. Deep in the night, when the white clouds are rising while you are sleeping soundly, don’t worry about the dragon coming to sleep on your bed. His poems are bold and bold, and his fonts are strong and powerful.
