Introduction to Beiling Songfeng: At the two pointed forks, overlooking the mountainside, the hills and mountains are winding, undulating like dragons and snakes, stretching for six or seven miles. Green pines are all over the mountain, covering the ground and towering into the sky, the sky is filled with green, and the green clouds are confusing. The wind roars, the sea rolls over the river, the clear thunder rumbles, shaking the mountains.
