Introduction to Futon Pine: In the passage from Yuping Tower to Lianhua Channel, under the Eagle Stone. The tree is 3 meters tall, with side branches densely clustered at a height of 2 meters, twisting around, then extending flat and tilting to the north. The needles are clustered on the top, and the crown is spread flat, like a bulrush made of cattail for monks, Taoists to meditate and kneel down. Futon, hence the name.
