There was a poem called "Ascending the Mountain" that contained the phrase "Green Mountain and Tower Beyond the Mountain". The full text was as follows: The wind is strong, the sky is high, the apes howl, the white birds fly back to the clear sand of the mournful island. Endless trees fall and the endless Yangtze River rolls down. I'm always a guest in autumn, sad for thousands of miles. I've been sick for a hundred years, and I'm alone on the stage. I'm in trouble, bitter resentment, frosty hair, downcast hair, I've just stopped drinking. Beyond the mountains, green hills, towers, towers, West Lake, vinegar fish are just as fragrant. Drunken in the music of Wu, I like to play with you, white-haired, whose old woman? The eldest son is weaving a chicken coop in the east of Hoe Bean Creek. I like children to lie on the stream and peel lotus seeds.
