Full text translation: The sun shines on Xianglu Peak, creating curls of purple smoke. From a distance, the waterfall looks like a long river hanging in front of the mountain, as if three thousand feet of water are rushing straight down. Could it be that the Milky Way falls from the sky?

The waterfall is like an incense burner that stands tall in the sky, slowly rising up into clouds of white smoke, misty among the green mountains and blue sky, turning into a purple cloud under the rays of the red sun. This not only renders the incense burner peak more beautiful, but also full of romance. The poetic color creates an unusual background for the unusual waterfall. Then the poet turns his attention to the waterfall on the mountain wall. The first four words of "Looking at the waterfall Kagezenchuan" are the title. "At first glance, the waterfall is like a huge white chain hanging high between mountains and rivers. The word "hanging" is very wonderful. It turns movement into stillness, vividly showing the image of the pouring waterfall in "distant viewing" . The first poem says, “What a great creation! "It is this "good fortune" that can "hang" this giant thing up, so the word "hang" also contains the poet's praise of the magical power of nature. The third sentence also expresses the dynamics of the waterfall. "Flying down. "Three thousand feet" is a sweeping stroke, each word is sonorous and powerful. The word "fly" describes the scene of the waterfall gushing out very vividly; "straight down" not only describes the height and steepness of the mountain, but also shows the rapidity of the water flow. However, the poet felt that it was not enough, and then wrote another sentence: "It is suspected that the Milky Way is falling from the sky." It really wants to fall out of the sky, and the "suspect is" is worth savoring. The poet obviously spoke in a daze.
