What is the poem "The Milky Way Falls for Nine Days"?

"The Milky Way has fallen for nine days" comes from "Suspected that the Milky Way has fallen for nine days" in "Looking at Lushan Waterfall", which means that "the water in that waterfall falls from a very high place, as if the Milky Way had fallen from above nine days".

The two waterfalls in Lushan Mountain are two poems by Li Bai, a great poet in Tang Dynasty. One is an ancient poem with five words, and the other is a quatrain with seven words. These two poems are closely related to the word "Wang" in the title. They both depict the scenery of Lushan Waterfall with incense burner peak, and both highlight the waterfall hanging like a bead curtain with the word "hanging", and depict the waterfall vividly with highly exaggerated artistic techniques.
