Extract and study a poem by Li Bai.

The purple mist is illuminated by sunlight, and the waterfall hangs in front of the mountain.

On the high cliff, it seems to be thousands of feet high, which makes people think that the Milky Way has fallen from heaven to earth.

This is a landscape poem written by Li Bai when he lived in seclusion in Lushan Mountain at about fifty years old. This poem vividly depicts the majestic, peculiar and magnificent scene of Lushan Waterfall, and between the lines reveals the poet's infinite love for the great rivers and mountains of the motherland.

"Incense burner" in Rizhao Incense burner gives birth to purple smoke refers to a mountain peak in Lushan Mountain-Incense burner peak. This peak is in the northwest of Lushan Mountain, with a sharp and round shape, like a censer. Because of the waterfall, water vapor transpiration, in the bright sunshine, Ran Ran seems to have an indomitable incense burner, purple smoke rising. A "Life" not only vividly depicts the scene of smoke rising, but also sets a vigorous background for describing waterfalls, and also renders the atmosphere of describing waterfalls below.

The word "overlooking the waterfall" takes care of the title "overlooking the Lushan waterfall" from the structural grammar. From the perspective, it is also written in the distance. The word "hanging" in "Hanging Thousand Rivers" was written by Visha Xiao Wei, and the waterfall in the distance hangs straight from the cliff to the river in front of it like a huge white practice. Because of the distance and wide field of vision, the picture is so grand and spectacular: the mountain is smoky, the white mountain is hanging high, and the torrent is rushing down the mountain, which constitutes a beautiful and magnificent picture.

The phrase "Flying down three thousands of feet" describes a waterfall at close range. "Flying Stream" shows the waterfall flying down in the air, spewing and pouring. "Straight down" not only describes the steepness of the rock wall, but also describes the rapidity of the water flow. "Three thousands of feet" depicts the towering mountains in an exaggerated way. Even so, the poet still felt that the majestic and strange momentum of the waterfall was not fully displayed, so he once again rendered it as "suspecting that the Milky Way fell for nine days" and said that the waterfall "flew straight down", which made people suspect that the bright Milky Way poured down from nine days. A poem "Doubt" tells the truth of the poet's imagination, which makes people daydream and feel meaningful, and undoubtedly adds some ethereal, fantastic and magical colors to the waterfall.

This poem is very successful in the use of metaphor, exaggeration, imagination and other artistic expressions. The idea is strange and exquisite, and the language is concise and vivid. It is worthy of being a masterpiece handed down by poet Li Bai!
