The incense burner refers to the incense burner peak in Lushan Mountain. "In the northwest of Lushan Mountain, its peak is sharp and round, and the smoke clouds gather and disperse, like the shape of Boshan incense burner" (music history "Taiping Universe"). But when it comes to the poet Li Bai's pen, it becomes another scene: an indomitable incense burner, clouds of white smoke rising slowly in Ran Ran, ethereal between the green mountains and the blue sky, and turned into a purple cloud under the irradiation of the red sun. This not only makes the incense burner peak more beautiful, but also romantic, creating an unusual background for the unusual waterfall. Then the poet turned his eyes to the waterfall on the mountain wall. "Before the waterfall hangs over the river", the first four words are the key points; "Hanging in front of the river" is the first image of "looking", and the waterfall is like a huge white practice hanging high between mountains and rivers. The word "hanging" is wonderful. It transforms motion into stillness, vividly showing the image of a waterfall pouring from a distance. Who can hang the giant? "Zhuang Zaifu"! Therefore, the word "hang" also contains the poet's praise for the magical power of nature. The third sentence also describes the dynamics of the waterfall. "Flying three thousands of feet", stroke by stroke, every word is forceful. The word "fly" vividly depicts the scene of the waterfall spewing out; "Straight down" not only describes the steep slope of the mountain, but also indicates the urgency of the water flow. The sky is falling and unstoppable. However, the poet was not satisfied enough, and wrote another sentence, "It is suspected that the Milky Way has set for nine days". He really wants to fall from the sky and surprise his soul. "Doubt is" is worth pondering. The poet clearly said it in a trance, and the readers know that it is not, but they all think that only in this way can it be more vivid and true. The secret lies in the image that has been bred in the poet's previous description. Look! The towering incense burner peak is hidden in the clouds. Looking at the waterfall in the distance is like flying down from the clouds and falling in the sky, which naturally associates with a galaxy falling from the sky. It can be seen that although the metaphor of "doubt is the milky way for nine days" is strange, it does not appear out of thin air in the poem, but naturally emerges from the portrayal of the image. It is exaggerated and natural, novel and true, thus arousing the resonance of the whole article, making the whole image more colorful, magnificent and magnificent, which not only left a deep impression on people, but also gave people room for imagination, showing Li Bai's artistic style of "Wan Li fell, but the trend was still strong at the end".
Wei Qingzhi, a poet in the Song Dynasty, said: "The fifth word of the seven-character poem should ring. ..... the so-called Ringo is committed to the place. " This view seems particularly convincing in this poem. For example, the word "health" not only makes the incense burner peak "alive", but also vaguely shows the scene of smoke rising in Shan Ye. The word "hang" has been mentioned before, and the word "fall" is also wonderful. It vividly depicts the majestic momentum of sudden high altitude and huge flow. It is hard to imagine what this poem would look like if these three words were changed.
Xu Ning, a poet in the middle Tang Dynasty, also wrote a poem "Lushan Waterfall". As the poem says: "Thunder rushes into the river and there is no peace. The ages are like white practice, and the world is broken. " Although the scene is not small, it still gives people a sense of embarrassment, probably because there are waterfalls and waterfalls everywhere. It looks very strong and hard. Although it is a small poem, it still has a strong flavor. Compared with Li Bai's from the inside out, it is real and ethereal, which is a world of difference. No wonder Su Shi said, "The emperor sent the Milky Way to hang down, and there were fallen immortals in ancient times. I don't want to wash my poems with Xu Ning. " Although the poem "Playing Xu Ning Waterfall" is somewhat extreme, its basic tendency is correct, which shows that Su Shi is not only a famous poet, but also an insightful connoisseur.
