As soon as the sun came out, the dew on the vegetables in Long song Garden dried up. Warm spring brings benefits to everything and makes everything full of vitality, but we often worry about the arrival of autumn, because when it comes to autumn, flowers and plants wither and everything loses its vitality; All rivers flow eastward into the sea. When will they come back? It's no use crying and regretting when you are old if you don't study hard in your teens. "Seven Steps Poetry" is cooked with beans in order to filter out the residue of beans and leave the bean juice as soup; The beanstalk burns at the bottom of the pot, and the beans cry in the pot; Beans and beanstalks originally grew on the same root. How can beanstalk torture beans in such a hurry? The bright moon "Beyond the Great Wall" is the bright moon that frontier soldiers looked up to in Qin and Han Dynasties, and this pass was guarded by frontier soldiers in Qin and Han Dynasties. After a long journey, the soldiers stationed on the border have not returned to their hometown. As long as there is a general like Li Guang guarding the border, we won't let the Hu people's cavalry cross Yinshan to invade the south. This poem is selected from Volume 30 of Yuefu Poetry, which belongs to a genus, and the lyrics are flat. "Yuefu Solving Problems" said that this ancient poem "didn't last long. When you work hard, you will be happy. If you don't get to the boss, you will be sad. " It is obviously a misinterpretation to understand "hard work" as "hard work for pleasure".

From the overall concept, this poem mainly refers to the rapid change of seasons, and the time is gone forever, so people are advised to cherish their youth and strive to make a difference. Its emotional tone is positive. Yuefu Poetry is a collection of Yuefu poems compiled by Guo Maoqian in Song Dynasty, with a total volume of 100 12. From the Han and Wei Dynasties to the Five Dynasties, there were more than ten kinds of pre-Qin ballads. In addition to the music of the feudal court, it also preserved a large number of folk music lyrics and new Yuefu poems created by literati. All kinds of books have a general sequence, each song has a solution, and there are textual researches on the origins of various lyrics. This is a song about life. Singing life begins with the sunflower in the garden, which is called "making things interesting" in writing, that is, "saying something else first causes the words to be sung". In the spring morning, the sunflower in the garden is slim and graceful, with dew rolling on the green leaves, shining in the early morning sun, like a teenager full of youthful vitality. The poet extended from the vigorous growth of sunflowers in the garden and wrote about the whole nature. Because of the sunshine and rain in spring, everything shines with the brilliance of life, and everywhere is full of vitality and prosperity. These four sentences, literally, are a tribute to spring. In fact, it is to compare things with people, and it is a hymn to the most precious thing in life-youth. Life is full of youthful vitality, just like spring is beautiful all year round. In this way, there is a metaphorical meaning in writing, that is, the so-called "Xing and Bi". According to Shi Shuo Xin Yu, Cao Zhi's brother Cao Pi wanted to persecute Cao Zhi after he proclaimed himself emperor, so he ordered Cao Zhi to write a poem in just seven steps. As a result, Cao Zhi sang this seven-step poem. The poet used the metaphor of fried beans to accuse Cao Pi of cruel persecution of himself and other brothers. The first two sentences, "Boil beans and burn beans, and beans cry in the kettle", describe the sharp contradiction between "beans" and "beans" and the cruel persecution of beans by beans. The last two sentences are "born from the same root, why speculate with each other!" Make the finishing point and prompt the theme of the poem. The word "the same root" is a pun. On the surface, it means that "glutinous rice" and "beans" grow on the same root. Actually, they were born to the same parents as xelloss, and asked xelloss why he was so anxious about his younger brother and sister. The metaphor of this poem is very apt, simple and vivid. Although it is still difficult to determine whether this poem itself is really written by Cao Zhi, it reflects the internal contradictions of the Cao Wei ruling group and is indeed a good poem. This is a famous frontier fortress poem, which shows the poet's hope to be a good general, calm the frontier fortress war as soon as possible and let the people live a stable life.

"The Moon of Qin Dynasty was broken in Han Dynasty" cannot be understood as the Moon of Qin Dynasty was broken in Han Dynasty. Here, Qin, Han, Guan and Yue are used alternately, which is called intertextuality in rhetoric, meaning bright moon in Qin and Han dynasties and Guan in Qin and Han dynasties. The poet hinted that the war here has never stopped since Qin and Han dynasties, highlighting the long time. The second sentence "The Long March has not returned" and "Wan Li" mean that the frontier fortress and the mainland are far from Wan Li. Although it is empty, it highlights the vastness of space. The Return of Man reminds people of the disaster brought by the war and expresses the poet's grief and indignation. How can we get rid of people's difficulties? The poet pinned his hopes on a brilliant general. "But make Longcheng fly, and don't teach Huma to cross the Yinshan Mountain." As long as Li Guang, the flying general guarding Liuzhou, is still alive, he won't let the Hu people's cavalry cross the Yinshan Mountain. "Dragon City Flying General Army" refers to Li Guang, a famous soldier who was guarding Lulong City by Emperor Wu of the Han Dynasty. He was brave and good at fighting, and defeated Xiongnu many times. "Don't teach" is not allowed, and the word "teach" is pronounced flat; "Huma" here refers to the cavalry invaded by foreign countries. "crossing Yinshan", crossing Yinshan. Yinshan Mountain is a big mountain range in the east-west direction in the north, and it is the natural barrier of the northern border defense in Han Dynasty. The last two sentences are written implicitly and skillfully, which makes people draw the necessary conclusions by comparing the past. This poem is called the masterpiece of the Tang Dynasty. Tragic but not sad, generous but not shallow, Wang's poem "Out of the Fortress" is two, and this poem is the first.
