The first sentence is the same as the second sentence, both of which begin with "advise you" and the word "pity" appears twice, which is the reason for the repetition of the two sentences. However, the first sentence says "no regrets" and the second sentence says "no regrets". The meanings of "Mo" and "Xu" are just the opposite, forming repeated changes. These two sentences are very poetic. "Golden robe" is a gorgeous and precious thing, but it "advises you not to cherish it". It can be seen that there is something far more precious than it. This is the "youth" that "advises you to cherish". As for the reason, the poem doesn't say it directly. It goes without saying: "An inch of time and an inch of gold can't buy an inch of time", which is as expensive as gold. "Spin a thousand pieces of silver and come back!" ; However, youth is only once for anyone, and once it is gone, it will never come back. However, the world is puzzled by this, and there are many people who love money like life and waste their time. Over and over again, "Advise the King" pays tribute to the way of hospitality in a conversational tone, with a strong song flavor and touching charm. Two sentences, one negative and one positive, deny the former and affirm the latter, which seem to be divided and combined, forming the first repetition and chanting in the poem, and its melody rhythm is slow. ? Three or four sentences constitute the second repetition and chanting. Poetically similar to a sentence or two, or? The meaning of "don't lose a good time" is not only the repetition between sentences, but also the great circuitous repetition between the upper and lower parts. However, the expressions of the two couplets are different. The first couplet directly expresses the mind, which is the law; The second couplet is figurative and figurative. So repetition still changes. Three and four are not arranged in the same order as one and two, but they are symmetrical in meaning. What if the first sentence says "flowers" and the second sentence says "no flowers"? How to say "Xu" in the previous sentence and "Mo" in the next sentence, there are also pros and cons. The meanings of the two sentences are closely related: "flowers must be folded straight" means "cheer for me through the end of spring" from the front, and "not waiting for flowers to empty branches" means "cheer for me through the end of spring" from the back. They seem to be the same, both of which are the continuation of repeated "advising the monarch", but the intonation rhythm changes from slow to warm. The phrase "can be folded-straight must be folded" has a short rhythm and great strength, and "straight must" is more emphasized than the previous "must". This is a bold song about youth and love. The enthusiasm here is unrestrained, not only frank and bold, but also vivid and beautiful. The word "flower" is seen twice, and the word "fold" is actually seen three times; The clouds of "empty ink" and "empty ink" in the first part of the couplet naturally constitute the beauty of palindromes overlapping. The natural and ingenious repetition of this series of words, sentences and connections makes this poem catchy and the language catchy. In addition to formal beauty, the artistic conception of poetry has changed from a slow cycle to a warm turmoil, which also constitutes the internal rhythm of poetry, which makes people feel more thrilling to read. There is a kind of lyrics, as simple as one or two sentences, which can still gain moving charm after being skillfully composed and repeated with beautiful melody; However, The Witch's Clothing is poetic and simple, but not monotonous, with the characteristics of reciprocating changes. As an independent poem, it is swaying, what's more, it was sung by music in the Tang Dynasty. No wonder it is so fascinating and widely sung.
