"Shangshu Shundian" records that Yu Shun said: "Poetry and words, songs and eternal words". The emperor was so holy that he made the definition of poetry clear early on. Therefore, Zheng Xuan (127-200 A.D., Kangcheng, Beihai Gaomi, Confucian scholar and master of scripture in the late Eastern Han Dynasty) said in the "Preface to Mao's Poems": "In the heart is the ambition, the speech is the poem". That is to say: the ambition hidden in the heart, if expressed in words, is poetry. Then, the so-called poetry creation is just to record the feelings of the world with words. Therefore, "poets" are people with ambition and feelings. In addition, in the Analects of Confucius, Confucius extended the words of the Book of Songs, Lu Song, and pointed out that "the three hundred poems are full of words, and the thoughts are innocent...... The sermon of the Divine Word enumerated above is like the apocalyptic symbol of the poem.

When people have seven emotions and six desires, they will sense the changes in everything around them, and then sing songs and dances, and express their ambitions, what a natural thing it is. In the ancient era of Ge Tian, the melody of "Xuanniao" was imitated by imitating the name of the bird, and the dance score of "Cloud Gate" in the Yellow Emperor's season will not be groundless. As for Tang Yao's "Tang Dynasty" and Yu Shun's "South Wind", they are all relatively simple expressions. In the successful Xia Yu Dynasty, the "Nine Virtues" that praised Dayu were obviously justified and modest, and when Taikang's morality was lost, "The Song of the Five Sons" came out immediately, sarcastically admonishing him. It can be seen from this that the function of poetry in praise and satire has indeed been around for a long time. After the Shang Dynasty to the Zhou Dynasty, "Ya" and "Song" became popular, and the "Book of Songs", "Four Beginnings" and "Six Meanings" were integrated. Therefore, in the content of the "Book of Songs" at that time, Zixia (one of the "Ten Philosophers of Confucius" of the Jin Kingdom during the Spring and Autumn Period of the Spring and Autumn Period with the surname Bu Ming Shang) examined "always thought it was gorgeous", which thoroughly understood the fundamentals of faithful etiquette; Zigong (one of the "Ten Philosophers of Confucius" in the late Spring and Autumn Period of Duanmu in 520-456 BC) studied "such as pondering and grinding", and realized the truth of excellence. In view of this, Confucius commented that the two of them already had the qualifications to exchange the experience of the Book of Songs. With the moral decline of the Ji and Zhou dynasties, the collection of folk songs gradually withered. In the Spring and Autumn Period, all sacrifices and entertainments and the introduction of the alliance, the guest of honor used to recite the old works of the "Book of Songs" to show each other's status, dignity and ambition and talent. As a result, the state of Chu was full of complaints, and sometimes "Lisao" was sarcastic; Qin Shi Huang scrapped the book and pit Confucianism, and the accompanying "Xian Zhenren" was attached to the chisel.

At the beginning of the Han Dynasty, the fashionable four-character poems, the first to bear the brunt of Wei Meng (228?-156 BC Pengcheng in the Western Han Dynasty), its style of sarcasm inherited the style of the Ji and Zhou periods. Emperor Wu of the Han Dynasty appreciated literature and built Bailiang Terrace, where the monarchs and ministers chanted poems and composed seven sentences. At this time, Yan Zhu (122 BC-122 BC, his real name was Zhuang Zhu and the famous Cifu family of the Western Han Dynasty) and Sima Xiangru were elegant, and their dictionaries were elegant and prosperous, but there were no fixed regulations. During the period of Emperor Cheng of the Han Dynasty (Liu Biao, the 12th emperor of the Western Han Dynasty in 51-7 BC), Liu Xiang (about 77 BC-6 BC, a native of Zhengpei County, a scholar of the Western Han Dynasty, a bibliographer, a writer), was ordered to compile poems, and more than 300 excellent works were selected inside and outside the court, but he never saw five-character poems. Therefore, the works of Li Ling (134-74 BC Zi Shaoqing Longxi Chengji Western Han Dynasty Famous General) and Ban Jieqi (48 BC-2 AD Han Dynasty Emperor Cheng Concubine Western Han Dynasty Female Writer) were suspected of being forgeries. In fact, in the "Xinglu" of "The Book of Songs, Zhaonan", the five-character poems have begun to emerge, and the "Canglang Song" in "Mencius, Lilou" and "Chu Ci, Fisherman" completely belongs to the five-character lyrics. In addition, the stories of the Spring and Autumn Period, the "Song of Xuanyu" of the Jin Kingdom, and the "Ballad of the Evil Path" of Emperor Cheng of the Han Dynasty in modern times can all corroborate the five-character poems, which have a long history. Like the five-word masterpiece "Nineteen Ancient Poems", some say that it is a multiplication work, but one of them, "Ran Ran Lonely Bamboo", is the handwriting of Fu Yi (A.D.?-about 90 years of Wuzhong Fufeng Maoling people of the Eastern Han Dynasty). If you further examine and study its stylistic content, because it is simple and straightforward but not vulgar, the sentences are tactful and good at fake things, and the emotions are sad and melancholy and real and touching, according to which it can be worthy of the crown of five-word poetry. As for Zhang Heng's "Poems of Resentment", it is not only fresh and elegant, but also has an endless aftertaste, and his poems about immortals and their soothing rhythms are not only elegant and chic, but also have a new charm.

In the Jian'an season at the end of the Eastern Han Dynasty, the five-character poems were like the sun in the sky, and the heroes from all walks of life galloped and galloped, enthusiastically driving. Cao Pi and Cao Zhi brothers competed and went hand in hand, while Wang Cang, Xu Gan, Ying Ying, and Liu Zhen followed closely and showed their abilities. Looking at the content of their poems, or pity the wind and cherish the moon, or play in the pond and garden, or describe the grace and glory, or drink and feast, one by one, they are arbitrarily commanding, and they dare to speak generously. Looking at their artistic attainments, the expressions are conveyed one by one, no longer confined to being slender and well-behaved, and the words and sentences are made in a row, but they only seek to be concise and clear...... This is the commonality of Jian'an's literary style.

In the first years of Cao Wei, Taoist metaphysics flourished, and miscellaneous poems of "Qing Talk, Escapism, and Becoming Immortals" were rampant, such as He Yan (A.D.-249 Ziping Shu Nanyang Wanren Three Kingdoms Period Cao Wei Minister Metaphysician) and others, the rhetoric was rash and shallow, and the content was false and untrue. Only Ji Kang is tall and upright, and his style of writing is high, while Ruan's ambition is claustrophobic and profound, and his words are sad and obscure. Another example: Ying Xuan, who is the author of "One Hundred and One Poems" (190-252 A.D., the brother of Ying Xuan, a native of Nantun, Runan), although the words and sentences are treacherous, but the truth flashes, but it is straightforward and thorough, so that the adversity exists, which can be called unique...... The upright and honest style in this should belong to the legacy of Jian'an literature.

Since the transfer to the Jin Dynasty, poets have gradually tended to be rash and elegant, such as Sanzhang (Zhang Zai, Zhang Xie, Zhang Kang's three brothers), Er Pan (Pan Yue, Pan Ni's uncle and nephew), Zuo Si, and Er Lu (Lu Ji, Lu Yun brothers), entrenched in the literary world, roughly shoulder to shoulder. Their poems, words and sentences are keen on extravagance and exaggeration, completely continuing the customs of the beginning, and in terms of ambition and mood, if they are strong and soft, they are far inferior to the style of Jian'an, especially some are reserved like a dual format, deliberately seeking the subtlety of the rhythm of words, and some of them try their best to conform to the trend of the times, so as to show their talents...... This roughly summarizes the cultural atmosphere of the Western Jin Dynasty.

The Eastern Jin Dynasty was partial to the left of the Jiang, and the atmosphere became more and more indulged in Taoist metaphysics, and cultural talents despised and devoted themselves to current affairs and government affairs. Therefore, since Yuan Hong (about 328-about 376 A.D., the character Yanbo, Chen County, Yangxia, the Eastern Jin Dynasty, the metaphysician, the literary historian), Sun Sui (the 314-371 A.D. Zixing Gongzhong, the Eastern Jin Dynasty Xuanyan poet), although there are those who carve gorgeous from time to time, but the content is all clear, so there is no one who is outstanding. Therefore, only Guo Pu (276-324 A.D., a native of Wenxi County, Hedong County, a famous literary scholar, exegete, and feng shui scholar in the two Jin dynasties) "Wandering Immortal Poems" rose from the ground and became famous for a while. In the early Liu and Song dynasties, although the literary style of the two Jin Dynasty continued, the changes had already emerged. Taoist metaphysics is fading day by day, and the love of mountains and rivers is thriving. As a result, the poets tried their best to find a duality battle that filled the whole text, in order to flaunt the standard of literary brilliance, and even did not hesitate to spend a lot of money, just to demand the novelty of a word. Therefore, all the scenes depicted are extremely realistic, and every word is carefully considered, and the extreme scrutiny is repeated, only seeking to be different, and the dream is a blockbuster...... This is exactly the ideal goal that modern poets are striving for.

Throughout the development of poetry, the changes and progress in it can still be obvious, if not at a glance. Summarizing some of the same and different characteristics of these changes, it is not difficult to grasp the characteristics and mainstream direction of cultural trends at each stage. Generally speaking, the elegant and gentle four-character poem should be a sign of the standardization of poetry, while the five-character poem has a peaceful tone, is known for its clarity and gorgeousness, and can be applied to both fiction and reality, so that the literati and scholars are favored and respected. For example, Zhang Heng grasped the elegance of the four-word poem, while Ji Kang absorbed the warmth of the four-word poem; Zhang Hua condensed the clarity of the five-word poem, and Zhang Xie played the gorgeousness of the five-word poem; As for those who are eclectic and can get their spirits, they should belong to Cao Zhi and Wang Cang, and those who are on the long end and can win better than the blue are the first to recommend Zuo Si and Liu Zhen. However, in terms of content and form, although there are certain rules and circles in poetry, the poet's thoughts and feelings vary from person to person. Therefore, among them, there are very few who can achieve all-round and integrated integration. It is precisely like this, once the difficulty of anything is penetrated, it is easy to do, and it is easy to solve, which is "easy to do"; In the same way, if we rashly assume that poetry creation is a simple and easy thing to do, then it will inevitably lead to the dilemma of "knowing that it is easier to do". Moreover, like three-word poems, six-word poems, and miscellaneous poems, the source can also be classified in the middle of the Book of Songs; There are also word splitting poems, which are fundamentally to meet the needs of diagrams; palindromic poems are Taoist demonstrations of the mysterious; The couplet poem is just a continuation of the genre of "Bailiangtai Poems...... In short, articles like this in terms of word count, form, and content, whether complex or simple, light or dark, more or less, but also sentimental words, can be classified into the category of poetry, and will not be repeated.

All in all: hundreds of millions of people are born with aspirations; The ambition is sung and sung, and the songs are written. The poems of the Three Emperors gradually became popular, and they began to work in the "Second South". Heavenly principles and human feelings are precious and natural, and politics, religion and art are still free. The chapter of the world is uninterrupted, and the style of literature will be passed on forever.
