There are famous articles such as Wild Goose Gate Taishouxing and Yu Liping Yin. He is the author of Long Valley Collection. Li He was a romantic poet in the mid-Tang Dynasty, and he was also called "Sanli" in Tang Dynasty with Li Bai and Li Shangyin. It is a representative of the transition period from the middle Tang Dynasty to the late Tang Dynasty. Most of his poems lament the untimely birth, feel depressed and express the pursuit of ideals and ambitions; It reflects the situation that the vassal region was divided, the eunuchs were authoritarian and brutally exploited the people. Left behind "dark clouds crush the city and want to destroy it", "chickens crow and the world is white", "If there is love in the sky, the sky will be old" and so on.
Li He's poems are full of imagination, and often convey his feelings with myths and legends, so later generations often call him "a ghost genius" and "Shi Gui", and his poems are called "the words of a ghost fairy". There is a saying that "talents are too white and talents are too long." Li He is another famous romantic poet in the history of China literature after Qu Yuan and Li Bai. Li He has been depressed and sentimental for a long time, and his life style is bitter. In the eighth year of Yuanhe (8 13), he resigned as a gift officer and returned to Changgu due to illness. He died young at the age of 27.
There are many reasons to say that Li He is a "ghost". Li He is a romantic poet, and his poems often involve gods and ghosts, but his feelings are not broad-minded and clear, but mostly sad and depressed. Therefore, Li He can be said to be writing poems to death and seeing the world with ghost eyes. Compared with him, the poet Li Bai is also romantic, and the difference lies in his emotional color. In addition, Li He, Li Bai and Li Shangyin are also called Li San in the Tang Dynasty. All three are surnamed Li and are famous poets in the Tang Dynasty. Li Bai preceded Li He, and Li Shangyin followed him. Li He and these two poets are equal, which in itself is an affirmation and praise for him.
Because of its unique style, Li He's poems are called "long auspicious style" by later generations, which is unique in the poetic world and has great influence. Although Li He died young, he wrote many works. According to records, in the late Tang Dynasty, Li He's poems were compiled into 233 poems, but since the Song Dynasty, there have been 220 poems in four volumes. As far as content and subject matter are concerned, Li He's poems can be divided into four types. First, in order to satirize the present, the middle Tang Dynasty in which he lived has begun to decline, with the separatist regime in the buffer region, corrupt political affairs and poor people. This kind of national and social status quo is mainly what Li He did when he was an official. He saw it in his eyes and wrote it in poetry; Secondly, he was angry and lyrical. He was frustrated all his life, so he was angry and dissatisfied. Li He's poems are both positive and heroic, and negative and gloomy.
Thirdly, immortals and ghosts are the embodiment of his imagination and romanticism. Li He often shows the falsehood of ghosts and gods and the inevitability of birth, illness and death. Writing more ghosts is also one of the reasons why he is not called "Shi Gui"; The fourth is to praise people or things, in fact, to express themselves and reflect reality.
Li He's poems were influenced by Chu Ci, Han Yuefu, Li Bai and Du Fu. On the one hand, Li He wrote more classical poems, especially Yuefu poems, and seldom wrote modern poems. It is said that he has no seven-character verse. Besides, he wrote fewer long poems and more short poems. On the other hand, Li He's poems have peculiar imagination and gorgeous language. The strangeness is reflected in his description of supernatural beings and the special way of personification, while the magnificence is because he can often scrutinize and cast his own language. There are many representative works of Li He, such as daydreaming, Wild Goose Gate, Li Ping's Poems, Thirteen Poems of South Garden, etc.
