Ask for the introduction of Tang poems in the early Tang Dynasty, and write down the background, military affairs, politics and society.

Poetry in the early Tang Dynasty mainly includes the poems of Emperor Taizong, Tang Gaozong and Wu Zetian. Among them, the main representative poets are the four great poets in the early Tang Dynasty, namely, Yang Jiong, Lu, He Luo, and Zhang and other poets. Their creations, their styles and their artistic features are different from those of previous poets. For example, the four masters in the early Tang Dynasty made a very important contribution to the content of Tang poetry. Before the Tang Dynasty, especially during the Qi and Liang Dynasties, the creation of poetry mainly reflected the life of the court, and the authors were mostly literary attendants such as nobles and emperors, with narrow poetic style and narrow life. In the early Tang Dynasty, due to the further expansion of social life, the contents of early Tang poetry reflected a wide range of social life. For example, among the works of four masters in the early Tang Dynasty, there is a poem like "Ode to Goose" written by Luo, which we are familiar with.

"Goose, goose, Xiang Tiange, white hair floating green water, Anthurium playing clear waves."

This poem shows the shape of a goose on the river with children's eyes and nursery rhymes. And this poem is also very vivid, almost in the form of line drawing, such as Goose! Goose! Goose! Xiang Tiange. White hair floating green water, red palm clear waves. "This poem is not described, not rendered. This is a simple way to vividly show the natural scenery.

Yang Jiong, one of the four outstanding figures in the early Tang Dynasty, is represented by Joining the Army. ("The bonfire shines in Xijing, and my heart is uneven. Leaving the palace, the general will assume the command; Surrounding the enemy and attacking the city, the elite cavalry are extremely brave. The snow is dark and the flag is painted, and the wind is ringing. Better be a centurion than a scholar. " -Yang Jiong's "Joining the Army") The theme reflected by joining the army is different from "Singing Goose". Joining the Army shows the high-spirited enthusiasm of intellectuals in the early Tang Dynasty and their ideal of making contributions to the country. This poem is not only the author's ambition, but also the representative of those intellectuals in the early Tang Dynasty.

In addition to these four outstanding poets, there is Zhang's Moonlit Night on the Spring River, which is not only a poem, but also an ancient song. The ancient song "Moonlit Night on a Spring River" that we hear now is mainly composed of this poem. Moonlit Night on the Spring River is also a famous ancient song in China, which represents the perfect combination of ancient poetry and music in China. There are five paintings in this collection of poems, namely "Spring", "River", "Flower", "Moon" and "Night" mentioned in the title. In this poem, the author writes about the moon at night, starting from the rising of the moon and ending at the setting of the moon. The whole poem is transformed into a scene in a few words, which perfectly combines poetry, painting and philosophy, and later generations will evaluate this poem. Among all the Tang poems, Zhang's works are only three, which is not too many, but this poem has established his position in Tang poetry, so it is well-deserved to call this poem "an isolated poem covering the whole Tang Dynasty".

In the early Tang Dynasty, besides the four outstanding poets and Zhang, he was also a famous poet, so his poems had far-reaching artistic conception, and the famous Youzhou Tower was an example. In terms of meter, this poem embodies another artistic conception of Tang poetry, which is different from other poems. It mainly shows the artistic conception of "pitching the past and the present, from entering the future" and from time to time after the author boarded Youzhou Taiwan. Of course, the environment in which Chen Ziang lived was not in harmony with the social environment at that time. Chen Ziang's poems are either generous or deep, which is another style and taste of Tang poetry.
