What is Xie Shu's position in the history of China's poetry?

"Going to Wangjing Town after Three Mountains in the evening" is regarded as a masterpiece: "Looking at Chang 'an, the river looks at Jingxian County. The sun sets on the towering roof, and the houses in Beijing are not so high and low. The evening sun is scattered into a beautiful scene, and Chengjiang is as quiet as practice. Noisy birdsong covers the spring, and all kinds of flowers cover the countryside in the suburbs. I will stay in the country far from the capital, and I miss the happy party that has stopped. When it's time for Danggui, I'm disappointed and tears fall like snow beads. If you know your hometown, who can change it? "At this time, Xie Tiao's poems, in addition to the" natural flow of thousands of words "(Liu Xizai's" A Brief Introduction to Art "), are naturally woven into the poems, which makes people feel that there is a kind of deep feeling and wonderful reason besides pen and ink (Shen Deqian's" Ancient Poetry Source "), so every article is a swan song. Zhong Rong said in "Poems" that Xie Tiao's poems were "admired by later literati", hoping that they would be popular in the poetry circle at that time and promote the style of writing. Xie Tiao's poems certainly have shortcomings. For example, they often cannot make the whole article perfect; Compared with the beginning of the article, the ending of Xie Tiao's poetics is relatively dull. Therefore, they can only be "intermediate" works in the development of poetry in the prosperous Tang Dynasty. But because of this, they have high research value in the history of literature. Li Bai, a great poet in the Tang Dynasty, sang in "Farewell Secretary" in Xuanzhouzhuang: "The bones of great writers are your brushes. In heaven, I am Xiao Xie who grew up beside you. We have both been lifted to the sky, and you can shine the bright moon for nine days. " This is the most appropriate evaluation of Xie Tiao's poetry. Li Bai pursues a fresh and natural artistic style all his life, such as Xie Tiao's poem, "Clear water produces hibiscus, and it needs natural carving". In addition, the influence of Xie Tiao's poems on Wang Wei and Du Fu, a poet in the prosperous Tang Dynasty, is also obvious. This fully shows that Xie Tiao has made a special contribution in the history of China's poetry development.
