Xiao Xie in the poem "the bones of great writers are your brushes, in the School of Heaven, and I am a Lesser Xie growing up by your side" refers to Xie Tiao. Xie Tiao, the word Xuanhui, was a poet in the Southern Dynasties. Later generations called him and Xie Lingyun Daxie and Xiao Xie. It is used here as a metaphor.
"the bones of great writers are your brushes, in the School of Heaven, and I am a Lesser Xie growing up by your side." A Farewell to Secretary Shuyun at the Xietiao Villa in Xuanzhou, written by Li Bai in the Tang Dynasty, means: Mr. Wang's article has a strong character of Jian 'an, and occasionally reveals the comeliness of Xiao Xie's poetic style.
Appreciation
"the bones of great writers are your brushes, in the School of Heaven, and I am a Lesser Xie growing up by your side." The two farewell sentences are written separately for the host and the guest. In the Eastern Han Dynasty, scholars called Dongguan (the government's book collection institution) Penglai Mountain of Taoism, and in the Tang Dynasty, Pengshan Mountain was mostly used. Pengge referred to the secretary province, and Liu Yun was the school bookkeeper of the secretary province, so here "Penglai Articles" was used to refer to Liu Yun's articles. Jian 'an bone refers to the vigorous "Jian 'an character".
The first sentence praises Liu Yun's vigorous writing style, while the second sentence refers to himself as "Xiao Xie" (that is, Xie Tiao), saying that his poems, like Xie Tiao, have the style of fresh hair. Li Bai admired Xie Tiao very much, and compared with Xiao Xie here, he was showing confidence in his talents. These two sentences naturally fit the title of Xie Tiao Building and School Book.
