Before the mid-1980s, Yu Jian's poems were not experimental, and plateau poems with Yunnan plateau as the background did not receive much attention. In the mid-1980s, especially after the 1990s, his oral writing with daily life as the theme made remarkable achievements in his poems, among which "Ah, Archives", a long poem of archival style, is the representative work of Yu Jian's poems. This long poem is regarded as "the most peculiar poem of our time". After it was published in 1994' s newly-founded Everyone, the evaluation has been mixed, and even some critics think it is not a poem at all. Indeed, it is not surprising to draw this conclusion from the traditional rigid aesthetic norms of poetry. Formally, this poem is a parody of the official document style of "archives". The whole poem is divided into nine parts, namely, the archives room, the birth history of the first volume, the growth history of the second volume, the love history of the third volume (adolescence), the text of the third volume (love period), the daily life of the fourth volume, the table of the fifth volume, the end of the fifth volume (there is no text on this page) and the attachment-the making and keeping of documents. Poetry is written in a blunt, cold, standardized and rigorous official document style. In abandoning the lofty, impassioned and mysterious "poetic language" and adopting documentary, daily and daily spoken language, O Archives has reached the extreme pursued by a new generation of poets. Moreover, judging from the creative intention of this poem, The O Archives also reveals a shocking fact: in the era of political integration, the vivid personal life is controlled, directed and suppressed by a piece of archives, which shows the unquestionable cultural-aesthetic significance of this poem.
