Introduction to the Sixth Exhibition Room: The "Sixth Exhibition Room" of Xi'an Forest of Steles displays a small number of poetry works from the Yuan and Ming dynasties. Most of the content is aphorisms, so it is called the "Aphorism Stele". Among them, Zhao Mengfu's "Poetry Stele on a Tour to Tianguan Mountain", Dong Qichang's "Send a Farewell to Zhang Sheng in Kuaiji at Moling Hotel" and Lin Zexu's "Poem on a Tour to Huashan Mountain" are all very precious stele stones.
