Introduction to “Feng Gu”: The relief wall of the small square on the west side of the central horizontal axis - “Feng Gu”, is expressed in the form of a Chinese classical screen and has more cultural characteristics. Focusing on the three Cao's achievements in poetry, here we focus on Cao Cao and select "Peng Li Xing", "Guan Cang Hai", "Gui Sui Shou", Cao Pi's "Yan Ge Xing" and Cao Zhi's "Luo Shen Fu". A poem and a painting, both pictures and text, complement each other.
