司空图在《与李生论诗书》中提出了“全美”概念,而以往的论述中往往将它作为“醇美”的附属概念,没有赋予其独立的诗学品格。通过对《与李生论诗书》的细读,发现司空图从诗的风格、创作方法,布局以及语言的淘炼多层次地阐释了“全美”的内涵。“醇美”的内涵就是“全美”的内容。“全美”就是“醇美”。 Sitongtu put forward the concept of “the whole nation” in The Book of Poems with Li Sheng, but in the past, it often used it as a subsidiary concept of “meimei” without giving it an independent poetic character. Through the careful reading of The Book of Poems on Li Sheng, we find that Sitongtu interprets the connotation of “All America” ​​from the poetic style, the method of creation, the layout and the panning of language. The content of “mellow” is the content of “all America”. “America” ​​is “mellow”.
