What ancient poems do Zhao Kuo's armchair strategist story remind you of?

What you get on paper is so shallow that you never know what you have to do. This is Mr. Tao Xingzhi's famous saying, warning people that some things and experiences need our personal experience to master. Zhao Kuo's theory of an armchair strategist is just the opposite of this sentence. Zhao Kuo only learned the art of war from books, but had no actual experience in leading troops, and he was defeated.
