Fang Bao, an ancient prose writer in the Qing Dynasty, commented: "There is no limit to what you see, and the literary realm is unattainable. The good reason is that your body is idle, your chest is bare, your touch is exposed, and you are full of consideration. I don't know why. It's just that others can't imitate it, and even if Zi Zhan is conscious again, it can't be so adaptive and fluent. "

It means: nothing special, the artistic conception of words is incomparable to others. I am open-minded, free from distractions, sincere, and full of language and emotion. I don't know what can make (Su Shi) express such feelings. This can't be imitated by others, even if future generations imitate it, it can't be so smooth. Su Shi expresses his magnanimous mind through various artistic techniques, and he can only forget his gains and losses. Only in this way can we write the unattainable literary environment of "Red Wall Poetry".
