The real scene is what the author saw with his own eyes, while the virtual scene is what the author imagined with his mind on the basis of the real scene. China's ancient literary theory emphasized the coexistence of reality and falsehood, that is, reality is the foundation and basis of falsehood, and falsehood is the sublimation and detachment of reality. Without either side, the other side will not exist. It can be seen that virtual scenes and real scenes are relative and complementary. For example, there is a saying in Spring that the flowers are fragrant, the eyes are closed, and the trees are covered with peaches, Xinger and pears. It is clearly written about spring flowers, but how to write autumn fruits. Obviously, autumn fruit is associated with the gorgeous variety of spring flowers, which can be inferred from this flower trend. Autumn must be full of fruits. On the other hand, I'm still writing spring flowers. Without flowers in spring, there would be no fruits in autumn. Therefore, "Spring Flower" is a real scene, and autumn is a virtual scene. It can also be said that writing colors, flowers and flowers directly is a positive description, and writing imaginary flowers is a side foil. Another example is Cao Cao's Looking at the Sea, which is the first poem describing scenery in the history of literature. The order and reality of his scenery are worth studying. The author writes the whole image first, that is, sea water and mountain island, and then writes the local details, that is, trees, herbs and waves, which is the concretization and generalization of the whole. If the rippling of the sea is a dynamic landscape, then the towering mountain islands are static, the vegetation is static and the waves are dynamic. This is also in line with the principle of dynamic and static contrast in landscape poetry. Whether it is moving or static, it is the author's sensory perception. Especially what you saw with your own eyes, which is obviously a real scene. But "the trip to the sun and the moon, if unexpected; Star Han is talented, but it will be different if he is separated. Cao Cao, the author, can't stand by the beach all day and look at the sun, moon and stars. The operation of the galaxy. The sun, the moon, the stars and the milky way in his works seem to be the artistic summary seen by the author. In fact, it is another scene that the author thinks of from the majestic momentum of the sea. The word "if" indicates that this is an imaginary scene. The author thinks of the spirit of the sea in dealing with the sun, the moon and the stars, and the cause he wants to do-to unify China, just like the sea, with the mind to deal with all things in the universe, so as to realize his ambition. There is a famous saying in the west that what is bigger than the sea is the sky, and what is bigger than the sky is the human mind. It can be seen that these two sentences are no longer real scenes, but images with strong subjective colors in the author's mind-virtual scenes. On the surface, the author praises the great mind of the sea, which embraces all rivers and the universe. In fact, he is expressing a broad mind and an unprecedented ambition. The sea seen by the author, like the sea in the author's mind, is choppy and cannot be calm for a long time. This landscape poem written by Cao Cao during the election campaign expressed his views and understanding of the universe and life, with distinctive personality.
