What is the relationship between emotion and scenery?

Simply put, when you are in a certain emotional stage, such as you are sad, so when you see the scenery of fallen leaves or sunset, you think this scene is the external expression of your mood. (This is not the same as touching the scene. First of all, you can distinguish it from the text. One is that you already have "emotions", and then you only see the scene at the moment ... while the latter is to see the unique scenery and then trigger your own "emotions") to melt into the scene: when painters, artists, etc. create, it is this principle. For example, the paintings created by a painter in an indifferent environment are often very quiet and carefree! For example, Tao Yuanming's poems, under the hedge of picking chrysanthemums, leisurely come out of Nanshan ... This is also the carefree state of mind that he has integrated into his own poems: the common expression techniques in poetry writing and the poems with scenes and scenes make people feel like they are in the scene and feel the same. Poems with mixed scenes, real scenes and empty feelings, and the combination of reality and fiction are "wonderful in fiction and wonderful in fact"; The scenery is limited and the feelings are infinite, and the finite and infinite are unified. Fortunately, it is "near but not floating, far and endless." This can often be done as Mei said: "The scenery that is difficult to write is like now, and there are endless opinions", while "the author has his heart and the viewer knows", and each enjoys the beauty brought by creation and appreciation.
