The first one is the scene with hidden feelings. Although there is no emotion, the scene with hidden feelings often appears deep, such as Li Bai's "a farewell to meng haoran on his way to yangzhou": an old friend leaves the Yellow Crane Tower in the west, and the fireworks go down to Yangzhou in March. The lonely sail is far away from the sky, and only the Yangtze River flows in the sky.
The second one is the scene in love. This way of creating artistic conception. Often express one's feelings directly. For example, Chen xiāng's on a Gate-Tower at Youzhou: where, before me, are the ages that have gone?, and where, behind me, are the coming generations?, I think of heaven and earth, without limit, without end and and I am all alone and my tears fall down.
The third kind is a combination of the above two ways, and the lyricism and scenery writing have reached a seamless level. For example, Du Fu's both sides of the yellow river recaptured by the imperial army: the thistle suddenly spreads to the north outside the sword, at first I cannot check the tears from pouring on my coat. However, it depends on what his wife is worried about, and the book is full of joy.
