What are the three kinds of images in the appreciation of ancient poetry?

Images in poetry include characters, scenes and things. Accurately grasping poetic images is an important starting point for understanding the theme of poetry and the focus of poetry appreciation. To accurately grasp the image, we must first know people and discuss the world, and accurately remember the relevant information of the poet, including his life experience, representative works, the characteristics of the times, the author's political views, and the specific creative background. Poetry about objects needs to pay more attention to the poet's life experience. To appreciate the characters in poetry, we should grasp the identity, personality and fate of the characters and think about the thoughts and feelings entrusted by the author.
