The description of the environment of a lonely journey usually has many functions. The following are some of the common ones: Creating an atmosphere: The description of the environment can provide a specific background atmosphere for the story so that the reader can better feel the emotional atmosphere of the story. For example, in the novel One Hundred Years of Solitude, readers could feel the rich tropical atmosphere and the poor and backward atmosphere through the description of the town of Macondo, so as to better understand the life experience of the protagonist Garcia Marquez. 2. Prominent character psychology: The description of the environment can better reveal the inner feelings and psychological state of the character, allowing the reader to better understand the thoughts and feelings of the character. For example, in the novel " Border Town," the author Shen Congwen described the natural environment of the town to bring the readers into the historical and cultural background of the town so as to better understand the emotional and psychological state of the protagonist Cuicui. 3. Driving the story: The description of the environment can be used to promote the development of the story and provide more background information and plot clues for the story. For example, in the novel Journey to the West, Sun Wukong experienced many dangerous environments and difficulties on his way to learn from the scriptures. The description of the environment could provide enough background information and plot clues for these difficulties to better promote the development of the story. 4. Create artistic conception: The description of the environment can create an artistic conception through the description of the scenery to bring more profound feelings and emotional resonance to the readers. For example, in the novel "Dream of the Red Chamber", the author Cao Xueqin brought the readers into a very unique artistic conception by describing the environment and the activities of the characters in the Grand View Garden, so as to better understand the cultural meaning and emotions of the characters in the novel.
