How to set off the atmosphere in the novel?

Generally speaking, it is lyrical by borrowing scenery. Contrast atmosphere can describe your surroundings to contrast the atmosphere of the scene. For example, "Leng Yue" written in "Wood Carving of Antelope" shows that the mood is a little sad. Others use contrast, such as "the more complete the movie, the sadder it is" in the lyrics, to set off the resentment in my heart. This example is a description of the psychological environment and can be used to set off the atmosphere.
