What was the relationship between the background of the era and the theme of the work?

The background of the era was often closely related to the theme of the work. The theme of a work was often influenced by the background of the era, as well as the author's personal experience, cultural background, values, and other factors. In literary works, the background of the times often plays a very important role. It is the background and social environment of the story, and also the basis of the character's behavior and thinking. The characteristics of an era, cultural concepts, social style, etc. would deeply affect people's lives, thoughts, emotions, and behaviors, thus becoming an important element of the theme and plot of the work. For example, in 'Dream of the Red Chamber', the background was the feudal society of the Qing Dynasty. This background determined the plot, character creation, and theme of the story. In Journey to the West, the setting of the Tang Dynasty became the basis for many plots and characters in the story. At the same time, the theme of the work was often closely related to the background of the era. A specific era would often trigger specific social problems and contradictions. These contradictions and problems became the core elements of the theme and plot of the work. For example, in Water Margins, the uprising of the heroes at Liangshan Lake took place at the end of the Song Dynasty. The background reflected the corruption, injustice and oppression of the society at that time, which became the theme and the core of the plot. The background of the era and the theme of the work are closely related. Together, they form the meaning and extension of the work. When reading literary works, we need to understand the influence of the background of the times, and also need to dig deep into the theme and plot of the works in order to better understand the meaning and value of the works.
