Why is it said that the Wei, Jin, Southern and Northern Dynasties were an era of self-awareness in literature and history

The Wei, Jin, Southern and Northern Dynasties was a very important period in China's history. It was also a period of major changes and breakthroughs in literature, art, philosophy, and other fields. During this period of history, many outstanding writers and philosophers had also deeply explored and pondered the concept of self-awareness in literature and history. The cultural changes in the Wei, Jin, Southern and Northern Dynasties were in many aspects, including literature, art, philosophy, and other fields. In this context, many writers and philosophers began to explore and think about the concept of self-awareness in literature and history. They believed that the consciousness of literature and history referred to people's conscious respect and attention to history and cultural heritage, as well as their understanding and reflection on themselves and the times. During the Wei, Jin, Southern and Northern Dynasties, many writers and ideologists emphasized the pursuit of literature and history in their writing and thinking. For example, in the literary works of the Wei and Jin Dynasties, there were often descriptions and reflections on historical and cultural heritage, such as the "three parts of the world" in the Romance of the Three Kingdoms, and the "big family" in the Dream of the Red Chamber. These works not only reflected the reality of the society at that time, but also expressed the conscious pursuit of literature and history. During the Wei, Jin, Southern and Northern Dynasties, the philosophers also discussed and thought about the consciousness of literature and history. For example, the Zen master Zong Lin of the Northern and Southern Dynasties believed that self-awareness in literature and history was the pursuit of human wisdom and spirit, and the key to achieving liberation and transcendence. Han Yu, a philosopher in the Tang Dynasty, believed that self-awareness in literature and history was a necessary condition for human beings to pursue the truth and progress in civilization, and to realize the sublimation of personality and spiritual freedom. Therefore, the emergence and emphasis of the concept that the Wei, Jin, Southern and Northern Dynasties was an era of self-awareness of literature and history reflected the changes and progress of society and culture at that time, and also marked a major change and breakthrough in the field of Chinese literature and thought.
