There were several reasons why there were so few Chinese science fiction novels with a space background: 1. Cultural tradition: Chinese cultural tradition has a relatively weak understanding of concepts such as the universe and space. Compared to Western countries, the Chinese placed more emphasis on traditional values such as family, society, and politics. Concepts such as space exploration often contradicted these traditional values. 2. The lack of scientific foundation: China's science education is relatively lagging behind, and there is relatively little knowledge and understanding of science and technology. Therefore, the appearance of space settings in science fiction novels required more in-depth scientific explanation and technical support, which was often difficult to be reflected in Chinese novels. 3. Literature tradition: The literary tradition of Chinese novels focuses on the plot, characters, and theme rather than the grand universe setting involved in science fiction. Therefore, in terms of literary creation, Chinese science fiction often needed more in-depth thinking and exploration rather than simply presenting a story with a space background. 4. Market factors: China's science fiction market is relatively small, and there is relatively little demand and recognition for science fiction. Therefore, China needed to face greater competition and market pressure, which also affected the enthusiasm and innovation of its creation. The reason why Chinese science fiction was relatively rare needed to be analyzed and resolved from many aspects such as cultural tradition, scientific foundation, literary tradition, and market factors.
