Changes in social background: During the Ming and Qing Dynasties, China's social politics, economy, culture and other aspects had undergone tremendous changes. These changes provided a broad background and material for the development of novels. 2. The demand for literary creation: During the Ming and Qing Dynasties, with the end of the feudal society and the development of the commodity economy, people's demand for literary works also increased. 3. The rise of novel schools: In the Ming and Qing Dynasties, there were many different novel schools, such as classical novels, detective novels, love novels, etc. The rise of these schools also provided different topics and styles for the development of novels. 4. The development of literary criticism: During the Ming and Qing Dynasties, literary criticism gradually took shape, and it carried out in-depth discussions and criticisms on the literary form, theme, and ideas of the novel. These criticisms also provided theoretical support for the development of the novel. To sum up, the development of Chinese novels in the Ming and Qing Dynasties was inseparable from the changes in social background, the needs of literary creation, the rise of novel schools, and the development of literary criticism.
