Luo Guanzhong, Wu Chengen, Cao Xueqin and Shi Naian are all representatives of ancient Chinese novels, but their works have different styles and characteristics. Luo Guanzhong was the author of Romance of the Three Kingdoms. He used historical events as clues to create a series of vivid characters to show the history of the Three Kingdoms period in the form of a comedy. Wu Chengen was the author of Journey to the West. He used the mythical story as a clue to express the author's yearning for freedom, justice, and truth by describing the growth process of Sun Wukong and other characters. Cao Xueqin was the author of 'Dream of the Red Chamber'. With the growth of Jia Baoyu, Lin Daiyu and other characters as the main line, she reflected the contradiction between the style of feudal society and human nature through the description of the rise and fall of the family, social reality and character. Shi Nai-an was the author of Water Margins. Based on folklore, he described the limitations and violence of peasant uprisings in feudal society by describing the stories of Song Jiang, Lin Chong and other characters. As these works were all classics of Chinese literature, it was difficult to directly compare who was better. These works all have unique literary styles and ideas, and they are irreplaceable cultural heritages under different historical and cultural backgrounds.
