The image of Mozi in Lu Xun's novel Fei Gong is very different from that in the ancient prose Gongshu. In the book, Mozi was a wise, brave and righteous figure. He opposed war and advocated peaceful solutions to problems. He put forward important ideas such as "universal love","non-aggression","respecting the virtuous", etc. He believed that human beings should respect each other and treat each other equally to avoid war and violence to solve problems. Mozi also advocated the use of science and technology and reason to solve problems. He invented practical tools such as the Mohist mechanism to help people solve the problems brought about by war. In contrast, Mozi in the ancient text Gongshu was more mysterious and legendary. He was portrayed as a mysterious figure with extraordinary wisdom and mysterious abilities. In the story, he could predict the future, use magical Mohist spells to solve problems, and even communicate with divine objects. In the ancient prose Gongshu, the image of Mozi was even more mythical and supernatural, far from the human wisdom in reality. Therefore, the image and thoughts of Mozi in Lu Xun's novel Fei Gong were very different from those in the ancient prose Gongshu.
