In the modern revival of Mohism,Lu Xun affirms the practical and sacrificial spirit of the Mohists,describing it as"the backbone of China",which has become an established consensus.However,in his work Fei Gong,Lu Xun employs fiction and imagination,focusing on minor characters like Gongshu Ban,and com-pletes the plot model of the ideal trio with the premise of"rational man hypothesis".The novel adopts the technique of"criticizing through praise"to gradually manifest the defects of Mohist thought.The rain-soaked Mo Dithus became a symbol created by Lu Xun to represent the fate of all pioneers.
