There may not be an obvious direct connection between Sun Yat Sen and science fiction at first glance. Sun Yat Sen was mainly known for his revolutionary and political contributions. However, in a broader sense, his ideas about a new and modernized China could be seen as somewhat 'futuristic' in the context of his time, which might have some tenuous links to the concept of science fiction that often involves envisioning new social and technological landscapes.
As far as I know, there is no well - known direct association between Sun Yat Sen and science fiction. Sun Yat Sen was focused on real - world political reform and revolution in China. But perhaps we could consider how his forward - thinking ideas, like his plans for modern infrastructure and education in China, were in a way like the kind of forward - looking concepts that are also present in science fiction. Science fiction might have inspired some of the modernization dreams that were part of his vision, or vice versa, his real - world goals could be seen as a kind of 'non - fictional' parallel to the idealized futures in science fiction.
