This paper aims to observe the beginning period of the development of modernism in Taiwan and Hong Kong with "The Modernist Poetry" and "New Tides of Literature and Arts" as the object of the research. There's a big difference between in Taiwan and in Hong Kong to introduced modernism. The editor of "New Tides of Literature and Arts" introduced the western modernism into Hong Kong and wished to face the society. However, when the "Modernist" in Taiwan faced with official literatue policy, it's not avoid the politics to go to pure literature but coordinate with official literatue policy.
