Ever since Donald Trump was elected as President of the U.S., fake news has become an important issue in the global world. This paper thus explores the phenomenon of fake news that appeared during the 2018 election in Taiwan. Based on the online ethnography method, this research concludes that false proposition, images mixed with misinformation, and imitating online news media are the three main models of fake news in Taiwan. Through the concept of media convergence, this paper argues for a strong interaction between extreme political community and fake news during the election. One serious problem in Taiwan is that the mainstream news media are not alert to the manufacturing of fake news coming from China media.
