Abstract: As an independent immigration event in the history of Chinese immigration, the surnames of the Central Plains moving to Fujian and Taiwan was firstly discovered by Fujian scholars in the early 1980s during the investigation of Fujian dialect and folklore, which responded to the expectations of Taiwan compatriots returning to the motherland. The following are taken as research objects and included in the research scope of the surnames of the Central Plains from Fujian to Taiwan, i.e.: the history of the surnames, the family memory of the surnames, their descendants, as well as the contemporary identification of family memory on both sides of the Taiwan Straits. On the one hand, it is a summary of the 30-year academic history of the research on the transfer of Central Plains surnames to Fujian and Taiwan. On the other hand, it is also a real topic in the academic and cultural exchanges of young people across the Taiwan Straits, both of which are hands-on academic practices, based on which the research content is designed as a study by experience. The "history, memory and identity", the research objects as a state of existence, corresponds to the initial state, transitional state and actual state of the surnames. The research method chosen is called the ecological history research method. The history of cross-strait relations from the perspective of ecological history is a still-living history jointly created by compatriots on both sides of the straits.
