This paper expounds an event in the historical origin of the relationship between Fujian and Taiwan and its influence on the relationship between Fujian and Taiwan.

Fujian-Taiwan culture refers to the regional culture created by people living in Fujian-Taiwan areas, with Fujian dialect as the main carrier. It is not only an important part of China's traditional culture, but also rich in distinctive regional cultural characteristics-marine culture. Fujian and Taiwan traditional architectural culture is an important part of Fujian and Taiwan culture. Fujian traditional architecture followed the wooden frame of China traditional architecture as the main form, and was introduced into Taiwan Province Province after immigrants settled in Taiwan Province. Whether it is a residential building, ancestral hall, guild hall, Confucian Temple, Guandi Temple, Mazu Tempel Temple, etc., it presents unique ethnic and regional architectural and cultural characteristics. At the same time, while absorbing the traditional architectural culture of China and transplanting the traditional architectural features of southern Fujian, the traditional architecture of Taiwan Province Province is also seeking to show the characteristics of the regional architectural culture of Taiwan Province Province. Fujian established the state of Fujian and Yue in the Han Dynasty, with its capital in Dongye (now Yeshan, Fuzhou), which opened the first page of Fujian's civilization history. During the Three Kingdoms period, the establishment of Jian 'an County (now Jian 'ou), the first county in Fujian, marked the large-scale introduction of Chinese culture into Fujian. Since the Jin Dynasty, Han people from the Central Plains have moved into Fujian on a large scale for four times, distributed in the land of "Bamin". By the Southern Song Dynasty, Fujian had changed from an immigrant society to a settled society, and the Han nationality became the main body of Fujian residents. In the meantime, immigrants not only inherited the advanced culture and production technology of the Central Plains, but also suffered the impact and blending of different regional cultures such as the Yellow River Basin, the Yangtze River Basin and the Minjiang River Basin, and gradually formed the "Fujian Studies" in Fujian during the Song and Ming Dynasties, which became the mainstream thought of China's post-feudal society. In the early Ming Dynasty, due to the government's negative coastal defense policy of "banning the sea" and "moving the border", Fujian coastal residents were forced to go to sea to make a living and seek development. At the beginning of the Qing Dynasty, General Shi Lang implemented the policy of "No Cantonese and hipsters, no crossing Taiwan", which made 80% of the immigrants who passed through the Taiwan Province Strait belong to Fujian Minnan Spring and Zhang Ren, and became the main residents of Taiwan Province Province. This migration is actually a repeat of the Han people's entry into Fujian. The Qing government allowed Fujian and Taiwan ports to cross the Straits, which further strengthened the ties between the two sides of the Straits and the sea. The maritime trade between the Straits in Taiwan Province Province was very active, which resulted in the worship of the sea god "Mazu", which was the result of Fujian and Taiwan's marine culture. Fujian Province and Taiwan Province Province are both immigrant societies in history, and their ancestral homes are in Zhongzhou, and the migration process is generally a combination of blood and geography. When immigrants choose their settlement, they mainly build houses in families, and at the same time rely more on the role of religion to live and work in peace and contentment. This is the basis of folk beliefs in Fujian and Taiwan. Religious subjects, believers, ceremonies and dates are basically the same, and they come down in one continuous line. The research on the historical origin of traditional architectural culture in Fujian and Taiwan shows the sense of identity, affinity and cohesion between Fujian and Taiwan. Religious architecture is produced by worshippers' worship of God. It not only plays an important role in religious belief, but also becomes the essence of traditional architecture in Fujian and Taiwan. In the process of inheritance and development of Fujian-Taiwan traditional architecture, seven branches of Fujian traditional architecture with dialect characteristics have gradually formed, namely Minnan architecture, Mindong architecture, Puxian architecture, Northern Fujian architecture, Central Fujian architecture, Western Fujian architecture and Northwest Fujian architecture. In the process of integration with local Gaoshan compatriots, Han immigrants in Taiwan Province Province also presented four architectural types with dialect characteristics: Minnan architecture, Zhangzhou architecture and Quanzhou architecture, Hakka architecture, Fuzhou architecture and Chaozhou architecture. Fujian-Taiwan traditional architecture is closely related to Fujian Minnan architecture and Taiwan Province Minnan architecture. This paper compares the types of traditional buildings in Fujian and Taiwan from the perspective of history and culture. It can be seen that the plane types of traditional buildings in Taiwan Province Province can be found in southern Fujian, almost all of which are transplanted from traditional buildings in Fujian. This historical origin is related to the fact that most of the Han immigrants in Taiwan Province Province came from southern Fujian. Most of the early traditional buildings were built by craftsmen in southern Fujian and building materials in Fujian, and most of the existing traditional buildings were built during this period. Therefore, Taiwan Province Province not only originated from Fujian in religious belief, but also inherited the tradition of Minnan religious architecture in the form, style and construction method of traditional religious architecture. However, the differences in architectural details reflect that nationality and regionality are natural and social and cultural phenomena. Historically, Taiwan Province Province has been under the jurisdiction of Fujian Province for more than 550 years, including the period of co-governance for more than 200 years. As an important part of culture, architecture has become a historical witness of the same origin of Fujian and Taiwan people. Therefore, studying the historical origin of traditional architectural culture in Fujian and Taiwan will enrich and develop the architectural history of China and the local architectural history in Fujian and Taiwan, fill the gap in the study of architectural history in China, help to explore the historical, scientific and artistic value of traditional architecture, and have academic value for the protection and utilization of cultural heritage in Fujian and Taiwan, the collection and research of historical materials and the reference of modern architectural creation.
