Chinese culture, with its long history, is a valuable asset shared by compatriots on both sides of the Taiwan Strait and an important bond that maintains the national sentiments of compatriots on both sides of the Taiwan Strait, and proposes that compatriots on both sides of the Taiwan Strait should work together to inherit and carry forward the outstanding traditions of Chinese culture, carry out various forms of cultural exchanges, and form the spiritual force for the great rejuvenation of the Chinese nation. The Confucian doctrine founded by Confucius, which centers on the culture of "harmony", is an outstanding traditional culture of the Chinese nation. Therefore, in-depth studies on the inheritance and development of Confucian culture on both sides of the Taiwan Strait should be conducted to use the power of Confucianism to unite compatriots on both sides of the Taiwan Strait, to innovate and develop cross-strait culture, and to enhance cultural consensus. Taiwan's culture is also very inclusive, while developing its own religious culture, Christianity is prevalent in Taiwan, which is also related to its educational philosophy. This thesis aims to analyze the religion, Confucian culture and educational philosophy in Taiwan.
