The decorative art of Kai Yuan temples in Fujian, Guangdong and Taiwan is an important part of the architectural culture of southern China. It consists of the elements of traditional Chinese religious beliefs, folk cultural factors and artistic aesthetics. According to field research, there were five Kai Yuan temples in Fujian, Guangdong and Taiwan. However, the Kai Yuan temple in Zhang Zhou was destroyed in the third year of Tongzhi (1864). The site is no longer available for research. The remaining four historical sites are currently well-preserved and still have high impacts in the local area. Especially, the Kai Yuan temple in Quan Zhou is considered as the oldest Buddhist temple with the largest site scale in China, which is also a national cultural relics protection site. Its architectural decoration art has a great influence on the Kai Yuan temple in Tainan, Taiwan.This study takes the architecture of the Kai Yuan temples in Fujian, Guangdong and Taiwan as the research subject. The objectives of the study are to investigate the architectural decorative art and cultural features at the four Kai Yuan temples through literature review, field research, interview, and methodologies of art research such as imaging method, and to compare the decorative designs, skills and techniques and their cultural characteristics, including the art of inlay decoration, sculpture, ochin ceramic, clay sculpture and painting at the four sites. The similarity as well as the influence in the architectural decorative art among the four sites are discussed. This study aims to facilitate preservation and protection of the architectural art and decorative techniques of ancient religious architecture. This study discusses the architectural decorative art of the Kai Yuan temples in Fujian, Guangdong and Taiwan in different aspects, including historical, artistic, technical and heritage perspectives.

However, the issue of cutthroat competition among the artists might negatively affect preservation of the traditional art. Traditional Chinese religious architecture decorative art requires efforts to be protected and preserved now. This study not only helps to broaden the viewpoints to the traditional architectural decoration art, but also provides precious research materials for further study. It might be useful to help to construct a systematical mechanism in developing the cultural architectural decoration art in Fujian, Guangdong and Taiwan in the future, which is certainly of importance for protecting and preserving the ancient architectural decorative art and painting techniques.
