The key points of this thesis research are the architectural characteristics, formation and transformation of the field functions, interaction and connection among the fields in the buildings of Great Matzu Temple and Kai Yuan Temple in Tainan from the Ming-Zheng era to the early phase of Japanese Showa era. This research also brings the long term possible existence of prejudice and misunderstanding or even hypocritical and fictional history into a dialectical analysis. This thesis performs cross validation on the collected data with the various studies on historical information. Besides, by using available research methods, this research expands and brings this data into discussion, practices a cross-domain multiple fields analysis, fulfills the investigation of the close interaction history on these two fields. There are six chapters in this thesis : Chapter 1 provides an introduction.

In chapter 3 and 4, there are discussions on the architectural characteristics, and field functions of the Great Matsu Temple and Kai Yuan Temple. This research chronologically investigates on building name, field spatial functions, change configuration and redesign of building spatial functions.

This research also shows that the Great Matsu Temple Guan Ting has no spatial and ritual functions for Guan Ting. This provides evidence that the main hall of the Great Matsu Temple located at the third entry was originally the second entry. This research also infers possible reason for the main hall to move from the second to the third entry. 2. After investigation on the names of the property built by Zheng Jing located at the present Kai Yuan temple, we have found that the present popular names such as Cheng Tian Fu Xing Tai, the Garden of Zhou Zai Wei, the Old House of the Zheng Family, the Villa of the Zheng Family, the North Garden of the Zheng Family, the Villa of the North Garden, Zhi Che Yuan etc., were added and named by later generation, the building has no direct relation with Zheng Jing. This research investigates the
