This study is based on an exploration of the phoenix books published by Sheng-Xian Temple, Ming-Zheng Temple and Sheng-De Temple. These phoenix books are meaningful because there were published in a time when the leaders of the three temples established the religious sect of Ru-Zong-Shen-Jiao. Therefore, it is worth to use these phoenix books to explore the concept of ghosts and gods in Taiwanese society. The existing studies on folk beliefs only distinguish ghost from god, and regard that they are placed in sort of lineage. This study not only explains the lineage of ghosts and gods in Taiwanese folk beliefs, but also argues that the phoenix books construct the concept of Gong-Guo as moral practice to underpin the lineage of ghosts and gods. The concept of Gong-Guo is developed according to the adaptation to modern society. In short, this paper argues that the concept of Gong-Guo distributed by the temples of the Ru-Zong-Shen-Jiao sect can situate all ghosts and gods into the system of pedigree of the folk beliefs in Taiwanese society.
