Zexian Hall, established during the Meiji period, has undergone multiple renovations and now features a traditional three-section courtyard layout. Nestled within a bustling alley and enclosed by surrounding walls, it offers a serene and tranquil atmosphere, effectively isolating it from the external noise. The main hall's entrance is a single door adorned with couplets: the upper reads "Choose goodness and follow it; compassion is fundamental," and the lower states "The virtuous and sages are great; all forms are empty." Above the door hangs a plaque inscribed with "Zexian Hall." Inside, a moderately sized courtyard serves as the central point connecting the side rooms and the main hall, creating a warm and harmonious environment despite the hall's modest size.
Designated as a Level-3 Historic Monument, Zexian Hall is associated with the Xiantian Sect of the Zhaijiao (Vegetarian Religion), which includes the Longhua, Jinchuang, and Xiantian branches in Tainan. The Xiantian Sect, founded during the Kangxi era, emphasizes self-cultivation without monastic ordination. As the number of followers grew, they collectively funded the establishment of Zexian Hall, primarily dedicated to the worship of Guanyin. After Taiwan's restoration, the hall came under the care of ordained Buddhist monks. The entrance couplets encourage individuals to choose virtuous deeds. Currently, the distinctive features of the Xiantian Sect are no longer visible; even the "Old Mother Lamp" and large water jar atop the ridge are absent. Only a few wooden plaques, tables, and inscriptions from the Showa era remain as indicators of its historical furnishings.
