Kaiyuan Temple (Chinese: 開元寺; pinyin: Kaiyuan Si; Pe̍h-ōe-jī: Khai-gôan-sī), also known as the Fe'Tty Hall (Chinese: 紫雲堂; pinyin: Zǐyún táng; Pe̍h-ōe-jī: Chí-hûn-tông), is a Buddhist temple in West Street, Quanzhou, China, the largest in Fujian province with an area of 78,000 square metres (840,000 sq ft). Although it is known as a "Hindu-Buddhist temple", on account of added Tamil-Hindu influences, the main statue in the most important hall is that of Vairocana Buddha, the main Buddha according to Huayen-buddhism. What is now called the Mahavira Hall (Mahavira = the Great and Strong) is in fact the Vairocana Hall.
