Introduction to Sanshi Hall: According to legend, Wu Sangui and Chen Yuanyuan took refuge here. Chen asked for a signature at the Thousand-Hand Guanyin Hall, and the four words "Qingdeng Ancient Buddha" were written on the paper. As expected, the fortune came true, and Chen Yuanyuan became a nun and bid farewell to the mortal world. So Wu Sangui asked his Taoist friends to inscribe a plaque with the title "The First Lot in Southern Yunnan". It is said that the lottery in this temple is very effective.
