Introduction to Shangcheng Buddhist Temple: Shangcheng Buddhist Temple, also known as Jing'er, means Dragon City Buddhist Temple in Dai language. It is located on Jinshan Mountain, close to the dragon blood tree community, and is an important part of the ancient city of Nayun Dai. According to legend, there is a stone cave in the temple connected to the Longtan in the Nanlei River. Because the dragons in the Longtan often come to the Buddhist temple along this passage to listen to sutras and sermons and receive incense baptism, it is also named "Longmian Temple".
