Introduction to the historic site: Behind Xiangdian is an open space more than 100 meters deep and dozens of meters wide. It was a place for open-air sacrifices in the past. There is a corridor in the middle and lush trees on both sides. There is a stone bridge at the end of the corridor, called the Big Stone Bridge, also known as the Shengxian Bridge, which means that after crossing this bridge, you will reach the "fairyland".
