Introduction to Sanfuyao: "Sanfuyao" is a stacked stone cave. When drilling the hole, you have to drill it over and over again. It is named after bending down three times in a row. The ancients called it "Jieguan Pavilion". In ancient times, when people went to the mountain to worship, civil servants would get off their sedan chairs and military officers would dismount their horses here. Regardless of whether they were high or low, they would bow three times and pass by. It can be said that "the officials and the people are the most equal here."
