Introduction to Aishan Pavilion: Aishan Pavilion is purely composed of stone pillars, stone beams and stone roof, with a simple style. There is a couplet in front of the pavilion: "Open the skylight and speak cool (bright) words, and there is a big stone flowing in the middle." It refers to two landscapes: one is that there used to be a huge stone in the stream, like a leaping toad, like the "mainstay of Beiyanxian Holy Gate" ". Another place is the stone skylight.
