Introduction to the Psychic Aperture: Walking through the Yingxian Bridge, I saw a huge cliff blocking the way. On it are engraved the two eye-catching characters "Yiqiao psychic" and "Buixianlin". The Yanqing Pagoda on the top of the stone cliff stands majestically, like a painting. Walking into the natural stone door of the "Psychic Aperture" under the stone cliff, you will see waterfalls splashing between the stone crevices, cool air and spiritual rain in the sky, which is very interesting.
