Introduction to Sisheng Valley: One of the four wonders of Guifeng, passing through the narrow passage of Yixiantian, and walking only a hundred steps, you will reach Sisheng Valley. The four characters "Yuanmo Thunder" are engraved on the vast green cliff on the left. The three characters "Sishenggu" on the stone were inscribed by Wang Siren, a tourist in the Ming Dynasty. Because when you shout loudly, you will hear continuous responses, and the lingering sound is lingering, so it is named.
