Introduction to the cliff stone carvings: The cliff stone carvings take advantage of the special environment of the mountain and take the original "Yachi" inscribed on the cliff of Niutou Mountain by Tian Songyao, the former commander of the 29th Army of the National Revolutionary Army in 1927 as the center point. The mountain carvings include Du Fu's magnificent poem chanting the rivers and mountains of Zizhou and today's Santai calligraphy masterpieces, showing the profound cultural connotation of Santai.
