Introduction to Lingyan Ancient Cave: The place where Zen Master Tieniu sat and passed away. Zen Master Tieniu is a member of the Yang family temple in Maliantan, Sizu Township, Zhang County. He became a monk at the age of 14 and traveled around at the age of 16. He is the founder of the first Guiqingshan temple. According to legend, in order to build Guiqingshan Temple, he traveled around and asked for help. In order to gain the support of King Su of the Ming Dynasty, he sat in meditation in front of King Su's Mansion for seven days and seven nights. King Su was finally inspired, donated money, and praised the Zen master for his spirit as an iron ox. This is how "Zen Master Tieniu" got his name.
