Introduction to Eight Hundred Cave Heaven: "Eight Hundred Cave Heaven" is located halfway up the mountain on the northwest slope of Fuyun Temple. The four characters "Eight Hundred Cave Heaven" are engraved on the stone. After the Wuxu period, he lived in the mountains in the third year of Jiatai, Guihai, Song Dynasty (3386 years), and Min Jingzhong titled it. (Ming Dynasty) Hong Yingming's "The Strange Traces of Immortals and Buddhas in Vernacular" records that Li Zhen, a native of Shu, was named Ziyang Zhenjun. He lived through the Xia, Shang and Zhou dynasties for 800 years, traveling 800 miles a day at every turn, so he was known as Li Babai. When he was alive, he practiced Taoism and refined elixirs in the stone chamber of Hualin Mountain. After the elixirs were completed, they ascended to heaven. Hence the name Eight Hundred Cave Heaven.
