Yuntai Mountain is a figure of Tai Chi and Eight Diagrams, which is a concentrated reflection of Taoist culture in the form of natural mountains and rivers.
Zhang Jiyu, director of China Taoist Institute, a direct descendant of Zhang Tianshi's 65th generation and vice president of Chinese Taoist Association, wrote an inscription for Yuntai Mountain: "Cangxi Yuntai Mountain under the Twenty-four Rulings of Tianshi". In 1995, Yuan Yougen, a professor from the Fine Arts Department of Shanxi Normal University, came here for an on-the-spot investigation, and was pleasantly surprised to find that the panorama of Yuntai Mountain was surprisingly similar to the "Taiji Yin and Yang Eight Diagrams"! The Daiqing mountain in Yuntai Mountain is fish-shaped, and the place where the "fish head" is located is called "Sheshen Cliff". It is said that Zhang Daoling ordered his disciples Wang Chang and Zhao Sheng to devote themselves to the valley in order to get the Xiantao, so that they could shed their mortal bodies and become immortals. The white misty hollow valley on the mountain side is also fish-shaped, and the "fish eye" is a natural clear spring at the bottom of the valley. The spring water is clear and sweet, warm in winter and cool in summer. The two "fish" are black and white, moving quietly, solid and empty, yin and yang, and their ends intersect, and they are in perfect harmony. There are eight hills around the main mountain, namely Ziyang Mountain, Tonggu Mountain, Boshuya, Wencheng Mountain, Shuang Shan Mountain, Wenbiya Mountain, Beidou Mountain and Volcano, which constitute the Eight Diagrams.
In the early 199s, Yuan Yougen, a professor from Shanxi University, accompanied by Tao Jialing and Luo Guangchun from Cangxi County Cultural Center (also in charge of cultural relics management), visited Yuntai Mountain and drew the above picture.
A large number of historical materials and facts show that Yuntai Mountain in Cangxi is the seventeenth of the twenty-four religions when Zhang Daoling founded Taoism, and its historical position and practical significance for Taoism in China are self-evident.
