　　Dayao has a long history, with walnuts cultivated here for over two thousand years.

　　 　　Also known as "hetao" or "longevity fruit," walnuts belong to the Juglandaceae family and are deciduous trees. The walnut tree is valuable in its entirety, and its nuts are rich in protein, lecithin, riboflavin, carotene, linoleic acid glycerides, linolenic acid, amino acids, phosphorus, magnesium, iron, manganese, and other essential minerals and trace elements needed by the human body. Long-term consumption helps improve cognitive function, beautify the skin, warm the lungs, nourish the kidneys, prevent cancer, and serves as an ideal natural health food. A 200,000-mu walnut base has now been developed, producing 4,000 tons of dried walnut kernels annually. Through historical changes, many historical sites and cultural landscapes have been created; the trials of time have formed numerous beautiful natural vistas. From December 6 to 11 in the lunar calendar of the 11th year of the Chongzhen reign (1638 AD), the great Ming Dynasty traveler Xu Xiake entered Dayao from Xinhua in Yuanmou County and recorded along the way many historical relics and natural landscapes.
