Luotian Chestnuts
“Silkworms spin silk, bees make honey, trees yield oil, and mountains produce chestnuts” - this is the specialty that the people of Luotian in the Dabie Mountain area of eastern Hubei are proud of, and the pride that has enabled them to prosper. Luotian began artificial cultivation of chestnuts before the Spring and Autumn and Warring States periods. There are many varieties with unique color and flavor, and the production areas are distributed throughout the county, but their products sold externally are all labeled “Luotian Chestnuts”.
The unique quality and reputation of Luotian chestnuts have attracted many foreigners. Professor Loton from Auburn University in the United States traveled a long distance to Luotian for an investigation. After an on-site investigation of Luotian chestnut varieties, he believed that Luotian is a "world gene bank of chestnuts", and actively introduced American businesspeople to come to Luotian, China, to develop a series of chestnut products. Experts from Japan, Canada, Italy, and other countries have visited Luotian more than 20 times for investigations, and were amazed by the quality of its chestnuts. It is said that after importing Luotian chestnuts, Japan processes them into uniquely flavored chestnut foods and calls them "ginseng fruit".
