Located in the northeast of the Wanda Mountains, this area has a forest coverage rate of over 80% and is home to the largest wild Tilia community in Asia, mainly consisting of purple and bran Tilia. Thanks to the cold temperate climate at 47 ° N latitude, a pure and pollution-free environment, and the ecological advantages of the Black Bee National Nature Reserve, Raohe Tilia honey is known for its natural richness and nutritional richness, and is a national geographical indication product in China.
