Introduction to Northeastern Black Bees: Northeastern Black Bees were a group of 18 Russian Far Eastern Black Bees that Zou Zhaoyun from Raohe County carried back on horseback from the Russian Far East in 1918. After nearly a hundred years of closed breeding and artificial selection under local closed environmental conditions, an excellent local bee species was formed and named Northeast Black Bee in 1979. Experts have identified that the Northeastern black bee contains the main excellent traits of the world's four famous bee species (Apis mellifera, European black bee, Carnicola bee, and Caucasus bee). It is my country's precious bee gene bank and is known as the "Honeybee" by the Japanese bee industry. It is called "China's most precious treasure".
