The eight-story buckwheat is grown in the valley of the Basu County in the eastern Tibetan Plateau at an altitude of over 3,300 meters. It has been planted for more than 500 years. Due to the long sunshine time, large temperature difference, low rainfall and large evaporation, Basu has large grain, thin skin and white face. It is rich in protein and multivitamins. It is rich in nutrients and can lower blood fat, blood sugar and cholesterol. Pollution-free healthy food.
