Vietnam is known as one of the oldest tea regions in the world, with a vast area of ancient tea trees spreading from northeast to northwest. Hà Giang province is located in the northeast part of Vietnam on the border with Yunnan province, China. This region is famous for its wild ancient trees grown here for hundreds and even thousands of years. Unique climate, high altitude, rich soil and high level of humidity create an excellent environment for tea trees to grow, what give this tea a particularly special character and taste. This is a homeland of different minorities like Vietnamese, H'Mông, Tay, Kinh, Nung, Dao and others, who traditionally use tea leaves as a medicine and take care about the tea trees.
