The history of Hubei blue brick tea can be traced back to AD 1368. At that time, Ho, a tea-making family in Hubei, first made hat box tea, which was the embryonic form of Hubei blue brick tea. Later, 179 1 established Changshengchuan Brick Tea Factory, which specializes in producing green brick tea. Since then, Hubei blue brick tea has started its glorious history of more than 200 years and played an important role in the Sino-Russian Wanli Tea Ceremony. Since War of Resistance against Japanese Aggression, Hankou has been unable to make tea. 1939, a man surnamed Liu fled to Anhua, Hunan, and began to teach local people to make brick tea. Because there was no mechanical pressing, the pressed brick tea was soft, which formed the later Fuzhen tea. Fuzhuan tea came out in the early Ming Dynasty. In the old days, raw materials from Anhua and southern Shaanxi were transported to Jingyang, Shaanxi (now under the jurisdiction of Xianyang City) to suppress bricks and tiles. Until 1953, China Tea Company Anhua Brick Tea Factory succeeded in trial-producing Fuzhuan tea, and the production of Fuzhuan tea was transferred from Shaanxi to Hunan.
Green brick tea is made from fresh leaves of alpine tea trees in southern and southwestern Hubei, which are fermented for a long time and then autoclaved at high temperature. The soup is red and clear, fragrant, pure, sweet and meaningful. Drinking green brick tea not only produces fluid to quench thirst, but also has unique effects such as relieving boredom, invigorating stomach, reducing fat and slimming, keeping out the cold and refreshing, sterilizing and stopping diarrhea, which are beyond the reach of other teas. Mainly sold to Inner Mongolia, Xinjiang, Tibet, Qinghai and other northwest regions and Mongolia, Georgia, Russia, Britain and other countries.
