From a tea garden in YaAn, Sichuan, China, this tea is known as a tribute to Emperors! In the year 641, during the Tang Dynasty, when Princess Wencheng married Songtsan Gambo, she brought the tribute of dark tea into ancient Tibet. After that, the tea became a vital drink for Tibetan people.

Since it is produced in YaAn, it is also called YaAn Tibetan Tea. This dark tea is the only tea proven by historical events to have made great contributions to national solidarity, border stability, and national unity!
