Legend has it that a poor farmer in named Wei Anxi County in China maintained an ancient run down temple to the Bodhisattva Quan Yin, the Bodhisattva of compassion. One night, he was visited by the Bodhisattva in a dream, and was told to visit a particular spot for his reward, which he was instructed to share with his entire community. At this spot, Wei found a tiny sapling, which he nurtured until it grew into a great tea plant, from which all the Ti Quan Yin tea now derives.
The interesting part of this legend is that this is an incredibly tea, and the Anxi County is in fact where this special type of tea originated.
