When it comes to the discovery of tea, it goes back to more than two thousand BC. Legend has it that Shennong's poisonous gas gathered after tasting 72 kinds of poisonous weeds and couldn't control himself. While lying under a tree to rest, suddenly a leaf that was blown off by the wind fell into his mouth. It was fragrant and sweet and refreshed. He chewed on the young branches and leaves of the tree, and the poisonous gas disappeared. Those leaves are our tea today.
