According to research by Wu Chen-tuo, a Taiwanese tea master regarded as a national treasure, way back in the 5th century AD Turkish traders going overland reached Mongolia or the northern borders of China, where they obtained tea in exchange for other goods.
根據台灣國寶級評茶師吳振鐸的研究，土耳其人早在西元五世紀，就經陸路的商隊至蒙古或華北的邊境，以物易茶。
