Name source:

At the end of Tang Dynasty and the beginning of Song Dynasty, there lived a monk named Pei in Anchangyuan, Shengquanyan at the eastern foot of Anxi Sima. He made his own tea and taught it to the villagers, who called it a sacred tree.

The founder of Qingshui also taught his own way of planting and making tea to the villagers. At the foot of Nanyan Mountain, a retired hunting general "Oolong" accidentally invented the shaking fermentation process because he went up the mountain to pick tea for hunting, and the Tiansheng tea made from it was more mellow.

Wang Shirang asked for leave to go back to his hometown to visit relatives and friends, and found this kind of tea at the foot of Nanyan Mountain. After six years in Qianlong, Wang Shirang was called to the capital to pay homage to Fang Bao, assistant minister of the Ritual Department, and brought tea as a gift. Seeing tea in Qianlong looks like Guanyin, and its face is as heavy as iron, hence the name "Tieguanyin".
