There is a vivid legend about the origin of Sanqi. A beautiful and kind fairy came to the world and taught people to plant. One day, the fairy was working in the field when suddenly a fierce big black bear came at her. At this critical moment, a Miao youth named Kaxiang killed the beast with an arrow and saved the fairy.

Kaxiang's family is very poor. His mother has been ill for many years and has no money to treat her. In order to repay Ka Xiang for saving his life, the fairy said to Ka Xiang, "There is an herb on the back hillside with leaves like my long skirt and branches like my belt, which can be used to treat grandma's illness." Kaxiang, as he said, really found this herb. The old mother took the medicine several times and really recovered.

Later, Kaxiang cured many villagers' diseases with this herb. The villagers came to thank them and asked what medicine it was, which was amazing. The fairy smiled and said, "How many leaves and branches does it have?" ? If you count, there are three branches and seven leaves. A clever girl immediately shouted, "Sanqi!" This name has been passed down to this day.
