Legend has it that in ancient times, there was a father and son who lived in the mountains and farmed. Father is lying in bed because of dizziness. One day, my son went up the mountain to herd sheep and heard the sound of turtledoves on the tree. He climbed up the tree and caught two small turtledoves. Suddenly, the wind suddenly blew, flying sand and stones covered the sky, trees swayed everywhere, and only Gastrodia elata did not move. The shepherd boy dug some gastrodia elata and cooked it for his father with turtledove when he got home. The next day, my father's dizziness symptoms improved greatly. My son went up the mountain to dig gastrodia elata, but he didn't find the turtledove, so he took pigeons instead. After dinner, dizziness will soon be over.
