A plague killed the parents of the teenager Hengjing, and he almost died of illness himself. After he recovered from his illness, he bid farewell to his beloved wife and fellow villagers and decided to go out to study in immortals to rid the people of the plague. Heng Jing visited teachers everywhere and famous scholars all over the world. Finally, he found an oldest mountain in the east. There is a miraculous fairy on the mountain. Under the guidance of the crane, Hengjing finally found the mountain and the immortal with magical power. The immortal was moved by his spirit, and finally took in Heng Jing, taught him the sword to subdue the demon, and gave him a sword to subdue the demon. Hengjing forgot to eat, sleep and practice hard, and finally became an extraordinary martial art.
On this day, the immortal called Heng Jing to his side and said, "Tomorrow is the ninth day of September, and the plague god will come out to do evil again. When you learn the skill, you should go back and kill the people. " Xianchang gave Hengjing a pack of dogwood leaves and a cup of chrysanthemum wine, and secretly taught him how to ward off evil spirits and let Hengjing ride a crane home.
Hengjing returned to his hometown. On the morning of the ninth day of September, according to the fairy's instructions, he led the villagers to a nearby mountain and gave everyone a dogwood leaf and a cup of chrysanthemum wine to prepare for subduing the evil spirits. At noon, with several strange calls, Mo Wen rushed out of the Ruhe River, but just as Mo Wen jumped down the mountain, he suddenly smelled the strange fragrance of Cornus officinalis and the alcohol smell of Chrysanthemum, and then stopped abruptly, and his face suddenly changed. At this time, Heng Jing chased him down the mountain with a demon sword in his hand. These rounds were recorded in the sequel book of June+10/October+August, 65438.
Later, people regarded the custom of climbing on the Double Ninth Festival as an activity to avoid disasters. In addition, in the traditional concept of people in the Central Plains, the Double Ninth Festival still means longevity, health and longevity, so the Double Ninth Festival was later established as the festival for the elderly.
