According to legend, in the Eastern Han Dynasty, there was a plague demon in Ruhe. As soon as it appears, every family will get sick and even die every day. It's terrible that people in this area have been ravaged by plague demons.

There was a young man named Heng Jing. The plague took away his parents and he almost died himself. After Hengjing recovered from her illness, she bid farewell to her beloved wife and fellow villagers, and went out to study in immortals, so as to save the people. After many hardships and dangers, Heng Jing finally found a magical immortal on an ancient mountain, gave him a demon-reducing sword and secretly taught him how to do it. Hengjing forgot to eat and sleep, practiced hard day and night, and finally developed an extraordinary martial arts.

One 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. Now that you have learned your skills, you should go back and kill the people! " . At this time, the immortal gave Hengjing a pack of dogwood leaves and a bottle of chrysanthemum wine, and gave him the secret of exorcism, so that Hengjing could ride a crane home immediately.

Hengjing returned to his hometown. On the morning of September 9, according to the instructions of the immortal, he led the villagers to a nearby mountain and gave everyone a dogwood leaf and a cup of chrysanthemum wine. At noon, the north wind suddenly rises and the sky is dark. With a few piercing howls, the plague demon rushed out of the Ruhe River and rushed to the foot of the mountain. At this time, the god of plague suddenly smelled the strange smell of dogwood and the mellow fragrance of chrysanthemum wine, shivering and afraid to move forward. Passing 18-wheeler, Heng Jing stabbed Mo Wen to death and wiped out the plague after several rounds of fierce fighting. Since then, the custom of climbing mountains on the ninth day of the ninth lunar month has been passed down.

In the traditional concept of China people, the Double Ninth Festival symbolizes longevity, health and longevity, so people call it the Festival for the Elderly. As early as the Spring and Autumn Period and the Warring States Period, Qu Yuan wrote in "Travel Far": "Gather in Chongyang to enter the Emperor's Palace, build a ten-day period, and see the capital of Qing Dynasty". Cao Pi of the Three Kingdoms said in "Nine Days and the Book of Zhong You": "Year to month, and then September 9 suddenly came again. Nine is the number of yang, and the sun and the moon coincide. It is well known and considered suitable for a long time, so it is a feast. "
