Why does a daughter who has been married for less than three years go back to her mother's house on the Double Ninth Festival?

There are six odd numbers and six even numbers in twelve months of the year, and even and odd numbers have become a festival. Most important traditional festivals are dominated by odd numbers. They are the first day of the New Year on 1 month 1 day, Shangsi Festival on March 3rd, Dragon Boat Festival on May 5th, Beggar's Day on July 7th, and Double Ninth Festival on September 9th.

The bustling traditional festivals are based on unlucky odd numbers, because the festive appearance of festivals is to complete the strange moon and strange day from evil to good, and a series of festival activities are set up to suppress and overcome evil spirits.

Odd numbers are also considered positive numbers, and when two Yang meet, they are called Chongyang. Nine is the largest number in the number, so this day is also a big day. The sacrificial activities on this day are climbing, enjoying chrysanthemums, drinking and eating crabs. Climbing is the essential meaning, and the latter three are additional activities.

Climbing a mountain is climbing in the wild, that is, avoiding, leaving the environment of daily life and avoiding the capture of evil spirits. According to legend, there will be a plague on this day, and people should leave their homes and go as high as possible to ensure safety.

There is a vivid description in Taoist legends. Taoist Fei Changfang warned his friends to climb mountains on September 9, and they did. When they came back at night, they saw that the pigs and sheep at home were all dead. This story vividly tells the evil of September 9.

Another ceremony on this day is to put Evodia rutaecarpa on the head. Cornus officinalis is a kind of Chinese herbal medicine, which has the same disinfection effect as wormwood and also means camouflage. In "September 9th" by Wang Wei, I was pregnant with my brother in Shandong. "On the day when I watched my brothers climb the mountain, there was one person missing everywhere", which recorded the family's climbing activities. It emphasizes that the whole family should avoid it, and count whether anyone is left behind. Those who are left behind will be taken away by the plague.

It can be seen that the day when Qiqi meets is called a festival, and holding special ceremonies and activities is a positive measure for people to defend their lives. With the progress of the times, people gradually dilute the taboo content of avoiding evil spirits, while retaining the formal meaning, and festivals gradually become simple celebrations.

Therefore, it seems inappropriate to say "Happy Holidays" on this day when evil spirits should be avoided. It's better to say "good health" or "the whole family is safe"
