Folklore:

Folk tradition: "369 is an auspicious day. When you go out on an auspicious day, you can be safe and do things smoothly."

Ancient people traveled on auspicious days, which originated from divination and auspicious travel in Shang Dynasty.

In the traditional folk auspicious day culture for thousands of years, people have chosen auspicious days since ancient times, and often use "three, six and nine" as their meanings, thinking that "three, six and nine" is an auspicious number. This folk custom comes from the court rule that "in March, 369, the dragon ascended to the hall and hundreds of officials saluted".

The "three, six and nine" auspicious days designated by the ancient emperors must be carefully studied and repeatedly demonstrated by Yi Dao Buddhists before they can be rational and authoritative.

"Don't wash the pulp on the fifteenth day of the first day"

I only know that according to local customs, the fifteenth day of the lunar calendar is about not sewing, not washing clothes and not going out. I wonder if there is any stress.
