What does the sunset of Pinus densiflora mean in June 5438+February 2022?

"Red pine falls to the sun" is a traditional festival in China, and it is also considered as an unlucky day. I believe that on this day, even the fields will be sold for drying, and burial will not only take orders, but also divorce and business will be profitable. Therefore, this day is regarded as a big day, and the word "big things are not suitable", so don't do important things on this day.
