The meaning of the cover is the yellow calendar.

China has been a big agricultural country since ancient times. Under the breeding of farming civilization, the concept of "settling in the ground" has left a deep imprint on people's minds. People often pursue their homes and don't move away easily, so building a house has become a major event for every household. On this matter, there is a saying in Peng Zubai's "China Ancient Lucky Choice" that "the owner will open at noon".

"If the house is not built in the afternoon, the owners will be more open." This sentence means that you don't build a roof on this day, that is, if you build a roof on this day, you will sell your house because of lack of money. The ancients thought that every afternoon was a fire, and Vulcan was on duty, so it was forbidden to repair and cover the stove, otherwise it would cause a fire. This is also the image of the ancients "not fighting with heaven, not fighting with heaven".

What does noon mean?

In ancient China, the chronology of the main branches and branches recorded the year, month and day with heavenly stems and earthly branches as the sixty flowers. Noon is one of the twelve earthly branches, and noon is the day when earthly branches are noon. For five days, it appears every 12 days. Of course, the weather is different, that is, Wu Geng, Renwu, Wu Jia, Bingwu and Wuwu. They take turns to be on duty. One day every 60 days is the same in heavenly stems and earthly branches, so there are five or six same noondays every year.

Afternoon is the fire on the five elements, but after cooperating with Tiangan, the five elements in Yin Na are different every afternoon. For example, the five elements in Yin Na, Wu Geng are roadside soil, the five elements in Yin Na in Renwu are willow trees, the five elements in Yin Na, Wu Jia are gold placer, the five elements in Yin Na in Bingwu are Tianhe, and the five elements in Yin Na in Wuwu are fire in the sky, so the characteristics of good luck and bad luck are also different.

The judgment of good or ill luck in the afternoon is based on the balance of the five elements and one's own needs, combined with heavenly stems and earthly branches in the year, month, day and time and heavenly stems and earthly branches in the Universiade and the Palace of Life. If noon is what you need, then it is fierce for you to rush to noon, and it is auspicious when you are born or prosperous; On the contrary, noon itself is not needed, so it is auspicious to rush at noon, and it is fierce when you are alive or prosperous.
