Explain the idioms on the calendar.

(1) festivals during the twenty-four solar terms.

The 24 solar terms, namely, beginning of spring, Rain, Surprise, Spring Equinox, Qingming, Grain Rain, Changxia, Xiaoman, Mangzhong, Summer Solstice, Slight Summer, Great Summer, beginning of autumn, Early Summer, Millennium, Autumn Equinox, Cold Dew, Early Frost, beginning of winter, Light Snow, Heavy Snow, Winter Solstice, Slight Cold and Severe Cold, are all based on the sun in the ecliptic.

② Seventy-two symptoms

The weather lasts for five days, 365 days a year (73 days on average). In order to correspond to the 24 solar terms, it is stipulated that three days are one day (gas) and a year is 72 days.

Each climate corresponds to a phenological phenomenon called "waiting". Weather "weather" should include abiotic and biological categories. The former includes "water begins to dry up", "easterly winds thaw", "rainbows begin to appear" and "the ground begins to freeze". The latter includes animals and plants, such as "the swan goose comes", "the tiger begins to make love", "Ping begins to live", "Bitter vegetable show" and "the peach blossom begins to bloom".

The seventy-two changes originated very early and played a certain role in agricultural activities. Although some phenological descriptions are not so accurate and some are unscientific, they still have certain reference value for understanding the climate and its changes in ancient North China. Because the initial unit of phenology at that time was small and the actual climate and region were quite different, it was difficult to be widely used. Now that the phenology of the Yellow River basin has changed, the phenology of other areas is even more different. We must constantly develop phenology and formulate a new natural calendar, otherwise it is impossible to mechanically copy ancient books.

(3) How many dragons control the water

According to the date of the first day of the first month of each year (Chen is a dragon). For example, the fifth day of the first month is called "Five Dragons Governing Water", and the sixth day is called "Six Dragons Governing Water", and so on. It is said that the more dragons, the less rainfall, and the less dragons, the more rainfall. Since ancient times, there has been a folk proverb that "it doesn't rain when there are many dragons".

A few cows are ploughing the land.

The first ugly day of each year (ugly is a cow) is on the first day of the first month, that is, "a few cows plow the field." The more cattle, the better. The more, the better.

Putting Wang Mingqing said that the heavenly stems belong to gold, the earthly branches belong to fire, and Yin Na belongs to earth. Years of virtue are in Geng, and years of virtue are in B. ...

The first circle in the center and outward of the annual orientation map is the annual orientation map of nine planets, and the taboo of "Huang Wu" and "D" in the text description of the above example comes from the application of this annual orientation map of nine planets. The second circle is the twenty-four mountains (see the article "Twenty-four Mountains"). The third and fourth laps are Nian Shen, who travel all over the country with their age. In the previous example, "three evils in the north in a year" refers to the three evils in the north, such as robbing the sea, sitting in evil without promise, and being abandoned.

Therefore, every Children's Day, and noon rush, are "rushing horses"; Yin Ri and Shen, or "Running Monkey" Huang Li, set up this section to tell people not to choose those days that conflict with their genus.

The old goblin who often lives in the four seasons has become the "Yin Qi of the four seasons". It is extremely vicious and can travel in the sky.
