What does "150 days of cold food and rain, 24 times of Hua Xinfeng" mean?

"Cold food and rain on 105" means that the 105 day after winter is a cold food festival, and it often rains lightly.

"Twenty-four" refers to the Cold Food Festival after Tomb-Sweeping Day, which brings one of the twenty-four Hua Xinfeng in spring.

These two sentences are from two poems by Xu Fu in Song Dynasty.

"One hundred and fifty days" is another name for cold food, which is counted from the winter solstice. "Twenty-four times" is also a wrong statement.

Hua Xinfeng is the wind that blows when flowers bloom. From slight cold to Grain Rain, there are * * * eight solar terms in April every year, one hundred and twenty days, every five days, which is counted as twenty-four, three times a solar term, and every time a certain kind of flower is in full bloom, so there is the saying of "twenty-four Hua Xinfeng".

According to this record, the plum blossom in Hua Xinfeng is the first and the azadirachta flower is the last. After 24 romantic journeys, the long summer begins.

Extended data

Hua Xinfeng not only reflects the natural phenomena of flowering and seasonality, but also can be used to master the farming season and arrange farming. There are many folk proverbs reflecting phenology:

1, children's noodles in spring, milk noodles after winter.

The weather in spring is changeable. Spring is after the cold winter and before the midsummer. At this time, the south is hot and the north is still cold, and the temperature difference between the north and the south is the largest all year round. Therefore, the cold air in the north and the hot air in the south are often prone to conflict, causing fronts and developing into cyclones. When the cyclone comes, it will rain; The tornado passed and the weather cleared up again. There are the most cyclones in spring, and the weather is changeable, like a child's face, crying and laughing.

The cold wind and dark clouds in winter are terrible, just like the stepmother's face. This is because the north wind prevails in winter, and in Fujian Province, it is a semi-stable polar front, so there are many dark clouds and heavy rains on the sea, and the sky scene is very terrible.

2. February is sunny and green, March is sunny and grass is not born.

The 24 solar terms are fixed in the solar calendar, not necessarily in the lunar calendar. Tomb-Sweeping Day is April 5th in the solar calendar, and the beginning of March in the lunar calendar is all the year round. If you encounter a lunar year with a leap month, it is likely to be in the early February of the lunar calendar. Then, February in the lunar calendar is the weather in April in the solar calendar. March is the weather in May of the solar calendar, which is much warmer than February and March in normal years, so February is clear and the fields are green. Qingming March, the earth has not yet rejuvenated.

3, two spring and one winter, it must be warm.

According to Chinese custom, the first day of the first lunar month and beginning of spring are considered as the beginning of spring. Beginning of spring is in the middle of the lunar calendar, half a month before the first day of the first lunar month. This half month is the end of the lunar calendar, or winter. This means "two spring and one winter".

4. Before the earthquake, it thundered and the clouds opened for 48 days.

According to legend, it is a period of thunder at the beginning of the year. In fact, we can't generalize, it depends on various places and years. The farther north, the later the first thunder; The drier the year, the later the first thunder. If that year, the southern air mass came very early and strongly, the first thunder could have happened earlier. Since the southern air mass comes from the north, there will naturally be more opportunities for rain in the future, but it may not be 48 days.

5, Qingming breaks snow, Grain Rain breaks frost.

This is the phenomenon that winter goes and spring comes, and the weather gets warmer. However, the date of ice and snow rupture varies from place to place. The farther north the latitude, the later the ice and snow break. For example, the average frost breaking date in Nanjing is March 18, and in Beijing it is April 13.
