Poetry and New Year's Eve with the First Frost of Solar Terms

With the poem "Shui Ze withers at the beginning of frost and leaves fall at the end of the year", the sunrise direction is the same as Tianjie, the rain is moist and crisp, and the grass looks close, but there is nothing.

The first frost is the eighteenth of the twenty-four solar terms and the last solar term in autumn. Fight with your fingers; The solar calendar is 210; Celebrate every year on Gregorian calendar 10 year1October 23rd-24th. After entering the first solar term in first frost, the scene of late autumn is obvious, and cold air moves southward more and more frequently. The first frost does not mean "frost", but refers to the sudden drop in temperature and the large temperature difference between day and night. On the national average, "first frost" is the season with the largest temperature difference between day and night in a year.

In the first frost season, it's all over. From the morning, the sun went down to the ground, Yin Qi began to condense, and the first frost weather became colder and colder. Because "frost" is a manifestation of cold weather and large temperature difference between day and night, it is named "first frost", which means "sudden drop in temperature and large temperature difference between day and night". The first frost solar terms are characterized by cold weather in the morning and evening, hot weather at noon, large temperature difference between day and night, and obvious autumn dryness. The solar terms in the first frost mainly include the customs of enjoying chrysanthemums, eating persimmons, climbing high and overlooking, and tonic.

The first frost is the last solar term in autumn and the transition from autumn to winter. In the first frost season, everything is finished, everything goes to heaven, the sun goes to the ground, and the yin begins to condense. The cold weather began with the first frost. Yizhoushu Zhou said: "Autumn and March are empty: summer, autumn equinox, first frost." In Lun Heng, Wang Chong of the Eastern Han Dynasty said: "Clouds and fog are also signs of rain, while summer is dew, winter is frost, temperature is rain, cold is snow, and rain and dew are frozen, all from the ground, not from the sky." Whether it is dew or frost, "it all comes from the ground, not from the sky."
