In the first frost season, frost is so beautiful.

The first frost is the season with the largest temperature difference between day and night in a year. 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 first frost does not mean that you will be "first frost" when you enter this solar term. In fact, "frost" didn't fall from the sky. Frost is the condensation of water vapor on the ground when it meets cold air due to the change of temperature difference. The solar term "first frost" and "first frost" have nothing to do, they are not the same concept. "In mid-September, the gas condensed and exposed to frost." The first frost occurs when the sun reaches the longitude of 2 10 degrees on the 23rd of 10 in Gregorian calendar every year. At this time, frost has appeared in the Yellow River Basin of China, and pieces of silver ice crystals are shining in the vast fields. At this time, the leaves turned yellow and colorful.
