1, about the origin of the first frost.

The first frost is the last solar term in autumn, which is the transition from autumn to winter. There is a lot of heat dissipation on the ground in autumn, and the temperature suddenly drops below 0 degrees. Water vapor in the air directly condenses on the ground or plants to form fine ice needles, and some become hexagonal frost flowers, which are white and loose in structure. "Twenty-four solar terms" said that the first frost: in mid-September, the gas was cold and condensed, and the dew became frost. At this time, frost has appeared in the Yellow River Basin of China, and a piece of silver ice crystals is shining in the fields thousands of miles away. At this time, the leaves turned yellow and fell. The ancient book "Twenty-four solar terms" said: "Qi stagnates at the beginning of frost, and Yin begins to coagulate". It can be seen that the "first frost" means that the weather is getting colder and the dew condenses into frost.
