2. The "first frost" solar term reflects the climate characteristics of large temperature difference between day and night, obvious autumn dryness and gradually cold weather, which does not mean that it will be "frost" when entering this solar term. In fact, "frost" didn't fall from the sky. The "frost" is the condensation of water vapor on the ground when it meets cold air due to the change of temperature difference. There is no concept of "first frost" in meteorology. Meteorologically, the first frost in autumn is generally called "first frost" or "first frost", and the last frost in spring is called "late frost" or "final frost". The interval from the last frost to the first frost is a frost-free period, and "frost" generally appears in autumn, winter and spring. The solar term "first frost" has nothing to do with "first frost" and is not the same concept.
3. 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 season is the turning point of autumn and winter climate, and it is also the transition of the spirit of the sun from being hidden. The key to health care should pay attention to "keeping out the cold outside and clearing heat inside". There is a folk saying that it is better to make up the first frost in winter. In autumn, the spleen and stomach are the foundation of the day after tomorrow. At this time, tonic is appropriate, especially strengthening the spleen and nourishing the stomach to nourish the day after tomorrow.
