The origin of the first frost solar terms

One of the 24 solar terms of the first frost, the weather is getting colder and frosty. The first frost usually occurs on the 23rd day of the Gregorian calendar 10 year 10. At this time, the first frost appeared in the Yellow River basin in China, and most areas were busy planting crops such as three wheat. The first frost said it was colder, and dew and frost condensed into frost. 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. Some people also call morning cream "chrysanthemum cream" because chrysanthemums are in full bloom at this time.

Late autumn is a period of high incidence of respiratory diseases. Eating more pears, apples, olives, gingko, onions, mustard greens, radishes and other foods, rubbing the sides of Xiang Ying's nose and practicing the word "hiss" will help us prevent respiratory diseases.

The cold weather, improper local body warmth or increased human metabolism to adapt to the cold stimulus increase the incidence of chronic stomach diseases and "old cold legs". Especially people with a history of digestive tract ulcer should pay special attention to self-maintenance, adhere to the guidance of doctors and avoid taking food and drugs that are irritating to gastrointestinal mucosa.
