What is plum blossom?
Plum blossom, also known as "broken plum blossom", refers to the end date of plum rain. Meiyu in Jianghuai area of China usually ends on July 8-12. In some years, the plum blossom period will be delayed, such as 1954 to August 2, and the plum rain period will last for 63 days. After the meiyu, most areas entered the high temperature season in midsummer.
Traditionally, in our country, the judgment of plum entry and plum exit is based on the combination of solar terms and branches. According to the calendar, the first three days after mango planting or the third day after mango planting is plum blossom, and the first untimely day or untimely day after the summer heat is plum blossom.
Plum entering and plum leaving refers to the beginning and end of plum rain period, which is a unique weather phenomenon in the Yangtze River basin and Jiangnan area of China. The determination of the time of entering and leaving plum is based on the combination of solar terms and branches According to the provisions of the calendar, the first day after planting awns or the second day after planting awns is the day when plum blossoms enter plum blossoms, and the first day after summer heat or the second day after summer heat is the day when plum blossoms emerge.
The standard of plum blossom is: it doesn't rain for 5 consecutive days, and the average temperature (minimum temperature plus maximum temperature divided by 2) exceeds 30 degrees, representing plum blossom.
In fact, plum blossom has three criteria: astronomy, climate and weather:
Astronomical standard, that is, the method of combining solar terms and branches in China's ancient calendar, is a traditional calculation method in China, and the plum blossom time published in some modern desk calendars and calendars is calculated according to this standard.
Climate standard is to determine the approximate time of plum blossom in a certain area according to the average value of plum blossom for many years, which has certain reference value for people's life and production.
The weather standard has specific and detailed indicators, and local meteorological departments issue plum time according to these indicators. Therefore, the plum blossom time indicated on the calendar and desk calendar can only be used as a reference, and the public should still take the "plum blossom" time released by the meteorological department as the standard.

How to preserve health when plum blossom falls in bloom?
One said peace of mind.
When the weather is hot in summer, people are easily agitated and tired. In self-maintenance and exercise, we should take care of the heart yang according to the five internal organs and the heart in summer, so as to ensure the vigorous heart function and conform to the principle of "nourishing yang in spring and summer". "Lingshu All Diseases Began" said: "Honest feelings will hurt filth." This is because the emotional activities of the human body are closely related to the internal organs and have certain rules. Different emotional stimuli will hurt different viscera and produce different pathological changes.
Chinese medicine advocates a word "ping", that is, under no circumstances can there be excessive behavior. When you are overjoyed, you will be sad. If you are heartbroken, you will be distracted, unable to concentrate, and even insane. The heart is the master of the five internal organs, and all life activities are the concentrated expression of the functions of the five internal organs, which are dominated by the heart, and there is a saying that the heart shakes the five internal organs. But the damage to the mind will inevitably involve other viscera. Emotionally speaking, happiness is an inner ambition. This kind of "happiness" is to relieve the tense mood, make the mood comfortable, and make the qi and blood calm. Therefore, the focus of summer health care is "peace of mind", and peace of mind is naturally cool.
