First, the source: Yuan Zhu Li Weng Yi sentence: "Silkworms sleep for one or two hours to urge them out, and seedlings are still worried about the wind."
In the dog days, there are three very important time nodes, namely, entering, staying in the middle, and going out and staying in the middle, which means entering into the dog days; staying in the middle is the second volt of the dog days, that is, the period from the fourth Geng Day after the summer solstice to the first Geng Day after beginning of autumn. Going out means that the dog days are over and the dog days are over. These three time nodes constitute the whole dog days.
Second, the word "Fufu" originated from the "River Drills Stones" in Huainanzi Falling Training: "The source of the river flows out of Kunlun, and the Chinese side flows three thousand miles, which leads to the accumulation of stones." The meaning of this sentence is that the river flows out of Kunlun Mountain and lurks underground for three thousand miles. Dayu dredges this and rushes out from the accumulated stones. V means to lurk. If you go out, you will no longer hide.
I often listen to the elders' saying, one year goes smoothly. Judging from this sentence, this time node is the most prone to variables, that is, we often talk about the alternation of Yin and Yang. Judging from the climate, it has been many days in beginning of autumn, so that is to tell us what we should avoid when we hand over in summer and autumn, so that we can have a smooth and prosperous year.
Three bogeys for crouching
First, avoid eating raw and cold food: the so-called raw and cold food refers to raw food, that is, cold food that has not been cooked, which is relatively cold food and is called cold food in Chinese medicine. For example, fruits and vegetables, aquatic products, meat and poultry can also refer to drinks such as ice cream and milk tea. According to the ancient book Huangdi Neijing, it is said that "cold is cold, and it hurts Yang and consumes Yin".
Second, don't eat spicy things: in autumn, the main lung is relatively hot and dry. If you eat spicy food, it will easily lead to getting angry, and it will also hurt your lungs. In Difficult Classics, it is said: "Xin walks with qi, and eating more is against qi, so the winner of Xin's place is anxious, and the winner of Xin's place is slow." Eating spicy food is easy to lead to the dispersion of human qi, and at this time we should be the main convergence, and we should not be scattered.
Third, avoid greedy greasy food: After coming out, it happens to be after entering beginning of autumn. People will think that eating more of this kind of food can supplement the human body with sufficient nutrition, so that it will be particularly comfortable throughout the winter, but I don't know that this time is actually not suitable for eating greasy food.
