The origin of the festival is around August 23 (August 22-24) in the Gregorian calendar, when the sun reaches 150° of the ecliptic, which is the summertime of the twenty-four solar terms. The arrival of summer heat also means that the second half of the Shen month of the dry branch calendar is entered. The Shen month is the first month of autumn, and although autumn has arrived in the sense that it is already here, the heat of summer is still intact. It is a festival that reflects the change in temperature. The word “dizi” means “hiding” and “ending”, and “dizi summer” means the end of the hot summer days. The “Monthly Order of 72 Huangs” says: “At, go also, the summer heat stops here.” “At” is the meaning of the end, indicating that the heat is about to pass, the summer will end on this day, most areas of China gradually drop in temperature. The summer is different from both the summer, summer, and cold, cold season, it is on behalf of the temperature from hot to cold transition season. Weather characteristics Temperature drops from the end of August to the beginning of September, the summer festival is not enough to be described by the beginning of low temperatures alone. It is only one of the phenomena. The reason behind this phenomenon, first of all, should be the sun’s direct point continues to move south, solar radiation weakened; the second is the subtropical high pressure across the retreat to the south, Mongolia cold high pressure began to leap, fist and foot, a small show of strength. Autumn tiger summer dominance of the subtropical high pressure, although the big step south, but by no means easy to give up the dominant, easy to retreat to the sea in the western Pacific. In its control of the southern region, just feel a touch of autumn cool people, often at the end of the summer, again feel the high temperature weather, which is a veritable “autumn tiger”. Customary activities Release river lantern river lantern is also called “lotus lantern”, generally on the base of the lamp or candle, in the middle of the night in the river, lake and sea, let it float. River lanterns are set up to pacify the falling ghosts and other lonely spirits in the water. Xiao Hong “Hulan River” in a passage, is the best footnote to this custom: “July 15 is a ghost festival; dead ghosts, ghosts of injustice, not allowed to be born, stalking in hell is very bitter, want to be born, but can not find the way. This day if a dead ghost holding a river lantern, you will be reborn.” At the time of summer, our folk have the tradition of eating duck and there are many ways to eat, such as duck with ginger, lemon duck, white cut duck, roast duck, lotus leaf duck, duck with walnuts, etc.. Prevent autumn dryness 4 big trick 1, early to bed and early to rise, sleep well ziwu sleep at the summer festival is the alternate period from hot to cool, nature in the yin enhanced, yang weakened, the body’s yang also with the internal collection, “autumn fatigue” also appeared. Sleep not only eliminates fatigue, but also enables the brain and body to get sufficient rest, which is one of the important methods of health and beauty, and should make full use of sleep to nourish the body.

At the same time, the morning and evening is cooler, to pay attention to increase clothing. 3, early autumn sunscreen is also important Do not think that the autumn has arrived, the sun also began to become gentle, sunscreen is no longer a necessity. Although the temperature drops, people feel cooler, but the fact that ultraviolet rays are still as strong as summer, plus people travel frequently in the fall, sunscreen is still a big thing in skin care, not only should continue to use sunscreen, sunscreen multiples should also be the same as the summer, the general value of ordinary creams containing sunscreen does not meet demand. 4, more drink less talk to prevent autumn dryness Chinese medicine believes that autumn corresponds to the human body is the lungs, autumn dryness injury easy to hurt the lungs, at this time should drink more water, do not wait until you are thirsty and then drink. Chinese medicine has a famous saying “form cold drink cold is hurt lungs”, autumn weather has gradually turned cold, but also avoid cold drink. The dry autumn makes the human skin evaporate more than 600 ml of water per day, autumn must be hydrated. Usually, we should drink more than 500 ml of water per day in autumn than in other seasons in order to keep the lungs and respiratory tract properly moistened, but we should pay attention to a small amount of time. In addition, the daily non-stop talking will also hurt the gas, which is most likely to hurt the lung and heart gas, so pay attention to “less talk”. What to eat at the beginning of summer? At the beginning of the summer, which indicates the coming of autumn, the climate is gradually dry, therefore, we should eat more nourishing and moistening food to avoid the harm of dryness, try to take less spicy, more acidic food to strengthen the function of the liver. At the same time, like watermelon, such cold melons and fruits, should be eaten as little as possible or not.
