In the hot summer, how can you stop this snarling "hot devil" without a few bites of "ice"? Eating "ice" in summer is not the patent of modern people, and the ancients especially like to use "ice" to spend the summer.
But this is not an ancient refrigerator. An ancient refrigerator named Bing Jian is recorded in Zhou Li. The bronze ice guide unearthed in the tomb of Zeng Houyi in Hubei Province in 1978 is considered as the earliest "refrigerator".
it's a two-story container with a square outer layer and a round square-mouth jar inside, which can be taken out. Food such as fruits and drinks are put in the jar, and ice can be put between the jar and the outer layer. There is a big lid on it, and a small lid is opened in the middle of the big lid. When taking things, you don't need to open the whole lid. Just open the small lid on the top of the mouth and you can take the food inside. It is also specially equipped with a long-handled spoon for taking food.
in the Ming and Qing dynasties, there were many ice guides made of mahogany or huanghuali wood. The outer layer of the wood was covered with lead or tin. Because of the poor thermal conductivity of lead and tin, the insulation effect was good, and the ice cubes could not be completely melted all day. Covered with a layer of lead or tin, it can not only keep warm, but also prevent the water from eroding the wood when the ice melts.
The ice guide made of wood has richer surface decoration and color, just like a work of art.. There is a drain hole at the bottom of the guide, and the water after melting ice can flow out through the drain hole. There are lifting rings on both sides of the box, which is convenient for carrying. The top cover is provided with double money holes, which is not only a hand-picking, but also a cold air outlet. Putting the ice guide indoors can be used as both a refrigerator and an air conditioner.
There was no electricity in ancient times, and ancient refrigerators could not be cooled by electricity like today's refrigerators. Where did the ancient ice come from?
At the beginning, the ancients used natural ice cubes, that is, in the cold winter, they brought the natural ice cubes back and kept them in the cellar, also known as icehouse. When ice is used in summer, it is taken out of the icehouse. This kind of storage method, with the change of temperature, is definitely a great loss. Therefore, when collecting ice cubes in winter, it is usually three times as much as the amount used.
picking, transporting and storing ice are laborious and costly things, which ordinary people definitely can't enjoy. Only princes and nobles can enjoy them. Ordinary people only collect and transport ice, which was a special occupation in ancient times, called Lingren.
in the Tang dynasty, when people mined a lot of saltpeter for producing gunpowder, they found that saltpeter would absorb a lot of heat when it was dissolved in water, which could cool the water to freezing. Since then, people have learned to make ice, which is no longer limited by seasons.
With the ice-making method, the amount of ice has greatly increased, and ice is no longer limited to princes and nobles. There are also ice cubes on the market, but the price will not be cheap, and people with a little status can enjoy them.
Despite the ice-making method, natural ice cubes are still an important source. In the Qing Dynasty, there were still professionals who took ice cubes from the moat and hid them in the icehouse for use by the royal family and dignitaries in summer.
in the song dynasty, besides cold wine, all kinds of cold drinks gradually increased. There are so many cold drinks in the market that there are more cold drink shops in the night market. "Ice-snow licorice soup", "snow soaked Doo water" and "cold water litchi paste" were all popular cold drinks at that time.
By the Ming and Qing Dynasties, ice storage was no longer just an official act, but also many folk icehouse appeared, and ordinary people also had the opportunity to enjoy a cool summer.
At this time, chilled food has spread all over the streets. In midsummer, there are still many vendors carrying the burden and selling "cold water" along the street, that is, some cold drinks.
Of course, there are always people who can't eat ice, but the wisdom of the people is endless. They will put melons and fruits such as watermelons in baskets, then hang them in wells, soak them in well water, and then pull them up in a few hours, which is also chilling to eat.
there is a law in nature, that is, in spring and summer, the yang is floating outside, and in autumn and winter, it is collected inside. For the earth, floating outside is above the surface. In spring and summer, the temperature on the ground is higher than that on the ground, and it is just the opposite in winter, so the basement, well water and seawater are warm in winter and cool in summer. A well in summer is like a natural refrigerator. The method of freezing with well water was still popular until the refrigerator was not popular decades ago, and now some rural areas still continue to use this kind of free freezing method.
In hot summer, the heat is unbearable. It's no harm to eat a few cold drinks and iced fruits. After all, high fever and heatstroke will kill people.
However, we should also know that the rule in summer is that the yang is floating outside, and the yang in the middle of the spleen and stomach is relatively weak. Eating iced food will bring endless troubles to the spleen and stomach. Maybe some problems will not happen immediately, but will lurk down, and I will settle accounts with you after autumn, even for many years, and finally I will settle accounts with you. It's not that we don't report it. It's not time. Eating ice in summer is still enough.
Besides, we should learn some methods to repair the damage caused by eating ice. For example, "eat radish in winter and ginger in summer" and ginger in summer is to deal with iced food. Therefore, people who love ice should eat more ginger in summer.
Chongqing people and Sichuan people's congresses also want to eat spicy hot pot in summer, which is not only addictive, but also instinctive. Through the warm and pungent dispersion of pepper, the cold and damp gas accumulated in the body can be excreted, so as to ensure the balance of the body.
Therefore, eating ice or spicy food, eating ginger or drinking herbal tea is not an independent judgment. It should be decided according to the individual's physical fitness at that time, and the daily diet should be well balanced. Don't blindly favor one aspect, which will lead to the imbalance of the body.
I recommend a way to eat ginger. People who like ice, or people with spleen and stomach deficiency and cold, can eat it often.
▼ Practice: Wash the tender ginger, dry it, cut it into pieces the size of a 1 yuan coin, put the ginger slices in a container with a lid, and pour in the old herbal medicine until the ginger slices are uncovered. If you don't like eating too sour, you can add a little rock sugar to soak and season. Cover and soak for 7 days before eating.
As the saying goes, "Ginger is still old and spicy", and tender ginger is not so spicy. It is generally recommended to use tender ginger to make vinegar soaked ginger. If it is used to boil ginger soup or ginger jujube paste, it is recommended to use ginger.
Ginger meat is pungent and warm to dispel cold, while ginger skin is pungent, cool and clear of heat. Under normal circumstances, it is recommended not to peel ginger to ease its pungent and scattered nature. If the stomach cold is severe, or it is used for cold syndrome, it is recommended to peel it.
It is recommended to eat ginger soaked in vinegar in the morning, which can be eaten as a snack or as breakfast with millet porridge. In the morning, sun be the spirit to promote hair growth. Jiang Ye is the thing that stimulates hair growth. Eating in the morning is the same as seeking for the same spirit, which is more in line with the laws of the body. At night, the yang should be restrained, and divergent food should be eaten less, so as not to cause problems such as excessive internal heat, insomnia, dryness and heat. Therefore, in general, there are no special circumstances. Don't be jealous of soaking ginger at night, but it is no problem to put some ginger as seasoning when cooking. If you get cold at night, you can eat ginger or drink ginger soup.
Generally speaking, everyone can eat 2-3 slices of ginger soaked in vinegar every day. I usually soak 21 pieces of ginger in a bottle, which is enough for 7 days. When this bottle begins to eat, it begins to soak the next bottle. After the last bottle is finished, the new bottle has just been soaked for 7 days and can be eaten. In this way, two bottles will circulate without interruption.
yes, but the longer the soaking time, the weaker the spicy taste of ginger, and the weaker the divergence effect, while the convergence effect of vinegar increased. If you want to dispel the cold, the effect is not as good as the short soaking time.
When soaking, ginger must be washed and dried, and the container in which it is placed should be clean, and the whole production process should be water-free and oil-free,
otherwise it will go bad easily. If there is no water or oil in the whole process, ginger soaked in vinegar can be preserved for a long time even at room temperature.
Yes, as long as it doesn't go bad, the vinegar can be used repeatedly. When the ginger is finished, add new ginger slices. If the vinegar is not enough, add new vinegar until all the ginger slices are not used.
Pay attention to water and oil-free every time you take ginger slices and add ginger slices newly, so as to avoid spoilage.
The habit of eating ice in summer has existed since ancient times. It is not a bad thing. It's just that it's too easy to get iced food now. Many people eat ice recklessly and end up eating bad.
To be sure, the refrigerator is a great invention, but whether it can bring benefits or disasters to mankind depends on how we use it.
It's understandable to eat ice in summer to cool off the heat, but you should also consider your own physique, and you should stop when enough is enough, and learn to repair your physical injuries in time.
