On this night, the moon and stars were scarce. The silvery moonlight sprinkled on the reckless field, as if the whole earth was covered with a layer of frost. Such a scene makes the earth seem to fall into a deep sleep after a day of steaming in early summer, and even the restless dust slowly calms down. Although the early summer sun is not very scorching, it can also torture people standing in the sun and being exposed to the sun.

For the Yellow Turban Army besieging the city, a day's exposure to the sun is undoubtedly much more comfortable than the severe cold of winter, at least there is no need to worry about freezing and starving to death in the cold wind.

At night, most of the Yellow Turban Army, which did not have tents, continued to be baptized by the cold wind, and the considerable temperature difference between day and night was indeed a test for those who did not have enough food and clothing. Fortunately, the commander Bocai was aware of the situation, and always ordered everyone to boil some hot water to drink at night, so that everyone could survive the cold night of early summer.

However, even on moonlit nights, the Yellow Turbans, who lack food and clothing, find it difficult to see what is not far away. Why? Blindfolded finches.

The so-called "blindfolding" refers to poor vision or complete inability to see things in a dark environment or at night, resulting in poor vision and difficulty in moving at night or in a dimly lit environment. This was later known as "night blindness" in later medical science.

In ancient China, most people suffered from night blindness, which is largely related to the recipes of the ancients in our country.

Most of the night blindness suffered by the ancient people in China was "temporary night blindness". This is due to a lack of vitamin A in the diet or due to certain digestive diseases that affect the absorption of vitamin A, resulting in retinal rod cells not having the raw material to synthesize rhodopsin, resulting in night blindness. To put it simply, it is a lack of vitamin A in the body.

This kind of night blindness is temporary, as long as you eat more pork liver, carrots, cod liver oil, etc., you can make up for the deficiency of vitamin A, and then it will be cured quickly.

So here's the point, how to treat night blindness? As long as you eat more animal liver or carrots and supplement vitamin A in the body, you can be cured quickly. However, for the common people, who generally eat corn porridge as a staple food of pickles, eating animal liver is undoubtedly an extreme luxury.

Due to the low productivity and brutal exploitation of the ruling class, it is not easy for ordinary people to eat meat. Mencius's ideal picture of the "royal paradise" described to King Xuan of Qi said: "A house of five acres, a tree with mulberry, fifty people can be clothed, chickens, guinea dogs, and animals, if there is no time, seventy people can eat meat." (See Mencius, King Hui of Liang I)

In the Confucian tradition of respecting the elderly, Mencius's words will never be because the young people are full, and it is the turn of the elderly over 70 to eat meat.

In fact, the ancient rulers had strict restrictions on eating meat. The ritual system of the Zhou Dynasty stipulated that the Son of Heaven ate cattle; The princes usually eat sheep, and cattle can only be eaten on the first day of the new month (the first day of each month); The doctor usually eats pigs and dogs, and only sheep can be eaten in the new moon. At that time, the emperor and nobles prepared food at the beginning of each month, which was more abundant than usual, called "shoshi", and the food standard was also improved by one grade. In addition, during the sacrifice or the banquet held by the Son of Heaven and the princes, the doctor was able to eat the cow.

And the "Book of Rites: The Royal System" clearly stipulates: "The princes do not kill cattle for no reason, the doctors do not kill sheep for no reason, the scholars do not kill dogs and pigs for no reason, and the common people do not eat treasures for no reason." ”

Although Mencius's remarks can be seen that the Zhou rites have long been abolished during the Warring States Period, even Confucianism, which advocates the revival of the Zhou rites, has begun to "abandon its dross". However, from Mencius's words, a conclusion can also be drawn: "Even if a commoner has chickens, ducks, pigs, dogs, and other domestic animals, they can't afford to eat meat." ”

Why? Because human beings are social animals, they have to participate in social activities. And even in the era of smallholder economies, which were known for their self-sufficiency, farmers had to engage in business. Why did Emperor Wu of the Han Dynasty nationalize the profits of salt and iron? Because the daily life of ordinary people is inseparable from salt, the importance of salt does not need to be repeated; And no matter how poor the family is, there must be pots and pans, right? Knives for chopping vegetables aside, pots for cooking rice are always a must-have, right?

Of course, Emperor Wu of the Han Dynasty also had the purpose of nationalizing the power to make money, but it is only to explain that the peasants in ancient times also had to carry out an exchange economy. Feeding a little domestic animal and selling it in an emergency can also ensure that the family can tide over the difficulties, and the common people are reluctant to eat it. This is the so-called: "Those who are all over the world are not silkworm breeders", right?

So someone said, if you can't afford to eat meat, you can eat carrots, carrots are cheap.

Yes, in the current market, the price of carrots cannot be compared with meat, but do you know why carrots are called "carrots"?

Because the radish native to our country has fleshy roots, oblong, spherical or conical, and white, red or green skin, it is commonly known as "water radish".

The main components of radish are protein, sugars, B vitamins and a lot of vitamin C, as well as iron, calcium, phosphorus and fiber, mustard oil and amylase. Moreover, the vitamin C content of radish is nearly 10 times higher than that of fruits such as apples and pears. In traditional Chinese medicine, it has the effects of eliminating stagnation, dissolving phlegm and clearing heat, widening the lower qi, and detoxifying. However, it is a pity that the vitamin A contained in "radish" has not been found so far.

"Carrots", on the other hand, are imported like cucumbers, sesame, stools, peppers, and beards (oh, this is not). Although cucumber and sesame seeds have long been renamed, in Japan, which advocates Middle-earth culture, it still uses its original name in the Central Plains. The "creation" of this name by our ancients is exactly the same as the "foreign car", "foreign fire", "foreign oil", and even "foreign people" in later generations.

In ancient times, the surrounding ethnic minorities outside the Central Plains were all called, and the ethnic minorities in the east, west, north and south were called: "Dongyi, Xirong, Nanban, and Beihu". Among them, "Beihu" refers to the ethnic groups in the northern borderlands and the Western Regions. And "Hu" is a name for their own nation by the Xiongnu, a once prosperous northern people.

Because these items came from the north, they were given the word "Hu". In modern times, many new things have been passed from the West, and the word "foreign" has been added, which has a demeaning meaning. Sometimes, our ancestors create new words, and they are so simple and clear, straight to the point, without the slightest need to use their brains.

The "carrot", which is crucial here, is native to southwest Asia, introduced to the European continent from Iran in the 10th century, about the 13th century, carrots were introduced from Iran to China, developed into the Chinese ecotype, seen in England in the 15th century, developed into the European ecotype, introduced to the United States in the 16th century, and introduced from China to Japan in the 16th century.

Yes, you read that right, carrots were introduced to China in the thirteenth century, at this time, around the end of the Southern Song Dynasty. Therefore, interested friends can let go of their brains, maybe the carrots were brought from Iran by the Mongol expeditionary force? Therefore, it cannot be said that the original Mongolian iron cavalry was a reckless man who only knew how to kill, and they at least solved the problem of night blindness among the broad masses of the people in China for thousands of years.

At present, under the city of Changshe, the vast majority of the 200,000 Yellow Turban soldiers who cannot afford to eat animal liver and do not have carrots to gnaw on are actually suffering from night blindness.

Guo Bin's hundreds of elite iron horsemen are different. To say that they are elite is not only that they are physically strong, well-equipped and well-trained, but also that they are treated very well.

Since Guo Bin first established himself in Fulong Villa and tried his best to solve the people's food problem, meat has played a great role. Because meat carries hunger, it can provide more energy than corn porridge. Later, when soap was made, the animal oil residue produced became a delicacy on people's tables. Therefore, the people in Fulong Villa have been eating meat in their daily lives since nearly a year ago. Of course, the internal organs of the animals must also be cleaned and served to everyone's table. Even ordinary people have such treatment, not to mention the soldiers of Fulong Villa, which is known for their excellent treatment.

Because Guo Bin, a history lover of two knives, has seen information about how most of the ancient people suffered from night blindness because of dietary problems. Therefore, he consciously added animal liver to the table in the army. Therefore, if we talk about the entire Central Plains at present, which army has the fewest night blindness? Undoubtedly, it is Guo Bin's part; If you say that on the Central Plains territory now, which army is the most suitable for night fighting? There is no doubt that it is still Guo Bin's part.

Therefore, after the vast majority of the Yellow Turban Army fell asleep, Guo Bin's 700 cavalry bundled horses and horses to the east of Changshe City, the periphery of the Yellow Turban Army camp.

Unlike the brightly lit city of Changshe, which seemed to be facing a great enemy, the entire Yellow Turban Army camp was neither protected by a wall, nor was there a sergeant patrolling vigil, and there were even few torches for lighting. Seeing this situation, Guo Bin didn't know whether to say that the Yellow Turban Army was overwhelmed and courageous? There is still a lack of experience in war. Even if you walk the rivers and lakes, you also have to burn a fire, not only to drive away mosquitoes, but also to intimidate wild beasts, right?

Guo Bin asked Guan Yu to lead the army to lurk, and he took Zhang Fei to dismount and march to the camp of the Yellow Turban Army.

Most of the Yellow Turbans were made up of displaced people who had lost their land, and most of them cut the weeds on the ground, spread them under their bodies as beds, and slept directly in the unsheltered wilderness. Maybe it was because the work of scolding the war during the day was too tiring, or maybe it was not enough to eat, resulting in no energy and fatigue one by one, Guo Bin and the others walked around the camp for nearly half an hour, but no one noticed.

Although some soldiers of the Yellow Turban Army who got up at night saw the two of them, when they looked at the armor of the two of them, only those who respectfully retreated to the side, who dared to come up and question the two? Also, the Yellow Turban Army even broke the state county, and the weapons and armor collected in the arsenals in each city were divided among the commanders of the Yellow Turban Army, and it was not so surprising that two people wearing official armor occasionally appeared to inspect the camp.

However, it can also be known from this that in the Yellow Turban Army, the soldiers do not know the generals, the generals do not know the soldiers, and the soldiers who patrol the night do not even have a password, saying that they are stragglers are praising them.
