After having such a bad feeling, at home, Liao Huansheng also tried not to sleep on the Tao pillow, hoping to get rid of the entanglement of those dreams, but with other pillows, insomnia struck again, and this time even sleeping pills were no longer effective, making him unable to sleep all night. Pen ~ Fun ~ Pavilion www.biquge.info Liao Huansheng sometimes reads a book all night, until the day is bright, he can sleep for a while, but there is a little sound, and he will wake up, so a month later, Liao Huansheng has a haggard face and can not bear the pain.

But after Liao Huansheng and Feng Bu came to my courtyard once, they suddenly found that it was easy for him to fall asleep with me, and he slept very deeply, even if he had some strange dreams, he would forget them all when he woke up. So, he found all kinds of reasons to come to my house to sleep, although he also knew that this would not solve any problems, but in order to get a good night's sleep, the rest could be put down first.

After saying this, Liao Huanchang breathed a sigh of relief, as if he had unloaded a thousand catties of burden, smiled at us, and said: "My story is not as exciting as Lu Liu's story. I'm completely haunted by strange dreams, thinking that I can control the pottery pillow, but in the end I am confused by things, ashamed, ashamed. ”

Liao Huansheng said this somewhat depressed, and Zeng Qian, who had not spoken, spoke at this time. "Lao Liao, you studied physics, and you taught automation at the university, you should have done research on what Tao Zhen caused, right?"

Liao Huansheng nodded, and he could say that he had turned over and over the pottery pillow, and studied it thoroughly. Liao Huansheng is not very interested in cultural toys, but he still spent some effort on the pottery pillow, and saw a lot of similar objects. He compared the porcelain pillow, and still found that his pottery pillow is a little different, one is, in terms of shape, the protrusions at both ends of the pottery pillow are higher than the general one, like two semicircular flares, the center is a little inverted, semi-arc-shaped, in Liao Huansheng's view, this is like the receiving surface of the radar, lying in the middle, the ear is just in the center of the receiving surface, so the sound reflected by the receiving surface is actually naturally amplified, and it is easier to be heard.

The other is that the bottom of the pillow is hollow, and there are many original holes, which are arranged in a net, each about the size of a five-cent coin, and there are more than 20 round holes in total. Initially, Liao Huansheng thought that these holes were for ventilation, to keep the air circulating, and it would be cooler to sleep in the summer. But later Feng only told him that the holes on the pottery pillow and porcelain pillow were mainly opened for fear of uneven temperature in the kiln during firing, resulting in cracking, but generally only one or two were opened, and many were still opened on the side and surface. But this kind of underside is full of round holes, and he has never seen it.

Liao Huansheng carefully studied the pottery pillow again, and he found that the round hole is not only the bottom layer, but also a layer of pottery plate in the center of the pottery pillow, and there are also round holes on the pottery plate, but it is staggered with the hole at the bottom layer. Liao Huansheng drew a simple sketch on paper, handed it to us, and then explained to us that this is like a resonance box, which has the effect of amplifying sound, and the multi-layer hole structure should be a special tuner, a simple decomposition device for high and low frequency sounds. Maybe there are several layers of perforated pottery plates inside, and it is difficult to see its true structure without breaking the pottery pillow, but the sound should be further filtered after the pottery pillow, and the reason why it is easy for him to fall asleep on the pillow is because his ears hear a large number of low-frequency sounds.

But Liao Huansheng understands that there is no direct relationship between sound and dreams, and low-frequency sounds may stimulate a certain area of the cerebral cortex and stimulate the formation of people's dreams, but it is impossible to affect a person's dreams or change the content of dreams, so the problem should not be in the pillow itself, but the change in the sound it receives. This is also the fundamental reason why he no longer dared to put Wenyu next to his pillow.

A few years ago, our research institute studied a strange person who could understand bird language, and later found that he was not distinguished by the length of the birdsong, the tone of the voice, but because the structure of his ears is different from that of ordinary people, he can hear some high-frequency sounds, which is similar to the hearing of some birds, so the birdsong he hears is completely different from what ordinary people hear, and it is easier to analyze the meaning from the song。 Zeng Qian poured tea into Liao Huansheng's empty cup, but her analysis seemed to give everyone a vague glimpse of the way to solve the mystery.

"Xiao Zeng, go on. Liao Huansheng said with some urgency.

"I remember Uncle Chang told me before, how to look at the problem of ghosts and gods, why did the ancients insist on dividing unknown invisible things into gods, ghosts, demons, and foxes? Ghosts and gods are spiritual things left by the ancients, good, good, and wise are called gods, bad, evil, and vicious resentments are called ghosts, and demon foxes are individuals with physical existence and cultivation, but they are different from the animals themselves. It turned out that I didn't take Uncle Chang's words seriously and listened to them as stories, but now that I think about it, it still makes sense. If ghosts and gods are a kind of spiritual substance, then its existence may also be like sound, a kind of frequency vibration, why can some people perceive it, and some people cannot? These, Uncle Chang, you can talk about it, I only know a little bit about it. Zeng Qian winked at me and poured me tea.

"Xiao Zeng, what you said is very right, but these cannot be proved by existing science, and we don't have to be busy making conclusions, I want to start with the pillow itself, maybe I can comprehend the avenue between heaven and earth like Lu Sheng in a dream. I picked up the fragrant tea and took a sip on my lips.

"Who is Lu Sheng, do you know Lao Liao?" asked Team Cao, looking at me in surprise.

"Don't worry, you'll know in a moment. The origin of the pillow, it is difficult for us to make a conclusion now, but at least five or six thousand years ago, Egypt and ancient Babylon already had pillows, but at that time the pillow was more related to witchcraft and priests, not everyone could use it, it was a tool for priests to communicate with the gods, then this should be related to dreams, so Egyptian priests often wore a pillow-shaped amulet. In China, the pillow has a history of thousands of years, but the homology of Eastern and Western civilizations is verified here, the pillow was the earliest sacrificial vessel, is the spiritual vessel, especially the stone pillow and jade pillow, rarely really used, which is why the pillow is rarely handed down, mostly out of the tomb. After saying this, Liao Huansheng's face turned pale, and thoughtfully, I patted his trembling legs and continued.

In folklore, the invention of the pillow fell on Cao Cao's body, it is said that when he was young, he fought in all directions, often fell asleep in the camp tent looking at the official documents, and his soldiers used a wooden box to pillow under his neck, so that he could sleep more comfortably, and later simply carved a wooden pillow with two large ends and a thin middle with a log, so that there was a pillow. Of course, this legend is not believable, but why did this legend be added to Cao Cao's body?

"Cao Cao is still the ancestor of an industry, this, Lao Liao should have heard of it, right?"

"Lao Chang, do you mean tomb robbers? This Feng has told me, and I am a little impressed. Liao Huansheng sat up straight on the sofa and looked at me intently.

"Yes, at the end of the Eastern Han Dynasty, the princes were divided, although Cao Cao coerced the Son of Heaven to order the princes, but he still had a tight position in his hands, in order to raise military expenses, set up Faqiu and touch the gold school captain, engaged in special tomb robbery work, and later the hair mound and the touch gold became the two major schools of tomb robbing. But as the founder of the sect, it is impossible to create an industry out of thin air without relevant professional knowledge, right? But where did Cao Cao's knowledge of tomb robbing come from? If the pillow is the medium of yin and yang communication, then Cao Cao has an inherent possibility to become the ancestor of the two industries. But these are legends, there is no real evidence, and everyone can listen to them as stories. If it's a story, we can go on and on. ”

Later, Cao Cao suffered from a serious headache, according to today's statement is estimated to be neurasthenia or migraine, from historical records, this disease was relatively rare at that time, because the famous doctors at that time did not have any cases of treatment, so Hua Tuo was invited, Hua Tuo wanted to give Cao Cao a craniotomy, this is of course a bit unbelievable, Cao Cao did not dare, thought that Hua Tuo wanted to harm him, so Hua Tuo was executed. However, Hua Tuo only proposed a treatment plan to Cao Cao, and did not implement it, besides, Hua Tuo is the only person with a cure record for this kind of disease, and if there is a risky plan, there must be a conservative treatment plan. Then there can only be one explanation. Speaking of this, I looked at Liao Huansheng again, and he seemed to realize something, his lips moved slightly, but he still didn't make a sound.

"Uncle Chang, are you saying that Hua Tuo discovered the cause of Cao Cao's headache, maybe it is related to his pillow for a long time? And the pillow contains an ulterior secret, maybe it is the matter of hair mound and touching gold, after all, digging up the tombs of ancestors is morally unspeakable. Cao Cao didn't kill him because of his treatment plan, but because he knew too many secrets?" Zeng Qian said, shaking her head.

"As I said, these are just stories, we're retelling stories, maybe it never happened. But these stories have to do with pillows. I slowly lit a cigarette, watched the smoke disperse little by little in the hut, the cool breeze of the autumn night gently pushed open the door, Cao Team shivered, hurriedly got up, locked the door, and closed the window with his hand.

(Therefore, people in the world do not know where life comes from, Gai Shen parents are not alive; where death comes from, know where they come and then know where they are born.) People in the world do not ask where death comes from, after the soul of Gai Shen descends, where life goes, know where to go and then know where to die. The opportunity to die is due to life, and the opportunity to live is born from death. No death, no death, no life. The opportunity of life and death is related, so people in the world have life and death, and the opportunity of life and death is not related, so people are beyond life and death. There are those who live and die, and there are those who do not live and die, and there are no people who are alive and dead, and there is also the heart. If you are restored, your heart will be born, and if you are lost, your heart will die. The dangerous can be safe, and the deceased can be protected. --"The Purpose of Life") (To be continued.) )
