In the spring of 1983, Mr. Yang Zigeng, a Chinese scientist, wrote a symbol like a letter from heaven in a prison in the United States, which attracted great attention from both China and the United States. Both countries have set up expert groups to identify Mr. Yang Zigeng's symbol.

The CIA immediately invited Powell, an American symbol scientist, to the CIA's Langley headquarters to immediately identify the words written by Yang Zigeng, believing that there must be hidden secrets in these heavenly symbols, but they were soon disappointed.

Powell is a scientist in the study of symbols, but after reading the symbols written by Yang Zigeng, Powell shook his head and said: I believe he is already insane.

Nastasia, said: Why?

Powell said: I can tell you with certainty that these symbols are not human symbols, and I have not seen such symbols in all the symbols I have seen, and when I said this, Powell said thoughtfully: If I have seen them, they are alien symbols, but there is no such possibility, so I speculate that these symbols are imaginary symbols in the case of insanity, perhaps an expression of the thoughts of the imaginary, but they do not have any practical meaning for us.

Nastasia said to Powell: "Doctor, can you not jump to conclusions so quickly?" The person who wrote these symbols is a world-famous quantum research scientist, would he write them for no reason?

Powell said to Nastasia: I think that for the sake of prudence and responsibility to the country, I suggest that an expert group be set up to conduct consultations so as not to cause miscalculations. In fact, why do we need identification? Now that he's written it, can't he just let him speak? Can't you CIA make one person speak, that's your forte?

Nastasia said, "Mr. Powell, if he can speak, is there any point in us looking for you?"

Powell asked, saying, "Is it dead?"

Nastasia said: "If the CIA doesn't let a person die, he can't die, the problem is that he bit off his tongue, there is nothing new at all, he thinks he can't speak, we can't do anything about him, we will finally make him kneel down his noble head." Nastasia thought that Powell was already a world-famous scientist and symbol expert, and Powell said that these symbols were meaningless, so was there still a need to set up an expert group? So he said: We don't want to expand the scope of this matter, we just want to limit it to a limited scale.

Powell said a little dazedly: It stands to reason that he must have written these symbols with the intention of writing these symbols, at least he has the motivation to convey some kind of information through these symbols, according to Einstein's quantum entanglement theory, these symbols are just a point transmission, and the other party who receives the information must restore the entire information according to this point, so who does he want to pass this information to? Definitely his own country. Therefore, I suggest that these symbols are not easy to disclose to the public for the time being, and that they should be disclosed to the public after a result is identified.

Nastasia said: Mr. Powell's idea is very constructive, but it is too late, the whole world knows these symbols, and we will judge the Chinese scientist Yang Zigeng on the basis of these symbols.

Powell said: This Chinese science is really wise, and he designed this trap, and he just wanted to pass on these symbols of his through you, and you entered the trap according to his ideas.

Nastasia said: This damn old thing, he should be allowed to die, but the White House wants to keep him.

Powell said: I admire him, he does have a genius head.

When Powell was sent out of the Langley headquarters, another mysterious person was invited into the Langley headquarters, and he was the Chinese-American scientist Sun Yi. It is said that Sun Yi is an expert on China issues that the White House relies on, Sun Yi is proficient in the written languages of China's 56 ethnic groups, and is an authority on Chinese Chinese linguistics, and he is a descendant of Sun Tzu, who is known as a sage and prophet in China. At the same time, Sun Yi is also a Chinese who often goes in and out of Langley headquarters, in a sense, espionage is semiotics and philology, that is, the differences in words and symbols between countries have caused obstacles to intelligence exchange, but at the same time it also brings opportunities for intelligence exchange, obstacles and opportunities are the needs of espionage, the obstacle is that those unknown minority words and symbols are not known to people at all, and it is this obstacle that brings opportunities for intelligence transmission, that is to say, a secret intelligence is placed in front of you, You are even the medium of transmission, but you don't know it. Therefore, the CIA will ask Sun Yi for advice on all kinds of problems related to China. Sun Yi has become an American citizen, and in fact his identity is already American.

After reading the symbols written by Yang Zigeng, Sun Yi said: I can say with certainty that these symbols have nothing to do with the 56 ethnic scripts of China, or that they are not written at all, but just some symbols.

Nastasia said: Mentor, are you sure? The slightest deviation will be the biggest mistake in our lives, so don't jump to conclusions.

Sun Yi said thoughtfully: To be honest, with my experience and research, I have indeed never seen this kind of symbol.

Nastasia said: It is because of this strangeness that it is doubtful. Our job is to never believe in the world in front of us, because everything we see is illusory, and what we don't see is the truth, so our job is to doubt everything, doubt the world, and our misjudgment may be a disaster for the country.

Sun Yi said: I don't know what to say when you say this, or the expert group will conduct a consultation and then draw conclusions, and a person's knowledge will be limited.

Nastasia said: I think this is the only way, no one can afford this kind of responsibility, and immediately set up an expert group to consult.

Beijing, China.

Central Investigation Department.

Scientists from the National Academy of Sciences, symbolic experts from the Central Investigation Department, and cryptography experts were all there. Together, they identified Mr. Yang Zigeng's symbol picture. Everyone shook their heads and agreed that perhaps Mr. Yang Zigeng was really driven crazy, and the conclusion of the consultation was that the symbol left by Mr. Yang Zigeng had no meaning, or rather, no value.

Tang Weidong said: What I am worried about is that under the conditions of mental collapse in the special environment, is there any possibility that these symbols left by Mr. Yang Zigeng will leak the secrets of China's quantum research?

A quantum scientist from the National Academy of Sciences said: Since these symbols have not been identified for the time being, it is not possible to judge whether these symbols are involved in China's quantum research for the time being, and of course, it is impossible to judge whether they are leaked for the time being.

Zhao Hanbing said: This is terrible, the United States is using these symbols as evidence to convict Mr. Yang Zigeng of espionage in the United States, if we can't unravel what these symbols express, then how can we appeal to our righteous claims?

Tang Weidong said: Whether we appeal or not, they are all determined to convict Mr. Yang Zigeng. I thought, why did Mr. Yang Zigeng write these things? If it is just some worthless symbols, why should he write it? Before he wrote it, he must have understood that Americans could not understand it, nor did it write it for Americans, but it must have been written for us, but what did he want to express? You must know that Mr. Yang is a linguist, especially in China's minority languages and philology, as well as the world's languages and writings, and he changed his studies to science and engineering in order to serve the country with science.

Scientists from the National Academy of Sciences said: In this way, Mr. Yang should have left these symbols with his deep meaning, and perhaps he wrote down his key problems in quantum research in these symbols.

The cryptographic expert said: This is unlikely, didn't Mr. Yang consider the situation in case of a leak?

Symbol experts said: Because we don't know under what circumstances Mr. Yang wrote these symbols, and we don't know whether it was really Mr. Yang who wrote down the symbols, what was his motivation for leaving these symbols?

Tang Weidong said: Comrades, what I am worried about is the leakage, Mr. Yang is the core figure of our country's quantum research, in other words, he holds the core part of our country's quantum research. If the secret is leaked, it will be a devastating disaster for our country's quantum research, and if it were not, the United States would not do everything possible to force Mr. Yang to death.

A scientist from the National Academy of Sciences said: Comrade Wei Dong's worries are also our worries, and the problem is that if we can't recognize these symbols now, we can't talk about other problems.

Tang Weidong said unhappily: Aren't you symbol experts and cryptography experts experts? At least talk about some constructive ideas, one that is not recognized is the conclusion, so what do you experts do?

The symbol expert and the cryptography expert said: Comrade chief, we can't talk nonsense, we have to seek truth from facts.

Tang Weidong patted his head and said: You see I am in a daze, how can I forget someone, Minister Zhao, call Huang Weiguo.

Zhao Hanbing said: I've already thought of it, wasn't it sealed by you in the office of Huang Lao Revolutionary? I didn't come out even if I was killed.

Tang Weidong said: Let's go, look for him, rush to the doctor, try it, what does this "madman" think.

Tang Weidong led a group of people to my grandfather Huang Kexing's office, and said to my father Huang Weiguo at the door: Huang Weiguo, you come out and we will study the research problem.

My father Huang Weiguo said: I can't come out, I will die in this house, that Tang Weidong said, he is the chief, he gave the death order, I haven't found the key yet, so I can't come out.

Tang Weidong said: Don't you go crazy, can't you?

My father, Huang Weiguo, said: What madness is crazy? Are you crazy? What are so many of you doing here? Tang Weidong said, only I can enter this house, and others can't come in.

Tang Weidong said: Okay, okay, I won't come in, we won't come in, you can help us see what is written on this picture.

My father, Huang Weiguo, took the picture as if he was taken aback, and said, "Where did you get the picture?"

Tang Weidong said: Just tell us what is written on the picture?

My father Huang Weiguo said: You are looking for the right person, the symbols on these pictures are the words that have disappeared, the words of the Yiche people in Yunnan, now there are only oral expressions, the people who recognize these words in this world are only me except for my old man, I also know some, how can there be a third person to know? Who is this person? I want to see him?

Tang Weidong said: You just tell us, what is the content of the picture?

My father, Huang Weiguo, said: It's nothing, it's just a sentence.

Tang Weidong said: Say it quickly, what are you saying?

My father, Huang Weiguo, said: This sentence is "Farewell, my motherland".

Tang Weidong couldn't help crying, and a group of men all cried.

My father, Huang Weiguo, said: What are you crying about? That man was born immortal? However, these symbols do not seem to be so simple, and there seems to be something hidden inside.

Tang Weidong held back his crying and said: Tell me quickly, what is the content?

My father, Huang Weiguo, said: These symbols have been encrypted layer by layer, and all symbols convey wrong information, no matter which direction you study it, it is wrong, it is amazing, this person must be a genius. These symbols are even the world's most sophisticated semiologists and linguists, who cannot understand the representation of symbols. Even if someone understands a little meaning, they can only stay on fragmentary guesses, it can indeed be called a book from heaven, because it is simple but complex to the extreme, and its complexity is to the extreme of simplicity.

Tang Weidong said: Don't go around the bush, just talk about the content.

My father, Huang Weiguo, said: You think I'm a genius, I can't unravel it now.

Tang Weidong said: Then I will give you an order, this is your second task.

My father, Huang Weiguo, said: Who are you, do you think anyone can give me orders? I'm too busy, do you think you're Tang Weidong?

Tang Weidong couldn't cry or laugh, looking at my father Huang Weiguo, Tang Weidong said sadly: Weiguo, it's not that I forced you, I didn't force you, who did I force to go, if I wanted to be forced, I also had to be qualified?

My father Huang Weiguo said: What qualifications? Isn't your qualification to let me die?

Tang Weidong looked at my father Huang Weiguo and said: Weiguo, you tell me the truth, are you really crazy or fake crazy?

My father, Huang Weiguo, said: Can I be crazy? Am I qualified to be crazy? I'm crazy, can Tang Weidong spare me?

Tang Weidong said to Zhao Hanbing: Hurry up and send the guests away, I will talk to him here.

Watching a group of people leave, Tang Weidong felt a kind of desolation. Their lives are destined to be this desperate situation and helplessness. Tang Weidong took out a tissue to wipe the moist corners of his eyes again, he didn't want other men to see his sadness. The more difficult times like this, the more mission rises from the heart.
