I am doing an activity, that is, answering questions correctly and giving gifts. But I don't know how to create problems! Wait for netizens!

Master Wang sells shoes. The purchase price of a pair of shoes is 30 yuan, 20 yuan, with a 20% discount on National Day. The customer came to buy shoes and gave a 50. Master Wang had no change, so he asked his neighbor to change 50 yuan. Afterwards, the neighbor found out that the money was real, and Master Wang didn't pay his neighbor 50 yuan. How much did Master Wang lose?

The school held a math contest, and five students won the top five. Before awarding prizes, the teacher asked them to guess their personal rankings. They said: third place, fifth place; Say: fourth place, fifth place; Say: first place, fourth place; Say: first place, second place; Say: third place, fourth place. The teacher said: Everyone guessed the ranking correctly. Q: How are these five students ranked? First place, second place, third place, fourth place and fifth place. Tell me about it.

At the beginning of 2006, after a lapse of 1 1 year, Zhu Lingan once again triggered a big discussion on the Internet. It shows that everyone has not forgotten this gourd case because of the passage of time, and it also shows the powerful role of public voice and justice represented by the Internet in maintaining social fairness. 1 1 year is not an earth-shaking change, but it is also a long life time for the parties. If there is no further discussion on the internet, it may be forgotten after the first public attention 1 1 year; Thus, the purpose of the real murderer was finally realized: mixing water, then using the word "drag", and finally letting the matter go away. Unfortunately, the network once again frustrated the murderer's plan-after a lapse of 1 1 year, just a few posts once again aroused the public's attention.

The Internet is changing our life completely. It is conceivable that without the Internet, Zhu Lingan would not have launched a nationwide truth and fair investigation. In most cases, the network represents the voice of the public, represents the just position, and truly represents the trend of the times is the correct public opinion orientation. Any blockade and containment of the Internet is absolutely forbidden, and it is beneficial to a few people. For example, Zhu Lingan, the real culprit behind it, has also eloquently proved the truth of this Internet age.

Let's not discuss the details of the case (see below for details). There are numerous online discussions, and there are different opinions on various plots, evidences and speculations. Truth and facts have been mixed together, and when they are false, they are true. Now, only by discussing it online will it attract the public's attention again at most, and then it is possible to find out the recognized biggest suspect-it is impossible to finally close the case. However, what deserves our attention and consideration most is, why can't the public security organs draw a conclusion about such a country 1 1 year, a vicious homicide case of national concern? Because of well-known reasons, the public security department was "ordered" to stop the investigation of this case-this is really a big joke and scandal: such a big case that the whole country is generally concerned about, the so-called "people's" public security can actually resist the saliva pressure of more than 654.38 billion people, resist the national questioning of truth and justice, and stop the investigation of this case! Especially when the mystery of this case caused a national discussion, when many netizens were enthusiastically discussing the course and truth of the case, the public security department, which should be duty-bound to take the taxpayer's money to investigate the case, could stay out of it and pretend not to know! Next time, if someone wearing a police badge bluffs in front of you with the so-called "civic duty, people's public security is a sacred authority entrusted by the people and the state", everyone can stand up and ask him about this case!

This strange phenomenon itself is also easy to arouse people's association-who can have such strength to prevent the operation of a huge and powerful National Security Agency? ! China police, as long as they are determined to find out a case, no matter how complicated the case is, there will always be a day to find out-the only question is how the high-level means are used and how much money and time they spend. If we can't find the real culprit, according to their performance in She Xianglin and other cases, we will at least find a scapegoat to prevaricate the pressure from superiors and the public and solve the case unnoticed.

It can be seen that, in the final analysis, the crux of this case is not who has been exposed to thallium, who has been enemies with Zhu Ling, the character of the suspect Sun Wei, or the interpersonal relationship in Zhu Ling's class ... These are trivial issues, and netizens will not be conclusive after discussing them for several years! The crux of the problem lies in why 10 for many years, the well-connected public security organs have been helpless in the face of a criminal suspect (most likely a student rather than a professional killer)-is it impossible, unwilling or afraid? The netizen's statement broke the secret, and the parties also appeared to defend themselves one by one-but did the public security department that should really investigate the case say anything? ! With a powerful state machine, the security department with "sacred authority" will not move. Will there be any result when everyone quarrels? ! So, let's not waste time. Perhaps, turning the focus of discussion to the Public Security Bureau may force something truly authoritative and valuable. ...

The facts are complicated and changeable, and the truth and rumors are flying all over the sky. But at least, the remarks made by Bei Zhicheng and Sun Wei recently should be my responsible speeches after careful consideration. Then I will only start with these two statements to prove the author's guess about the murderer. In fact, judging from these two statements, there is not much suspense about who the murderer is, just waiting for the final confirmation of the authoritative department.

First of all, it is worth noting that both sides have stated some facts, and not every point has been mentioned by both sides and used to support their arguments. We can see that the attacker Bei Zhicheng mentioned a lot of noteworthy and reliable evidence, which was not involved in Sun Wei's statement. Why does this evidence give Sun Wei the most suspicion? After ten years of silence, Sun Wei published a document himself, but he was obviously trying to avoid it? If we can make these questions clear, it will undoubtedly eliminate our doubts to the greatest extent, so why doesn't Sun Wei make it clear? ! The following two points list the major doubts mentioned by Bei Zhicheng and avoided by Sun Wei in the statement;

The police found Zhu Ling's water cup in Sun Wei's box. -If it is true that Sun Wei said that he is completely innocent and has a "good relationship" with Zhu Ling, then why do you want to hide this vital material evidence (thallium salt entered the body from Zhu Ling's diet, so can you find residual substances on the drinking cup? ) Why didn't Sun Wei explain it publicly in the statement?

There is a rumor in Tsinghua that Zhu Ling's father smuggled thallium salt, and Zhu Ling accidentally polluted it, so he was poisoned. Later, the police confirmed that the maker of this rumor was Sun Wei. If Sun is innocent, and according to her statement, "there is nothing wrong with the relationship", then why create such ulterior motives? If Sun Wei is innocent, why did he take the initiative to get involved in this case in this way, creating chaos and exonerating potential suspects? Why didn't Sun Wei clarify such obvious doubts in his lengthy statement of self-defense?

Looking at Sun Wei's self-defense, there are many flaws to be grasped: (italicized words are quoted from Sun Wei's statement)

3. "Last year, I was even named as the murderer on the Internet. I want to stand up and explain, but I think, after all, the case has not been solved, and how Zhu Ling was poisoned is still a mystery. The space of imagination is infinite. If someone thinks I am the murderer, any explanation will arouse new doubts, lead to more heated discussions and more rumors, which is the sorrow of the wronged! So I decided to keep silent. When some friends who knew the situation angrily wanted to help me refute, my family and I dissuaded them. "

& lt！ -[If! supportLineBreakNewLine]-& gt；

& lt！ -[endif]-& gt；

This is confusing the audience: the most effective way to dispel doubts is to stand up and defend yourself publicly. The more the truth is argued, the clearer it becomes. Everyone is not a fool. Both sides know who is right and who is wrong. Sun Wei, on the other hand, said that silence is to rule out his own doubts-this is obviously illogical. On the other hand, it makes people feel that Sun Wei's ten-year silence is very suspicious-if his innocence can be clarified, why didn't he say it earlier? When people paid attention to this matter again after taking the blame for 10 years, Sun Wei was forced to stand up and defend himself when questioned by many people around him? If you have a clear conscience, you should be able to face the truth fearlessly and defend yourself openly at any time!

4, about the legend of the so-called Sun Wei's grandfather pleaded with senior leaders, Sun Wei argued:

It is widely rumored on the Internet that the supreme leader visited my grandfather before his death, and grandpa "took the hand of the supreme leader" and demanded that "my granddaughter be spared". And "the police chief flew into a rage, saying that everything was stuffed into his mother's mouth, and all the deaths were packed in sacks", and so on. So vivid, as if the author were on the scene. Such a vicious and insidious fabrication is outrageous.

As a matter of fact, the first and only time the public security organs questioned me was on1April 2, 997. And my grandfather199565438+died on February 9th. If what this "writer" said is true, wouldn't it be that yin and yang can also speak? ! And I haven't been locked up for a day, let alone "released"

1April 2, 997, when the police asked about my family members, I only mentioned my father, mother and brother. When I asked others, I only said that my grandparents had died, and I didn't even mention their names.

Grandpa is my favorite person. He was patriotic and dedicated all his life, honest and honest, and hated corruption the most. Before his death, he left his last words many times: do medical anatomy on the remains, donate useful tissues and organs, use the rest as fertilizer, green the motherland, simplify the funeral and donate all his savings. His ashes were scattered under the tree without trace, and all his savings were donated to the school in his hometown.

For such an old man who has passed away, it is very shameful to fabricate such a false story on him!

Grandfather was Sun, the former vice chairman of China Revolutionary Committee, who died in February 1995-now that this matter has been involved, it is not good to hide it instead of putting it on the table. In this regard, I quoted a netizen as saying: "Here, Sun Wei did not give a detailed explanation of this incident. She just cleverly made a time difference in two sentences to let the readers read their own meaning, which is completely different from what she said before. Why is this happening? Why didn't Sun Wei make it clear that Grandpa had never been involved in this matter? I can understand that even if there is hard evidence like pleading in the future, Sun Wei can still be in a position where she can attack and retreat, because she didn't make it clear at first, which is very consistent with the rigorous style of the whole article. After a closer look, the problem will come out even more. As we all know, Zhu Ling's poisoning occurred at the end of 1994, and he was diagnosed as thallium poisoning in April of 1995. 1May, 995, the public security filed a case for investigation. During this period, Zhu Ling's classmates and friends were investigated. At this time, through various details and testimony (Zhu was not insane at that time), as the biggest suspect, his family, Bei Zhicheng and the police have brought him to the surface. Please watch the time. From1May 1995 to1February 1995, Sun's grandfather was still alive, which was enough to make many things happen. However, here, Sun Wei once again adopted selective forgetting, and she only mentioned the first trial in 1997-what happened to Sun Wei after filing the case? She just replaced it with a few words. Sun Wei described himself here as a completely innocent person during the two years of the crime, which is inconsistent with the information obtained by Bei Zhicheng and many channels. Bei made it clear that the police would be listed as a major suspect a few months after the case was filed, and they were interrogated many times. Therefore, there must be one person lying on both sides. Who is lying? In fact, it is not difficult to find the correct answer by looking through the cases of that year. "

If Sun Wei was listed as a key suspect by the police in the middle of 1995, why can't Grandpa Sun Wei, who died at the end of 1995, plead for his granddaughter?

Sun Wei claimed in her defense that she was only questioned by the police at 1997 (it seems that Sun Wei was never suspected before 1997, but in fact she was already a major suspect at 1995! ), so it is impossible for 1995' s deceased grandfather to intercede for himself, which obviously confuses the facts. The so-called "release" problem. Sun Wei obviously used a polysemous word here, trying to confuse the audience again: Grandpa asked the leader to "release" Sun Wei, and the explanation of the word "release" can be "release from the public security bureau", or it is more likely that it means "let go, don't pursue it"; The "release" denounced by the police chief as "releasing the sack after killing" actually refers to "releasing from the police station", but we should think that as the police chief, you can "arrest" a key suspect at any time, so it is completely logical for the police chief to claim that it is impossible to "release" a person without being detained in Sun Wei, because he can arrest you at any time. Sun Wei also mentioned that his grandfather was an honest and good official, and listed the disposal methods of his dead body, ashes and inheritance. To prove that his grandfather could not have broken the law. However, if you use your head a little, you will know that after the death of senior officials in China, almost all the bodies and legacies are handled according to the above examples. This is a convention, not just to prove how selfless your grandfather is! In fact, cases of senior officials pleading for future generations and demanding "leniency" have emerged one after another in China politics. Anyone who knows the inside story should realize that this is nothing new-Sun Wei himself should certainly know better. Therefore, she used this obviously imprecise logic to try to excuse her family, which is obviously more confusing! What's more, there is more than one high-level background of saying, and there is also a neglected vice chairman of the Chinese People's Political Consultative Conference, Sun Fuling. !

Therefore, Sun Wei's self-defense about "pleading at the top" is completely untenable.

5. Attitude towards public security.

As I said before, the public security attitude in this case is ambiguous, which is recognized by everyone. However, in his defense, Sun Wei repeatedly proved his innocence with the arguments that "the police withdrew their doubts about me" and "the public security department thought it unnecessary to lie to me". The public security department involved in this case is unreliable, and the case will not be discussed without results 1 1 year! What a joke! -everyone knows this truth. How can the party Sun Wei not understand? ! Then why did Sun Wei prove his innocence again and again with the open attitude of the police? This is another serious suspicion of misleading the public and confusing people. After being silent for more than 10 years, Sun Wei suddenly published an elaborate defense to defend himself publicly, but this low-level logic that fools the public can be seen everywhere-Sun Wei, do you think you and Zhu Ling's Peking University Tsinghua classmates are idiots?
