vpay365 is similar to Alipay's payment platform, pull the head back to the day, the total return to 10/1000, and you pull the head to give you a rebate. It's just a new payment tool, which is based on the real scene and the quantification of trust between people, that is, the payment method based on digitization. The ways to judge whether the pyramid scheme is implemented are as follows:
1; Capitation fee; Or & quot; Qualification fee & quot; Or pay in disguised form by subscribing for goods (including services) & quot; Capitation fee; Or & quot; Qualification fee & quot; Obtain the qualification to join or introce others to join
2. By introcing others to participate in the development of offline personnel, an organizational system with internal wealth redistribution relationship between the upper and lower levels is established
3. The organizer uses part of the expenses paid by the participants to pay the first participants to maintain the operation; The income of participants is determined by the order of joining and the number of development personnel.
pyramid selling is one of the multi-level direct selling. The main difference is that pyramid selling charges high membership fees, while multi-level direct selling generally does not or does not receive less membership fees It can be seen from this that the high membership fee charged by MLM is a kind of naked fraud, and its harm has been widely recognized
extended information:
the characteristics of MLM: the ultimate rights and interests of most consumers or investors are not protected. Let's compare MLM with normal marketing one by one for your identification
the consumption behavior and the management behavior are vague, the MLM marketers use some "tricks" to publicize the investment management behavior for you in the early stage, and then you become a consumer unconsciously; Or the propaganda is consumer behavior, later let you become an investor; Even quoting vague concepts such as "consumption capitalization" makes you lost between investment and consumption, which brings a lot of difficulties to your legal rights protection (Note: consumption behavior and investment management behavior are two different legal concepts, applicable laws are: Consumer Protection Law and contract law)
in the name of marketing goods, providing services, project investment and other business activities, the organization and leaders require the participants to pay fees or purchase goods, services, investment and other ways to obtain the qualification
in the regulations on the prohibition of pyramid selling, the concept of hierarchical relationship is repeatedly mentioned. The formation of hierarchical relationship is only one of the phenomena in many pyramid selling. It must be related to the illegal possession of other people's property before it can be suspected of pyramid selling. For example, there are five or six levels of commodities in village level community stores, which is normal sales. Therefore, the object of MLM infringement is complex. MLM is often accompanied by tax evasion, bid up prices and other phenomena, which infringes many social relations and legal objects; There must be two elements of the main object: 1. Fraud (infringement of citizens' property ownership); 2; 2. Disturbing social management order and economic order
essence
the target of MLM sales is to buy the company's procts by themselves and promote this sales method to the offline. In fact, the offline sales mainly focus on their relatives and friends. This kind of sales mode damages the interests of the salesmen, and it will not bring any reward to the offline salesmen, on the contrary, it also causes losses, And in the process of sales to their own is not to learn any sales technical experience, only to sell their procts to him need skills. So this kind of way is not a normal work at all, but a kind of deception that harms others and oneself and makes huge profits for a few top-level online
The internal management of MLM is paramilitary, which has been highly organized and violent. MLM personnel violently resist the law or gather people to attack the state organs. In Shanxi, Beijing and other places, MLM personnel attack the public security organs one after another The essential difference between pyramid selling and direct selling is that direct selling belongs to business activities, while pyramid selling is financial activities and fraud3. I don't think you need to hang up. Just fight for what you want to do!
4. Those two letters, called "Guanzi", are used to distinguish the printing batches. After the unified arrangement by the people's Bank of China, they are instructed to be used by the banknote printing factories when printing banknotes. The number after the crown represents the printing order of each note in the batch
according to the crown and number of the note, combined with the record of the note printing file, the proction source of any note can be traced
there are 26 English letters without V and 25 more. There are ten groups from a to j, five groups from klmno, and ten groups from P to Z. These three groups match with each other, or with themselves, forming nine groups. The batches printed in RMB are in the order of large groups. Specifically, the fourth and fifth sets have different names for large groups, so I will not elaborate here
as for the number, each prefix starts from 00000001 and ends at 100000000 (note eight zeros), with a total of 100 million
generally speaking, you can't judge whether it's true or false from the collocation of letters and numbers, unless the letter appears V or the number of digits is wrong
in addition to its other characteristics, the single crown number of RMB in China has many differences. So what is the crown number? The word "crown" is the symbol printed in front of the number on the ticket; Prefix & quot;, A number used to indicate the number of tickets printed; Prefix & quot; The people's Bank of China issues RMB with Roman numerals (Ⅰ, Ⅱ, Ⅲ, Ⅳ, Ⅵ, Ⅶ, Ⅷ, Ⅸx) as its prefix; The Arabic numeral after the crown is the number, which is used to indicate the number of tickets printed. The fourth and fifth sets of RMB use the capital Chinese phonetic alphabet as the crown, which is the first time in RMB
according to the crown and number of the note, combined with the record of the note printing file, the proction source of any note can be traced

5. In the public's impression, the banknote printing factory is a very mysterious enterprise. First of all, people are interested in how such an enterprise dealing with money all day long is managed. The public is also interested in the technological process of money printing. They want to know how the money printing workers turn a small piece of white paper into "money" by working step by step
China is a big money printing country, and the printing level and technology content of RMB have reached the advanced level of the world's money printing technology. China's banknote proction and circulation are among the best in the world
China has a large circulation of banknotes, and the anti-counterfeiting task of banknotes is also very arous. Therefore, it is very necessary for the public to understand the anti-counterfeiting knowledge of RMB. To let the public know about the proction process of some RMB will also be of great help to the public in identifying counterfeit currency. Because of this consideration, when the new version of RMB 20 was issued, we asked the Information Department of the general office of the people's Bank of China to interview the banknote printing factory, and they agreed
we drove to Shijiazhuang to interview Shijiazhuang banknote printing factory
interestingly, although the economic benefits of Shijiazhuang banknote printing factory are among the best in the local area, there is not even a brand at the front gate of the banknote printing factory. When asked why the party secretary didn't put up a sign, he said, "no publicity."
the first thing we visited was the paper selection department. When we entered the gate, there was a closed glass door. Several uniformed security personnel asked us to register, and then stored the bags. When everything was ready, the accompanying factory cadres took out a magnetic card and inserted it into the box at the door, and the safety door opened. The work of paper selection department is to check the quality of banknote paper. Banknote paper is a kind of special paper specially developed for banknote printing<

the reason why banknote paper is special is that besides its physical and chemical properties such as wear resistance, folding resistance, acid resistance and alkali resistance, there are also many new high-tech contents, such as safety wire, colored red and blue fiber, etc. it is also full of watermark patterns for anti-counterfeiting, The 20 yuan banknote paper is a fixed flower pattern. The workers check the quality of the paper one by one on the light box. Because there is a problem with the direction of the watermark, each paper must be arranged according to the direction of the watermark pattern, and punch holes on the side with a punch. In this link, you can't make mistakes, otherwise you will print banknotes with inverted watermarks. This kind of banknote is a waste in the banknote printing factory, but if it enters the market, it will become a valuable "treasure" in the hands of coin lovers. The reason why it is valuable is that the strict quality inspection of the banknote printing factory makes it impossible for this kind of waste to flow to the market
next, we come to the printing workshop. Several super gravure printing machines are running at high speed. Gravure printing is different from other printing in the society, because the gravure printing plate is made from the steel plate carved by the steel plate engraver of the banknote printing factory. The part with lines on the pattern is concave. When printing, the ink is filled in. When printing on the paper, the gravure printing plate is made from the steel plate carved by the steel plate engraver of the banknote printing factory, The ink of the pattern is piled up in a three-dimensional shape, which is difficult for counterfeiters to , because most of the ordinary printing in the society uses flat printing of photographic plate making. As long as the public can understand this point and touch it when using banknotes, most counterfeit banknotes can be identified
in the printing workshop, it happened that a machine was trying to print. People who know a little bit about printing all know that at the beginning of printing, they always have to go through a trial printing before they can adjust to the best state. We found that the printers piled some waste procts in a corner. I picked up one and looked at it carefully. I found that it was yellow paper, not banknote paper. I asked, "why not use banknote paper for trial printing?" The worker replied, "it's no good, because every banknote is strictly controlled in quantity, and there can't be less than one. If there is waste, even if it is crumpled into a group, we have to register and review it. There are a series of proceres. "
in the management of the banknote printing plant, the most characteristic is digital management, that is, from the paper out of the warehouse, until the finished procts are sealed and packed into the Treasury, in each link, we have to check the number, "how much is taken out, how much is returned". There is a saying here, which is called "handle must count". Digital management is an effective means of management. But after all, this is an external management constraint. In order to make people who face thousands of banknotes every day do not want to be separated, what is more important is "inner moral constraint"<
a worker in Xi'an banknote printing factory said: "these money are not money in my eyes. They are just like the procts in the hands of workers in other instries. For example, the workers in Haier washing machine factory look at their washing machines, and even the farmers look at the cabbage and tomato in the field, I can't associate my money with the commodities in the market. I can't think about how much money I can buy, such as mobile phones and cars. I can't associate my money with my salary. I have only one idea in my heart: do a good job and make no mistakes. "
as soon as I walked into the hall of the sealing workshop, my first feeling was that it was like the reading room of the university library, with semi closed workbenches arranged neatly, with stacks of 20 yuan in the hands and tables of female quality inspection workers. The bright light is pouring out like mercury, and there is a desk lamp on everyone's desk. The light is so important, because these quality inspection workers have to check the quality of each piece of RMB under the light, such as: whether the number is printed wrong, whether the color is uniform, and whether the watermark is inverted... I asked a female worker: "how many pieces do you want to see in a day?" "Tens of thousands," she replied
this kind of quality inspection work is very hard and monotonous. Just imagine that every hour, every day, every month and every year you are staring at the same number of pictures, which is very hard work
I found that in the banknote printing plant, the sealing workshop is the Department with the largest number of people in the whole plant. RMB is indeed a special proct, its quality is related to the reputation of the country. In China's banknote printing instry, RMB is known as "China's business card". The business card of a country is not allowed to make mistakes
in the sealing workshop, there are two steps to check the quality of RMB. The first step is to check the large sheets first, that is, to check the large plates with 24 RMB printed down from the printing press. At this time, the quality inspection is mainly to check whether there are quality problems on the macro level, such as whether the color is accurate, whether there are damages, whether there are missing prints... In a spacious hall, dozens of female workers have a thick pile of large pieces of RMB on the workbench in front of them
the second set of RMB five yuan front
when the large sheet is checked, the next process is to cut off the 24 pieces of RMB on the large sheet and turn them into the same size RMB as we usually use. The next step is to check the small pieces of RMB and check the small pieces of RMB. More people are needed. And it's harder
at night, we left Shijiazhuang, and every move we made in Shijiazhuang banknote printing factory was left in the computer photography system. By the way, I forgot to introce the safety measures in printing press. Another thing is that every workshop has 24 hours of no stopping photography system. Any time and place can be checked out from computer records. The process of banknote printing can be divided into four steps: research, plate making, printing and finishing
(1) research process: focusing on the anti-counterfeiting performance and artistry of banknotes, according to the requirements of the national banknote issuing agency, design the draft of banknotes
(2) plate making process: plate making plays a very important role in the anti-counterfeiting of banknotes, and plate making is an important part in the anti-counterfeiting of banknotes printing technology. The paper money plate making can be divided into manual carving and machine carving. The paper money plate making is aimed at the main drawing, pattern, flower decoration, line and text in the original design. The main picture, such as the characters and scenery on the paper money, is carved into the original mold by hand, while the characters, lines and geometric patterns are carved by machines and made into the master by photographing. After proofing the original horizontal and master, it needs to be reviewed by relevant departments before making the whole printing plate
(3) printing process: it involves the set conditioning of printing plate, paper, ink, printing press, etc. Banknotes are printed by a special banknote printing machine. Both banknotes and ink are specially made by the relevant departments authorized by the state. The purpose is to strengthen the anti-counterfeiting function of banknotes
(4) finishing process: after the banknotes are printed, they have to go through a series of work to ensure that they are correct before they can be issued and circulated. The work of this stage mainly includes: leak detection, number printing, cutting, number printing, bad ticket replacement, quantity statistics, packaging and warehousing
generally speaking, the printing process of banknotes is basically carried out according to the issued process: designing banknote map → making engraving plate → making printing plate → offset printing → concave convex printing → printing number → checking large sheet → cutting into sheet → checking sheet → counting quantity → packing and placing in box → entering warehouse< The third set of RMB one yuan back: 2. Printing methods of banknotes: lithographic printing, gravure printing, relief printing and mixed printing< (1) lithography: lithography is commonly known as offset printing. Lithography is based on the principle that oil and water repel each other. By pressing the oil-resistant and hydrophilic blank part properly, the ink pattern is transferred to the surface of the paper. The characteristic of lithography is that the pattern and plate are almost on the same plane, that is to say, the printing image is placed on the surface of the plate. Lithography includes overprint, overprint, color separation, double-sided printing, pattern printing and so on. Lithography is mainly used for large area of shading patterns on the background of banknotes or complex fine line patterns. For example, the sample of lithography printed by the Printing Bureau of the Ministry of Finance in 2004
(2) gravure printing: gravure printing is carried out by inking the pattern which is sunken under the plate plane. During printing, appropriate pressure is applied to transfer the sunken ink onto the surface of the paper, and the inked pattern is placed on the paper in a three-dimensional form. The main patterns on the banknotes are carved by hand. The lines with different thickness are carved by the sculptor, so it is very difficult to forge them. Therefore, engraving gravure printing anti-counterfeiting is very high. The first set of engraving gravure banknotes in China was printed by the printing office of Daqing branch in 1910. The engraving part of the banknotes was completed by Haiqu, an American sculptor employed by the Qing government. Engraving gravure is mainly used in the main patterns of banknotes. And many countries in the world are also developing

The work of this stage mainly includes: leak detection, number printing, cutting, number printing, bad ticket replacement, quantity statistics, packaging and warehousing
generally speaking, the printing process of banknotes is basically carried out according to the issued process: designing banknote map → making engraving plate → making printing plate → offset printing → concave convex printing → printing number → checking large sheet → cutting into sheet → checking sheet → counting quantity → packing and placing in box → entering warehouse< The third set of RMB one yuan back: 2. Printing methods of banknotes: lithographic printing, gravure printing, relief printing and mixed printing< (1) lithography: lithography is commonly known as offset printing. Lithography is based on the principle that oil and water repel each other. By pressing the oil-resistant and hydrophilic blank part properly, the ink pattern is transferred to the surface of the paper. The characteristic of lithography is that the pattern and plate are almost on the same plane, that is to say, the printing image is placed on the surface of the plate. Lithography includes overprint, overprint, color separation, double-sided printing, pattern printing and so on. Lithography is mainly used for large area of shading patterns on the background of banknotes or complex fine line patterns. For example, the sample of lithography printed by the Printing Bureau of the Ministry of Finance in 2004
(2) gravure printing: gravure printing is carried out by inking the pattern which is sunken under the plate plane. During printing, appropriate pressure is applied to transfer the sunken ink onto the surface of the paper, and the inked pattern is placed on the paper in a three-dimensional form. The main patterns on the banknotes are carved by hand. The lines with different thickness are carved by the sculptor, so it is very difficult to forge them. Therefore, engraving gravure printing anti-counterfeiting is very high. The first set of engraving gravure banknotes in China was printed by the printing office of Daqing branch in 1910. The engraving part of the banknotes was completed by Haiqu, an American sculptor employed by the Qing government. Engraving gravure is mainly used in the main patterns of banknotes. And many countries in the world are also developing

With the development of the times, people's living standards are becoming higher and higher, and the role of money is becoming more and more important. Everyone wants to have a high salary. The higher the salary of others is, the stronger his ability is. At the same time, it can bring him a better material life, and he doesn't need to worry about money any more. Except for the high salary, everything will become more and more smooth. Pay means that their living conditions are getting better and better, material needs are more and more easy to meet. High wages can also bring more opportunities to themselves. With a high salary, you don't have to worry about finding your girlfriend any more. Therefore, without a high salary, Baili will do no harm. What's the feeling of earning 10000 yuan a day? Let me explain to you slowly:
if you earn 10000 yuan a day, you can meet your daily expenses and even have a lot of surplus. If you earn 10000 yuan a day, you can eat delicacies every day and never feel the pain of no money. No longer because of mortgage car loan and feel pressure, life will be relatively more relaxed, rich life is often very happy
it's like a dream to earn 10000 yuan a day. It's hard for us ordinary people to imagine. I hope everyone can earn 10000 yuan a day
7. Some very similar one yuan coins are formed twice, so the front and back patterns are reversed (seen in the news)
the following is a friendly tip from a bank. First, the manufacturing process is poor, the nickel coating is thin, and it is easy to rust and rot. Real coins are generally not rusty. If rusty coins are found, they are likely to be counterfeit coins< Second, the grain of wheat ear in the national emblem is fuzzy, the ribbon level is poor, and the fine stripe is not clear
Third, the five pointed star in the national emblem has poor three-dimensional sense, the angle of the five pointed star is long and short, and the top is smooth
4. The strokes of Chinese characters and Pinyin letters on the front are thick, the petals and veins of chrysanthemum on the back are fuzzy, and the flower core is fuzzy
fifthly, fake coins are lighter than real coins.

9. When we do java development, we usually encounter the problem of how to protect our code. Java language is based on the JVM, so it is very easy to decompile the class file. Suppose we make a web program and publish it to customers. In fact, it is very easy for customers to decompile our source code, including all SRC files and JSP files, etc
in fact, there are several ways to protect our source code: 1. Use code obfuscator; 2. Overload classloader of application server
for the first method, there are many open source tools available, and I think the best one is Proguard. Proguard is mainly easy to use and learn. And it also provides a lot of functions. The following is my personal experience in using
(1) Download Proguard tool from the Internet. Proguard tool mainly includes several jar files, some examples and download address http://proguard.sourceforge.net/
(2) add several jar files to the classpath. Of course, you can not add it, but when doing obfuscation, you must specify classpath to make sure that you can access this class in the process of obfuscation
(3) write a configuration file, mainly some parameters of obfuscator. For example, here is an example
- injars platform. Jar
- outjars platform_ out.jar
-libraryjars < java.home>/ lib/rt.jar
-libraryjars ibatis-common-2.jar
-libraryjars ibatis--2.jar
-libraryjars ibatis-sqlmap-2.jar
-libraryjars junit-3.8.1.jar
-libraryjars d:/j2ee.jar
-libraryjars struts.jar
-libraryjars commons-lang.jar
-libraryjars D:/0working/coreproject/byislib/jasperreports-0.6.1.jar
-libraryjars commons-beanutils.jar
-printmapping proguard.map
-overloadaggressively
-defaultpackage '&# 39; < br />-allowaccessmodification
-dontoptimize
-keep public class *
{
public protected *;
}
- keep public class org. * *
- keep public class it. * *
please refer to Proguard document for the meaning of each parameter. This document is very detailed and easy to start with
OK. This is the end of code obfuscation. Open the generated jar package and you can see that there are many more class files such as a, B and C. It shows that the confusion result has been successful. Delete the original jar and run the confused jar package. Everything is normal<
common problems: in the process of using, I have encountered several problems, and it took me a long time to solve them at the beginning.
A. memory overflow exception: the main reason is that Proguard eats a lot of memory when doing obfuscation, so it can increase memory when running obfuscator, For example, Java - mx512m.....
B. stack overflow exception: when Proguard confuses, it optimizes some code, and if it encounters some relatively complex methods, it may throw this exception. The solution is to increase the configuration parameter dontoptimize, as shown in the above configuration example
for the second method, the principle of overload server classloader is as follows. First, we encrypt the class file by some algorithm; Then write our own classloader and replace the server's classloader. In this way, we can read the class file, anti encrypt it into the correct class through our own algorithm, and then load it again. This method has not been applied yet. I am studying these days, and I will summarize some new achievements here
Proguard is an open source project http://proguard.sourceforge.net/ The latest version is 3.3.2. Loading the obfuscator is very simple. You just need to unzip proguard3.3.2.zip, and then use J2ME - & gt; Packing-> Select the installation directory of Proguard from the obfuscation tab. As shown in the figure below, you can configure the class name that needs to be preserved in the process of obfuscation. The name of MIDlet class must be preserved so that the Java runtime environment (JRE) of the device can find the entry point of execution< br /> http://images.csdn.net/20050726/image027.jpg , it's about the above pic.

Proguard is a free Java class file compressor, optimizer and obfuscator. It can find and delete useless classes, fields, methods and attribute values. It also optimizes bytecode and removes useless instructions. Finally, it uses simple meaningless names to rename your class name, field name, and method name. After the above operation, the jar file will become smaller and difficult to reverse engineer. It is mentioned here that the main functions of Proguard are compression, optimization and obfuscation. Now I will introce these concepts first, and then introce the basic usage of Proguard
l what is compression:
java source code (. Java file) is usually compiled into bytecode (. Class file). A complete program or library is usually compressed and published as a Java document (. Jar file). Bytecode is simpler than Java source file, but it still contains a lot of useless code, especially when it is a program library. Proguard's compressor operation can analyze bytecode and delete useless classes, fields and methods. The program only retains the functional equivalence, including the information needed for exception stack description<
l what is confusion:
generally, compiled bytecode still contains a lot of debugging information: source file name, line number, field name, method name, parameter name, variable name, etc. This information makes it easy to decompile and reverse engineer to get a complete program. Sometimes, it's disgusting. For example, an obfuscator like Proguard can delete the debugging information and replace all names with meaningless character sequences, making it difficult to reverse engineer, and further recing the code for free. Except for the class name, method name and line number required by the exception stack information, the program only retains functional equivalence. From the above understanding, you should understand why confusion is needed.
