Donglin International Group is not a pyramid scheme, but a Ponzi scheme. Donglin International Group is one of 232 illegal fund scams announced on October 18. Donglin international claims to be regulated by the NFA, India's financial regulator. Donglin international distinguishes the so-called capital markets such as split, mutual aid, virtual currency, dividend, binary options and micro trading, claiming that all the income comes from the foreign exchange market, with monthly income as high as 15% to 20% (floating) and being open and transparent. This kind of publicity is estimated to be sufficient for the fixed conditions of illegal fund-raising

3. It is suggested to stay away from these projects, which have been named by four ministries and commissions<
the CBRC, the Ministry of instry and information technology, the people's Bank of China and the State Administration for Instry and Commerce suggest that in recent years, in the name of "financial mutual assistance", the behavior of promising high returns and luring the public to invest funds has appeared in many places in China. Its main characteristics include: 1
first, there are many names. Common are: "XX financial mutual aid community", "XX financial mutual aid platform", "XX financial mutual aid financing", "XX charity financial mutual aid platform", "XX financial mutual aid investment", "XX mutual aid community", "XX wealth mutual aid platform", etc< Second, it develops rapidly. Relying on the Internet, through the website, blog, wechat, QQ and other platforms, the publicity has a wide range
thirdly, it is confusing. Under the banner of "overseas celebrities", some claim to "destroy the unfair world financial system, break the control of financiers, and create a community for ordinary people" as the goal. Through the establishment of the so-called "fair, just, mutually beneficial and honest financial platform for people to help others", the public can get more help by subsidizing others. At the same time, he falsely claimed that "after market test, he has been mature in many countries for many years, and has hundreds of millions of members in the world" and so on
4. Strong incement. It claims that the investment threshold is low, the cycle is short and the income is high. For example, after free registration, the investment of RMB 60000-60000 can be withdrawn after 15 days, with daily income of 1%, monthly income of 30%, annual income of 23 times, and no handling charge. In addition, if participants develop others to join, they can also get extra income such as recommendation Award (10% of offline investment) and Management Award (the corresponding proportion is determined according to the membership level). There is no upper limit for development personnel and no upper limit for rebate< 5. Strong concealment. Most of them are controlled remotely by overseas personnel, and the investment funds are often transferred through personal bank accounts or through third-party payment platforms
this kind of operation mode violates the law of value, and it is difficult to maintain the capital operation for a long time. Once the capital chain breaks, investors will face serious losses. The general public is requested to raise their awareness of risks, invest rationally and prudently, and prevent their interests from being damaged. At the same time, we can actively report to the relevant departments the clues we have learned about crimes
bitcoin home has also reported a number of similar virtual money pyramid schemes. You can check them out.

Hershey, Alfred day, American microbiologist. Born on December 4, 1908 in ovoso, Michigan. Hershey received a doctorate from Michigan State University in 1934, then taught at the University of Washington. After 1950, Hershey transferred to Cold Spring Harbor, New York, and retired in 1975. His academic interest is the study of bacteriophages. In 1945, he showed that there were spontaneous mutations in bacteriophages and the bacterial cells they preyed on, which was the same result that Luria made independently at the same time. In 1946, he proved that the genetic material of different viruses can spontaneously combine to proce mutation effect, which is the same as the result of Delbruck's independent proof. In 1952, he proved that it was the nucleic acid of bacteriophage that entered the bacterial cell, which showed that it was the nucleic acid that carried the genetic information, not the protein related to it. This conclusion makes Watson and Crick's discovery of nucleic acid replication more revolutionary the next year.

8. I think it will be a lot. I've sorted it out for you. You can have a look at it:
Edison:
Edison's story
Edison only went to primary school for three months in his life. His knowledge came from his mother's teaching and self-study. His success should be attributed to his mother's understanding and patient teaching since childhood, which made Edison, who was originally regarded as an incompetent child, become a world-famous "king of invention" when he grew up
Edison was curious about many things since he was a child, and he liked to experiment with them himself until he understood the truth. When he grew up, he devoted himself to research and invention according to his own interests. He set up a laboratory in New Jersey and invented more than 2000 kinds of things in his life, such as electric lamp, telegraph, phonograph, video camera, magnetic separator, crusher and so on. Edison's strong research spirit made him make great contribution to the improvement of human life style
"waste, the biggest waste is to waste time." Edison often said to his assistant“ Life is too short. Think more and do more with less time. "
one day, Edison was working in the laboratory. He handed his assistant an empty glass bulb without a light port and said, "you measure the capacity of the bulb." He bowed his head to work again
after a long time, he asked, "what's the capacity?" He didn't hear the answer. He turned his head and saw his assistant measuring the perimeter and inclination of the bulb with a tape measure. He took the measured number and put it on the table to calculate. He said, "time, time, how do you spend so much time?" Edison came over, picked up the empty light bulb, filled it with water, handed it to his assistant, and said, "pour the water in the measuring glass, and tell me its capacity right away."
the assistant immediately read out the number
Edison said, "what an easy way to measure. It's accurate and time-saving. Why can't you think of it? Is it not a waste of time? "
the assistant blushed
Edison murmured: "life is too short, too short. Save time and do more things!"< Before he became famous, Edison was a poor worker. Once, his old friend met him in the street and said with concern, "look, this overcoat on you is not in good condition. You should replace it with a new one."
"do you need it? No one knows me in New York Edison answered with indifference
a few years later, Eddie has become a great inventor< One day, Edison met his friend on the street of New York“ "Oh," exclaimed the friend, "Why are you still wearing this old coat? This time, you need a new one anyway
"do you need it? Everyone here already knows me. " Edison still answered with indifference<
Ronnie Thompson:
Iceman Ronnie Thompson
when the vast majority of geologists focus on the earth's north and south poles, Ronnie Thompson focuses on the field of tropical glaciers, which has long been ignored by the academic community. The earth we live in is getting warmer and warmer. Ronnie Thompson, an American glaciologist who has been working on the study of tropical glaciers for many years, is trying to climb more peaks before the snow melts and collect valuable information about the earth's climate change
a few years ago, Ronnie Thompson, an ice geographer at Ohio State University, stood on the top of Kilimanjaro Mountain in East Africa and carefully observed a cylindrical ice core handed over by his colleagues. With nearly a quarter of a century's weathered professional vision, he saw at a glance that the glass like smooth ice core surface was actually full of small eyes. This is not a small bubble formed by the occasional infiltration of air, but a groove mark left by the flow of snow water after the melting of ice and snow. It's not an optimistic signal
the small eyes on the surface of the ice core confirm Thompson's conjecture: the temperature of Kilimanjaro Mountain in East Africa is rising rapidly, and the layers of snow covering the mountain top may melt away in 15 years. If so, Mount Kilimanjaro, once described by Ernest Hemingway as "great, sublime and incredibly white", will eventually become a fragment in people's memory. As a precaution, Thompson and his colleagues managed to take these ice core samples back to Ohio State University and put them in their ultra-low temperature polar freezer together with geological samples from a previous tropical Alpine expedition
in the next five years, Thompson discovered many more valuable things from these various geological collections. Like tree rings, the aged ice cores on the mountains have been playing the role of a faithful recorder of nature for many years, recording the climate change information such as temperature and precipitation over the centuries for the region. Thanks to Thompson's "geological decryption" work, these valuable materials collected in the nature library will not be lost after the melting of ice and snow
it is gratifying that Thompson has rescued and cracked many geological records. For example, in 1983, he reconstructed the climate change process of Peru from wet to dry in the past 1500 years from the samples collected from quelcaya ice peak in southern Peru, which can be used as a natural annotation of the rise and fall of civilization in the region in the past 1500 years. In 1987, he successfully interpreted the geological evolution history of the Qinghai Tibet Plateau in China for nearly 40000 years, and then in 1992, he successfully interpreted the evolution history of the ancient ice layer in China for nearly 760000 years. In addition, Thompson proved forcefully that from the Andes in southern America to the circumtropical glaciers in the Himalayas in Central Asia, the climate 20000 years ago was much colder than scientists now think<
Pasteur:
Pasteur's exploration
Louis Pasteur, French microbiologist, chemist and founder of modern microbiology. Just as Newton opened up classical mechanics, Pasteur opened up the field of Microbiology, and he was also a scientific giant
Pasteur is one of the most successful scientists in the 19th century, who has carried out a number of exploratory researches and made great achievements in his life. He spent his whole life proving three scientific problems: (1) every kind of fermentation is e to the development of a kind of micro bacteria. The French chemist found that heating can kill the annoying microorganisms that make beer bitter. Soon, pasteurization was applied to all kinds of food and drink 2) Every infectious disease is the development of a microbe in the organism: Pasteur saved the French silk instry by discovering and eradicating a bacterium that invades silkworm eggs 3) The micro bacteria of infectious diseases, under special cultivation, can rece their virulence and turn them from bacteria into vaccine for disease prevention. He realized that many diseases were caused by microorganisms, so he established the theory of bacteria
Louis Pasteur is praised as "the most perfect man to enter the kingdom of science". He is not only a genius in theory, but also a man good at solving practical problems. In 1843, he published two papers - "study of double crystal phenomenon" and "crystalline morphology", which initiated the study of optical properties of matter. From 1856 to 1860, he put forward a new theory of fermentation essence based on microbial metabolic activities. The "record of lactic acid fermentation" published in 1857 is a classic paper recognized by the microbiological circle. After 1880, many kinds of vaccines, such as chicken cholera vaccine and rabies vaccine, were successfully developed. Their theories and immunization methods caused great changes in medical practice. In addition, Pasteur's work has successfully saved the wine making, sericulture and animal husbandry in France
Pasteur is considered to be the most important and outstanding person in the history of medicine. Pasteur's contribution involves several disciplines, but his reputation focuses on defending and supporting the germ theory and developing vaccination against disease
Pasteur was not the first discoverer of the pathogen. Before him, kirula, bauhenri and others have put forward similar assumptions. However, Pasteur not only enthusiastically and bravely put forward the theory of bacteria, but also proved the correctness of his theory through a large number of experiments, which convinced the scientific community. This is his main contribution
obviously, the cause of the disease is bacteria, so it is obvious that only by preventing bacteria from entering the human body can we avoid the disease. Therefore, Pasteur stressed that doctors should use disinfection. Joseph sinster, who proposed to the world the use of disinfection in surgery, was influenced by Pasteur. Toxic bacteria enter human body through food and drink. Pasteur developed a method of sterilization in beverages, later known as pasteurization (heat sterilization)
at the age of 50, Buster focused on the malignant carbuncle mark. It is an infectious disease that endangers livestock and other animals, including human beings; Pasteur proved that it was caused by a special bacterium. He injected the animals with attenuated bacilli malignant carbuncle
in 1881, Pasteur improved the method of recing the virulence of pathogenic microorganisms. He observed animals that had suffered from an infectious disease and recovered, and later became immune to the disease. According to these results, sheep and chickens were immunized with attenuated anthrax and chicken cholera respectively. This method has greatly stimulated the enthusiasm of scientists. People know that many infectious diseases can be avoided by this method
in 1882, basoud was selected as an academician of the French Academy. In the same year, he began to study rabies, proving that the pathogen existed in the saliva and nervous system of the infected animals, and made a live salt poison vaccine, which successfully helped people gain immunity against the disease. According to the Pasteur immunization method, medical scientists have created vaccines to prevent several kinds of dangerous diseases, successfully eliminating the threat of typhoid fever, poliomyelitis and other diseases< When it comes to rabies, people naturally think of Pasteur's well-known story. Pasteur did not know that rabies was a viral disease in the era of bacterial theory, but he knew from scientific practice that infectious substances would rece their toxicity after repeated passage and drying. He injected the mella oblongata extract containing the pathogenic rabies into rabbits for many times, and then injected the attenuated liquid into dogs. After that, dogs could resist the infection of rabies virus with normal intensity. In 1885, a 9-year-old boy who was badly bitten by a mad dog was sent to Pasteur for rescue. Pasteur hesitated for a while, then injected the child with the above-mentioned extract with very low toxicity, and then graally injected it with the more toxic extract. Pasteur's idea is to make him resistant before the incubation period of rabies has passed. As a result, Pasteur succeeded and the child was saved. In 1886, another 15-year-old shepherd who was seriously bitten while rescuing a companion attacked by a mad dog, zhupiye, was rescued. Now the sculpture describing the young man's brave deeds and Pasteur's great achievements is located outside the Pasteur Institute in Paris. Pasteur invented the rabies vaccine in 1889. He also pointed out that the pathogen was a "filterable superorganism" that could pass through a bacterial filter
Pasteur himself is the best

Ronnie Thompson:
Iceman Ronnie Thompson
when the vast majority of geologists focus on the earth's north and south poles, Ronnie Thompson focuses on the field of tropical glaciers, which has long been ignored by the academic community. The earth we live in is getting warmer and warmer. Ronnie Thompson, an American glaciologist who has been working on the study of tropical glaciers for many years, is trying to climb more peaks before the snow melts and collect valuable information about the earth's climate change
a few years ago, Ronnie Thompson, an ice geographer at Ohio State University, stood on the top of Kilimanjaro Mountain in East Africa and carefully observed a cylindrical ice core handed over by his colleagues. With nearly a quarter of a century's weathered professional vision, he saw at a glance that the glass like smooth ice core surface was actually full of small eyes. This is not a small bubble formed by the occasional infiltration of air, but a groove mark left by the flow of snow water after the melting of ice and snow. It's not an optimistic signal
the small eyes on the surface of the ice core confirm Thompson's conjecture: the temperature of Kilimanjaro Mountain in East Africa is rising rapidly, and the layers of snow covering the mountain top may melt away in 15 years. If so, Mount Kilimanjaro, once described by Ernest Hemingway as "great, sublime and incredibly white", will eventually become a fragment in people's memory. As a precaution, Thompson and his colleagues managed to take these ice core samples back to Ohio State University and put them in their ultra-low temperature polar freezer together with geological samples from a previous tropical Alpine expedition
in the next five years, Thompson discovered many more valuable things from these various geological collections. Like tree rings, the aged ice cores on the mountains have been playing the role of a faithful recorder of nature for many years, recording the climate change information such as temperature and precipitation over the centuries for the region. Thanks to Thompson's "geological decryption" work, these valuable materials collected in the nature library will not be lost after the melting of ice and snow
it is gratifying that Thompson has rescued and cracked many geological records. For example, in 1983, he reconstructed the climate change process of Peru from wet to dry in the past 1500 years from the samples collected from quelcaya ice peak in southern Peru, which can be used as a natural annotation of the rise and fall of civilization in the region in the past 1500 years. In 1987, he successfully interpreted the geological evolution history of the Qinghai Tibet Plateau in China for nearly 40000 years, and then in 1992, he successfully interpreted the evolution history of the ancient ice layer in China for nearly 760000 years. In addition, Thompson proved forcefully that from the Andes in southern America to the circumtropical glaciers in the Himalayas in Central Asia, the climate 20000 years ago was much colder than scientists now think<
Pasteur:
Pasteur's exploration
Louis Pasteur, French microbiologist, chemist and founder of modern microbiology. Just as Newton opened up classical mechanics, Pasteur opened up the field of Microbiology, and he was also a scientific giant
Pasteur is one of the most successful scientists in the 19th century, who has carried out a number of exploratory researches and made great achievements in his life. He spent his whole life proving three scientific problems: (1) every kind of fermentation is e to the development of a kind of micro bacteria. The French chemist found that heating can kill the annoying microorganisms that make beer bitter. Soon, pasteurization was applied to all kinds of food and drink 2) Every infectious disease is the development of a microbe in the organism: Pasteur saved the French silk instry by discovering and eradicating a bacterium that invades silkworm eggs 3) The micro bacteria of infectious diseases, under special cultivation, can rece their virulence and turn them from bacteria into vaccine for disease prevention. He realized that many diseases were caused by microorganisms, so he established the theory of bacteria
Louis Pasteur is praised as "the most perfect man to enter the kingdom of science". He is not only a genius in theory, but also a man good at solving practical problems. In 1843, he published two papers - "study of double crystal phenomenon" and "crystalline morphology", which initiated the study of optical properties of matter. From 1856 to 1860, he put forward a new theory of fermentation essence based on microbial metabolic activities. The "record of lactic acid fermentation" published in 1857 is a classic paper recognized by the microbiological circle. After 1880, many kinds of vaccines, such as chicken cholera vaccine and rabies vaccine, were successfully developed. Their theories and immunization methods caused great changes in medical practice. In addition, Pasteur's work has successfully saved the wine making, sericulture and animal husbandry in France
Pasteur is considered to be the most important and outstanding person in the history of medicine. Pasteur's contribution involves several disciplines, but his reputation focuses on defending and supporting the germ theory and developing vaccination against disease
Pasteur was not the first discoverer of the pathogen. Before him, kirula, bauhenri and others have put forward similar assumptions. However, Pasteur not only enthusiastically and bravely put forward the theory of bacteria, but also proved the correctness of his theory through a large number of experiments, which convinced the scientific community. This is his main contribution
obviously, the cause of the disease is bacteria, so it is obvious that only by preventing bacteria from entering the human body can we avoid the disease. Therefore, Pasteur stressed that doctors should use disinfection. Joseph sinster, who proposed to the world the use of disinfection in surgery, was influenced by Pasteur. Toxic bacteria enter human body through food and drink. Pasteur developed a method of sterilization in beverages, later known as pasteurization (heat sterilization)
at the age of 50, Buster focused on the malignant carbuncle mark. It is an infectious disease that endangers livestock and other animals, including human beings; Pasteur proved that it was caused by a special bacterium. He injected the animals with attenuated bacilli malignant carbuncle
in 1881, Pasteur improved the method of recing the virulence of pathogenic microorganisms. He observed animals that had suffered from an infectious disease and recovered, and later became immune to the disease. According to these results, sheep and chickens were immunized with attenuated anthrax and chicken cholera respectively. This method has greatly stimulated the enthusiasm of scientists. People know that many infectious diseases can be avoided by this method
in 1882, basoud was selected as an academician of the French Academy. In the same year, he began to study rabies, proving that the pathogen existed in the saliva and nervous system of the infected animals, and made a live salt poison vaccine, which successfully helped people gain immunity against the disease. According to the Pasteur immunization method, medical scientists have created vaccines to prevent several kinds of dangerous diseases, successfully eliminating the threat of typhoid fever, poliomyelitis and other diseases< When it comes to rabies, people naturally think of Pasteur's well-known story. Pasteur did not know that rabies was a viral disease in the era of bacterial theory, but he knew from scientific practice that infectious substances would rece their toxicity after repeated passage and drying. He injected the mella oblongata extract containing the pathogenic rabies into rabbits for many times, and then injected the attenuated liquid into dogs. After that, dogs could resist the infection of rabies virus with normal intensity. In 1885, a 9-year-old boy who was badly bitten by a mad dog was sent to Pasteur for rescue. Pasteur hesitated for a while, then injected the child with the above-mentioned extract with very low toxicity, and then graally injected it with the more toxic extract. Pasteur's idea is to make him resistant before the incubation period of rabies has passed. As a result, Pasteur succeeded and the child was saved. In 1886, another 15-year-old shepherd who was seriously bitten while rescuing a companion attacked by a mad dog, zhupiye, was rescued. Now the sculpture describing the young man's brave deeds and Pasteur's great achievements is located outside the Pasteur Institute in Paris. Pasteur invented the rabies vaccine in 1889. He also pointed out that the pathogen was a "filterable superorganism" that could pass through a bacterial filter
Pasteur himself is the best
9. Edison
Edison only went to primary school for three months in his life. His knowledge came from his mother's teaching and self-study. His success should be attributed to his mother's understanding and patient teaching since childhood, which made Edison, who was originally regarded as an incompetent child, become a world-famous "king of invention" when he grew up
Edison was curious about many things since he was a child, and he liked to experiment with them himself until he understood the truth. When he grew up, he devoted himself to research and invention according to his own interests. He set up a laboratory in New Jersey and invented more than 2000 kinds of things in his life, such as electric lamp, telegraph, phonograph, video camera, magnetic separator, crusher and so on. Edison's strong research spirit made him make great contribution to the improvement of human life style
"waste, the biggest waste is to waste time." Edison often said to his assistant“ Life is too short. Think more and do more with less time. "
one day, Edison was working in the laboratory. He handed his assistant an empty glass bulb without a light port and said, "you measure the capacity of the bulb." He bowed his head to work again
after a long time, he asked, "what's the capacity?" He didn't hear the answer. He turned his head and saw his assistant measuring the perimeter and inclination of the bulb with a tape measure. He took the measured number and put it on the table to calculate. He said, "time, time, how do you spend so much time?" Edison came over, picked up the empty light bulb, filled it with water, handed it to his assistant, and said, "pour the water in the measuring glass, and tell me its capacity right away."
the assistant immediately read out the number
Edison said, "what an easy way to measure. It's accurate and time-saving. Why can't you think of it? Is it not a waste of time? "
the assistant blushed
Edison murmured: "life is too short, too short. Save time and do more things!"< Before he became famous, Edison was a poor worker. Once, his old friend met him in the street and said with concern, "look, this overcoat on you is not in good condition. You should replace it with a new one."
"do you need it? No one knows me in New York Edison answered with indifference

"do you need it? Everyone here already knows me. " Edison still answered with indifference
nowadays, the telephone has entered thousands of households. Do you know who invented the telephone
bell is the inventor of the telephone. He was born in England in 1847. When he was young, he was engaged in teaching for the deaf with his father. He wanted to make a machine for the deaf to see sound with their eyes
in 1873, bell, who became a professor at Boston University in the United States, began to study the device for transmitting many telegrams on the same line - multiplex telegram, and germinated the idea of using electric current to transmit people's voice to distant places, so that people far away can talk face to face. So bell began to study the telephone
on June 2, 1875, bell and his assistant Watson were experimenting with the multiplex telegraph in two rooms respectively. An accidental accident inspired bell. A spring on the telegraph in Watson's room stuck to the magnet. When Watson opened the spring, it vibrated. At the same time, bell was surprised to find that the spring on the telegraph in his room vibrated and made a sound. It was the electric current that carried the vibration from one room to another. Bell's idea suddenly opened up, and he thought: if a person talks to a piece of iron, the sound will cause the iron to vibrate; If an electromagnet is placed behind the iron sheet, the vibration of the iron sheet is bound to proce large and small current in the electromagnet coil. This fluctuating current is transmitted to the distance along the wire, and the same vibration and sound will not occur on similar devices in the distance? So the sound goes down the wire into the distance. Isn't this the phone of my dreams
bell and Watson made the telephone according to the new idea. In one experiment, a drop of sulfuric acid splashed on Bell's leg, causing him to cry: "Mr. Watson, I need you. Please come to me!" This sentence from the telephone through the wire to Watson's ears, the phone succeeded! On March 7, 1876, bell became the patentee of the invention of the telephone
bell has obtained 18 patents in his life and 12 patents in cooperation with others. He envisioned burying the telephone line in the ground, or hanging it in the air, and connecting it to houses, villages, factories... So that the telephone can be directly connected anywhere. Today, Bell's vision has long been a reality< br />

the story of Edison.
Edison only went to primary school for three months in his life. His knowledge came from his mother's teaching and self-study. His success should be attributed to his mother's understanding and patient teaching since childhood, which made Edison, who was originally regarded as an incompetent child, become a world-famous "king of invention" when he grew up
Edison was curious about many things since he was a child, and he liked to experiment with them himself until he understood the truth. When he grew up, he devoted himself to research and invention according to his own interests. He set up a laboratory in New Jersey and invented more than 2000 kinds of things in his life, such as electric lamp, telegraph, phonograph, video camera, magnetic separator, crusher and so on. Edison's strong research spirit made him make great contribution to the improvement of human life style
"waste, the biggest waste is to waste time." Edison often said to his assistant“ Life is too short. Think more and do more with less time. "
one day, Edison was working in the laboratory. He handed his assistant an empty glass bulb without a light port and said, "you measure the capacity of the bulb." He bowed his head to work again
after a long time, he asked, "what's the capacity?" He didn't hear the answer. He turned his head and saw his assistant measuring the perimeter and inclination of the bulb with a tape measure. He took the measured number and put it on the table to calculate. He said, "time, time, how do you spend so much time?" Edison came over, picked up the empty light bulb, filled it with water, handed it to his assistant, and said, "pour the water in the measuring glass, and tell me its capacity right away."
the assistant immediately read out the number
Edison said, "what an easy way to measure. It's accurate and time-saving. Why can't you think of it? Is it not a waste of time? "
the assistant blushed
Edison murmured: "life is too short, too short. Save time and do more things!"< Before he became famous, Edison was a poor worker. Once, his old friend met him in the street and said with concern, "look, this overcoat on you is not in good condition. You should replace it with a new one."
"do you need it? No one knows me in New York Edison answered with indifference
a few years later, Eddie has become a great inventor< One day, Edison met his friend on the street of New York“ "Oh," exclaimed the friend, "Why are you still wearing this old coat? This time, you need a new one anyway
"do you need it? Everyone here already knows me. " Edison still answered with indifference< br />
