Chapter 2 Chapter Two Two Secret Telegrams from the Japanese Army

At the beginning of July in the twenty-sixth year of the Republic of China (1937), the ancient city of Nanjing looked particularly depressed under the shroud of hazy sunlight.The ever-changing summer has ushered in layers of dark clouds, gradually blocking the afterglow of the setting sun, which makes people feel particularly dull.The sky was getting darker and darker, and a sharp cold wind was blowing, as if it was going to rain.There are many guard posts on the street, military police are patrolling the streets interspersedly, and few pedestrians and vehicles are moving within the restricted range.The ancient city during the war period is under the first-level martial law, which is particularly tense.

At this time, a luxurious Chevrolet car drove out from No. 53 Ji'e Lane, and the car drove quickly on the street.When the military police along the way saw the military license plates and special signs on the car, they all stood at attention and saluted.The car slowly turned a corner, entered the silent Si Tiao Alley, and stopped in front of a white building.The front of this building was full of guards with live ammunition, and the vigilance was even stricter, revealing a murderous look in the solemnity.This is the headquarters of the famous and frightening Secret Service Fuxing Agency.The front door of the Chevrolet was opened, and a bodyguard stepped out, quickly opened the rear door and put his hand over the top of the door.Immediately, a senior military officer in his thirties stepped out of the car. This military officer was Dai Li, the most mysterious figure in the Republic of China period, and the director of the Second Division of the Bureau of Investigation and Statistics of the Military Commission (that is, the old military system).After Dai Li got out of the car, the guard officer Jia Jinnan closed the door and the driver drove away.

Accompanied by Jia Jinnan, Dai Li quickly entered the Military Control Bureau. Every time he passed by, all the internal agents stood at attention to show respect for him, and continued to work after he left.He was highly valued because of his dual identity as a student of the Whampoa Military Academy and the principal of Chiang Kai-shek's fellow Zhejiang, and enjoyed a high reputation in the Kuomintang's military and political circles. As soon as Dai Li entered Room A (his office), Yang Jirong, the head of the Intelligence Section, rushed over and stood at attention, "Reporting to the office, there is an urgent call."

"Read." Dai Li sat down at the desk. Yang Jirong took out a telegram from the folder with "Report C" and read: "Chu Zuo Junjian: According to investigations, Japanese super high-level spies will implement a conspiracy plan code-named 'Flying Snow' in Shanghai. Detailed investigation. According to the analysis of all the comrades on this site, Ritec will telegraph the contents to Shanghai Ritec in the near future. Please knock at No. KH6 of Northeast Station.” Dai Li sighed, frowned, and leaned his head on the sofa.Yang Jirong asked carefully: "Virgin, what should we do?" Dai Li asked back: "What's your opinion?" "This..." Yang Jirong showed a look of no opinion.

At this time, another person hurried in. This person had a Chinese character face, and his face was full of oil. He was Dai Li's personal secretary, Mao Renfeng.Mao Renfeng stepped forward and handed over a document, and reported: "President, this is a telegram that we detected and copied from Rite Radio Station from the northeast to Shanghai." Dai Li looked at the telegram carefully. Except for the translated Chinese at the beginning, the rest of the telegram is all Arabic numerals: Secret No. 16008 Issued by: Kwantung Army Intelligence Department Attention: Shanghai 206 Intelligence Room

"How do you do your work? Where's the translator? Why did you send over a code set that hasn't been translated yet!" Seeing his subordinate make such a huge mistake, Dai Li couldn't help being furious. "Don't be angry, Virgo, this is not some code group, but the content that has been translated. This is a secret message." Mao Renfeng explained carefully. These Arabic numerals are indeed not codes. If they are translated according to the universal codes, they become: 1532 (Cuo) 5115 (Cong) 4214 (瞀) 3162 (汧) 5451 (Guan) 9931 (Knowing the result) 4221 (Concealment) 1126 (夤) 1202 (Yao) 7115 (Chen) 1711 (Zeng) 1208 (unknown result) 2738 (Zhi) 2821 (unknown result) 4204 (sleep) 4161 (phase), the Chinese characters corresponding to the following numbers are also of this type, Can't compose anything of value at all.

These are obviously not the real content of the telegram.There are two types of telegraph codes and passwords.Although civilian telegrams are all in clear codes, the "code" must be translated into text by "translation" personnel.It is true that some people who have been engaged in telegraph work for many years can read the text when they see the code, but first, they are very few, and second, they are only suitable for plain codes.Military telegrams all use codes without exception.Passwords must be translated by translators.Generally speaking, people who send and receive telegrams only see the numbers and don't know the content, so they need to translate it against the code book, but it is limited to the code communication between their own personnel.As for the intercepted enemy radio code telegrams, cryptographic experts are needed to decipher, but it is entirely possible that they cannot be deciphered, and it is even more trivial to decipher only a telegram.Deciphering codes is "desk work".The process of deciphering the cipher code is first of all to copy the telegram, that is, to copy the enemy's telegram from the telegram receiver. Generally, many copies are required (the more the number, the more similarities can be found, and the easier it is to decipher).Then sit down and compare, analyze, and ponder over and over again, and if necessary, pass calculations to have the possibility of successful deciphering.

Dai Li thought for a moment, then couldn't help shaking his head, "It's a digital code." Mao Renfeng said: "At present, it can only be translated into this." Dai Li ordered: "Chen Shixian, chief of the speed transmission operation section, and Yang Zhenyi, director of the radio station. , Telecommunications Section Chief Wei Daming, Encryption Section Chief Liu Jie, Encryption Specialist Luo Junmin, and Liu Jianru came to the room for a meeting, and you two also came together." The two said in unison: "Yes." In the middle of the meeting room, there are portraits of Sun Yat-sen and Chiang Kai-shek.There are four military officers standing on each side of the long conference table: the four on the left are the chief secretary Mao Renfeng, the chief of the operations department Chen Shixian, the chief of the intelligence department Yang Jirong, and the director of the radio station Yang Zhenyi; the four on the right are the telecommunications department Section Chief Wei Daming, Encryption Section Chief Liu Jie, Encryption Specialists Luo Junmin, Liu Jianru.

"Everyone, please sit down." After Dai Li went to the front and sat down, all the people sat down together. "I have called you today because there is an urgent matter. Secretary Mao, please introduce the situation to everyone first." Mao Renfeng stood up and said: "According to the information sent back by the station chief of Beiping not long ago, Japanese spies are going to carry out a conspiracy plan code-named 'Flying Snow' in Shanghai, but the details of the operation are unknown. In addition, we just detected I have received a coded telegram from them, please have a look." He took out the telegram from the folder and handed it to everyone for circulation.

After Mao Renfeng sat down, Dai Li asked again: "What do you guys think about this matter?" Yang Jirong said: "This coded telegram is likely to be the content of the 'Operation Flying Snow' that the Japanese spies will implement." Inevitably, and Shanghai is located in an eastern fortress where land and sea intersect, and it has a particularly important position in terms of politics, economy, military and other aspects. Japan launched the 'January 28th Incident' that invaded Shanghai five years ago ', although they failed to completely occupy Shanghai due to many reasons, since the signing of the "Songhu Armistice Agreement", their garrisons outside Shanghai have been increasing every year. They have a strong marine corps stationed in Hongkou, and they may Attack on Shanghai. I think 'Operation Snow' must have something to do with the Japanese invasion of Shanghai." Yang Zhenyi echoed: "Yes, as early as many years ago, the Japanese spy agency sent a large number of spies to lurk in various identities in various parts of our country. So far, countless huge spy networks have been formed in China. Over the years, They stole a large amount of information, and also carried out sabotage activities such as bribery, alienation, and assassination. All of these effectively cooperated with the Japanese invasion. It can be said that the "fifth column" they formed is even more harmful to us than the The powerful Japanese army on the front line is still terrifying. According to estimates, the number of Japanese special forces in Shanghai alone is almost the sum of the number of Japanese special forces in other regions of the country except the Northeast. Therefore, my subordinates speculate that the Japanese intelligence department will implement the "Operation Snow" It is likely that they want to use these agents to carry out all-round sabotage in Shanghai to cooperate with the Japanese invasion of Shanghai." The analysis of the two of them sounds clear and logical on the surface, but they all use the usual way of avoiding complicated issues in the officialdom, saying that they are not saying anything. Mao Renfeng saw that Dai Li was getting impatient, so he catered to him and said indifferently: "You two's dissertation is indeed very exciting, but this is a meeting of internal personnel, and we are not giving a report to the chairman, just Let’s stop talking about those well-known superficial questions?” Yang Jirong and Yang Zhenyi immediately looked embarrassed and fell silent. Dai Li nodded and said: "Please talk about how to deal with 'Operation Feixue' in detail." Wei Daming said from his professional side: "My subordinates believe that we should immediately organize an expert group from the cryptography room to try to decipher this as soon as possible. password, so that we can carry out targeted anti-'Flying Snow Operation'." Liu Jianru analyzed with the professional thinking of a cryptographer: "Yes, there are several similarities in this digital password, and it should not be difficult to start from here. " Yang Jirong said disapprovingly: "Technically speaking, even though it is possible to decipher even the most complicated code, what if it cannot be deciphered? Or before the code is deciphered, Rite's 'Operation Feixue' has already been completed. Then it will be too late." Luo Junmin took over and said, "Then can we find a way to steal Ritec's code book through Shanghai's inside line? Or arrest some Ritets who have already mastered it, and force them to ask 'Feixue' action' content?" Mao Renfeng was very disdainful of his opinions, but he was old in the officialdom and had a deep city, so he didn't show any emotion on his face. Instead, he analyzed sincerely: "The code book is a confidential document, and only the special agents and the generals in charge of translating the code There are only spies, and it is not easy to steal them. Moreover, the spies we have are all peripheral one-line spies. If we attack them, we can't get any valuable information. Instead, they are easy to scare the snake, so we can only monitor them for a long time. " Dai Li finally said: "Everyone's words are very reasonable. Based on your opinions, how about we start from multiple aspects at the same time?" Said yes. Dai Li stood up and said: "Okay, now I order..." Everyone stood up at the same time and stood at attention. Dai Li continued: "Immediately set up an anti-'Flying Snow Operation' team. It will be composed of Chief Wei Daming of the Telecommunications Division and Liu Jianru, Luo Junmin, and Liu Jie of the Cryptography Unit. Several cryptography experts formed an expert group to decipher this secret message!" The four took the lead and said, "Yes!" Dai Li continued: "For the sake of confidentiality, there is no need to call Shanghai District Chief Yu Lexing about this matter, and let a team under him take on this important task...Let the anti-interference group in Shanghai be directly responsible. Send power to the anti-interference group in Shanghai and let them temporarily Relax all the current work, and fully devote yourself to the anti-'Flying Snow Operation' directly led by the Bureau Headquarters." Mao Renfeng has already recorded these contents in the folder.Dai Li added: "This anti-'Flying Snow Operation' is a top-secret operation, and it must be controlled within a certain range of secrecy. In particular, Chen Lifu, Chen Guofu, and Xu Enzeng of the Central Committee must not be known. I will discuss with the Chairman." Report it at the right time. The success or failure of this operation is related to the honor and disgrace of our entire department and the interests of the party and the country, I hope you understand." Everyone replied in unison: "Understood." (Author’s Note: In 1938, the KMT’s Provisional National Congress was held in Luojia Mountain, Wuchang. After the meeting decided to reorganize the secret service organization, it was known as Zhongtong and Juntong. Before that, Zhongtong’s predecessor was CC It is the headquarters of secret agents in charge of the leaders Chen Guofu and Chen Lifu brothers. The predecessor of the military command was the Fuxinshe Secret Service Department in charge of Dai Li. After the victory of the Anti-Japanese War, the Central Command was changed into the Communication Bureau of the Central Party Members, and the Military Command was changed into the Secret Bureau of the Ministry of National Defense. Novel The story written in the first half is the military command that took place when the secret service headquarters and the secret service merged, that is, the old military command. "Military Command".) Shanghai, a city that has become an international metropolis in the East in the 1930s, is densely covered with buildings of embassies, banks, and offices at all levels. Cargo ships, passenger ships, and warships from various countries cruise on the Huangpu River. A vehicle travels back and forth on the street.The concession governments of various countries here have independent judiciary, there are many gangs, dragons and snakes are mixed, and all kinds of foreigners are mixed in the lively and bustling market, which seems dangerous and safe.Due to the complex environment, it has become a battlefield where spies from various factions gather and fight.The military command, central command, gendarmerie, and police of the Kuomintang, the Japanese Army, the civilian spy network, the Special Section of the Chinese Communist Party, the Korean Nationalist Party, the Korean Revolutionary Party, the Soviet Cheka, the British MI-6, and the intelligence agencies of the United States, France, and Germany, or Overtly or secretly engaged in various intelligence work here.Shanghai at that time was simply a paradise for adventurers and a paradise for spies. At the beginning of July 1937, the sun rose slowly from the East China Sea, Shanghai was very bright at dawn, and the French Concession was unusually quiet.In a gloomy room at 19 Keersey Road, four mysterious figures are holding a secret meeting.These four people are: Zhao Libiao, the leader of the anti-interruption team in the Shanghai District of the Military Command, Wang Kejin, the deputy team leader, Shen Xuehua, a spy correspondent, and Su Huijuan, the "Plum Blossom" who is known as one of the "Ten Golden Flowers" of the Military Command. At this time, one of them said, "I called you here today because there is a very urgent matter. Boss Dai sent an urgent message that Japanese spies will carry out 'Operation Flying Snow' in Shanghai, and the Bureau is currently deciphering the content of the operation. Boss Dai has instructed all of our internal and external agents to temporarily put aside other work and concentrate on anti-'Blizzard Operation'. I would like to ask you to share your opinions first." The person who spoke was in his forties, with a pair of His eyes were narrowed into a line, he had a long hooked nose, and his voice was hoarse. It was the team leader Zhao Libiao. A tall and fashionable young woman standing behind is Su Huijuan, a double agent secretly dispatched by the Central Command to the military command. She said: "The subordinates believe that we should start from two aspects: on the one hand, carry out the investigation on the Japanese special forces we have mastered. Surveillance or arrest, on the other hand, find a way to steal the enemy's code book." The rest of the people had no better way, and they all nodded in agreement. Zhao Libiao took a last puff of his cigarette, stubbed out the cigarette butt in the ashtray, and said, "Okay, from now on we will intensify our efforts to reconnaissance against Japanese special forces. Except for those already suspected and confirmed, as long as they are Japanese, or with Japanese Anyone who has contact, no matter what their status is, must not be let go. If there is not enough manpower, I can ask the police station to send someone to assist in the investigation for other reasons. If there is an important situation, it must be reported to the headquarters immediately, or decisively take corresponding measures. However , unless it is absolutely necessary, don't act too much, so as not to overwhelm the enemy." The three said in unison: "Yes." Zhao Libiao asked Su Huijuan again: "Miss 'Plum Blossom', has Taro Miyamoto done anything recently?" Su Huijuan replied thoughtfully: "I haven't detected anything for so long, he really looks like a responsible businessman." , not to mention that he hasn't lived in the Japanese territory, but in the British Concession." After a pause, he continued, "Well, of course, the more powerful the agent, the more he puts himself in the open, and the better at covering it up. Himself. If our suspicions about him are correct, he must be a big name in the espionage network, and he should also be an important member of the "Operation Snow". I work in his company, of course I can't find anything, and his Although the private residence is in the British Concession, there are many bodyguards and strict guards. However, recently my cousin Zhang Xiaolin has been in close contact with him, so I wonder if I can enter Miyamoto's residence through my cousin." Su Huijuan asked him eagerly for instructions, and in the Among the female spies in the army, it is rare to see her as passionate and patriotic. Zhao Libiao didn't show his emotions or anger, and he didn't say much, "It would be better if you can go in and check, but you must be careful." Su Huijuan said: "Thank you for your concern, team leader, I will." Zhao Libiao slowly picked up the teacup and took a sip of tea, then changed the subject and asked Shen Xuehua: "How is the situation at Mu Zhengying's family?" Shen Xuehua is just a young man in his twenties, with delicate features and a pair of myopic glasses. He replied: "After Mu Zhengying's death, Zhang Xiaolin, the leader of the Qing Gang, wanted to swallow the Mu Group, but the other two leaders of the Qing Gang, Huang Jinrong and Du Yuesheng Fearing that he would expand his power because of this, they used some means to contain him; on the other hand, Mu Zhengying's daughter, Mu Jianying, managed the Mu Group in an orderly manner, so it would be difficult for him to do anything." Su Huijuan took the words and asked in puzzlement: "What does this matter about the Mu family have to do with us?" Zhao Libiao explained: "Mu Zhengying of the Mu Group Company had a close personal relationship with the Communist Party when he was alive, and he also had business with Japanese businessman Taro Miyamoto. You know all about your dealings on the Internet. During the period when you were sent by Miyamoto to the Northeast to purchase goods, we conducted an investigation on Mu Zhengying and found that not long ago he helped the Communist Party transport a batch of imported western medicine, but because we We pursued closely and failed to ship it out of Shanghai. What’s abominable is that the agents of the Central Government deliberately leaked our actions to them in order to grab credit, so that they hid the medicine in time. As a result, the Central Government’s people did not find it, but instead It caught the attention of Japanese agents." "Then is there such an act of impeaching Zhongtong from above?" Su Huijuan asked cautiously.Although Zhao Libiao knew in his heart that Su Huijuan was actually sent by the Zhongtong to his side, he kept pretending not to know, and wanted to continue playing the game with the Zhongtong.He played with the teacup, sighed, and said, "It's not that Ms. Su doesn't know. For many years, there have been conflicts between our military command and the Central Command. The old man also turned a blind eye to it. We can only pretend not to know." "Would 'Operation Feixue' have something to do with that batch of medicine?" Wang Kejin, the deputy team leader with a mustache, didn't speak, and then he lost no time in bringing the topic back with the idea of ​​merging the case.Zhao Libiao shook his head and said, "Probably not. The matter of this medicine has long been a secret in Shanghai's espionage circles, and 'Operation Feixue' was just formulated by the Japanese, and it came from the Northeast. However, that batch of medicine came from under our noses." No, if we don’t find it out, we can’t hold our heads up, and we have to track it down.” However, Su Huijuan said worriedly: "Mu Zhengying must have told her daughter Mu Jianying where the medicine was hidden before she died. It is not easy to get her hands on Mu Jianying." Shen Xuehua sighed: "Yes, the reputation of the general door tiger girl It is not a false rumor. Mu Jianying, Mu Zhengying's adopted daughter, can be said to be a strange woman. Not only is she beautiful, but she is also as intelligent and bold as her father. He didn't dare to do anything to her. It stands to reason that the family property is passed on to the sons and not to the daughters. Even if he prefers his daughter, he can just share part of it with her. But Mu Zhengying actually passed all the property to this adopted daughter, and left nothing to the amorous His own son, Mu Jianquan, is really clever. After Mu Zhengying died, Taro Miyamoto, the underground party of the CCP and the Central Committee all approached Mu Jianying to find out the whereabouts of the batch of medicine. It may be that Mu Zhengying died He didn’t have time to tell his daughter how to connect with the Communist Party, or he didn’t want her to get involved in political struggles, so he didn’t plan to tell her about it.” Zhao Libiao said cautiously: "Mu Zhengying's son, Mu Jianquan, will return to Shanghai from Beiping tomorrow. According to reliable information, someone will attack him. Xuehua, take a few people to the train station to protect him secretly." "Why do we Want to save him?" Shen Xuehua seemed a little puzzled.Zhao Libiao said: "Mu Jianying has a paternal demeanor in dealing with the world, and has a pro-communist thinking. It is impossible to find medicine through her. Mu Jianquan is just a greenheaded lover. It is much easier to start with him. In addition , I think the Japanese will also get his idea, and we can use him to deal with the Japanese." Shen Xuehua said: "This subordinate understands, I will definitely protect him." "Team leader, our telecommunications reconnaissance station has captured some signals many times, and the radio waves appear frequently around Nanjing Road. It is very likely that there is a secret radio station of the CCP's underground party. Should we search Nanjing Road?" The matter has already been discussed, so he throws out another question in his heart. Zhao Libiao said: "Didn't I already tell Boss Dai's instructions? Temporarily relax activities against the Communist Party and concentrate on dealing with the Japanese. Besides, since the Xi'an Incident was peacefully resolved, the top leaders of the KMT and the Communist Party have held many talks to discuss The second cooperation and the joint resistance against Japan. If we take major actions during this period, it will cause a lot of trouble to the higher authorities. Therefore, the current policy for the Communist Party should be to monitor the Communist Party. If it is done cleanly, the superiors will still praise it." Wang Kejin nodded knowingly and said, "Yes, I understand." The rest of the people also smiled slyly. The bright sun shines on Shanghai, a beautiful oriental metropolis.On Nanjing Road, there are exquisite buildings in a patchwork pattern, and the streets are full of traffic, people coming and going, bustling.The smoke of war has not yet permeated here, and the tense situation has not affected this bustling city. A middle-aged man was sitting in a running rickshaw, wearing a white suit and a white top hat, and was reading the "Declaration" of the day.The rickshaw stopped in front of a bookstore.After getting out of the car, the middle-aged man paid the driver and sent the driver away. He looked up at the plaque on the top of the door that said "Wanjuan Bookstore", and he couldn't help feeling warm and excited.He looked around, took off his top hat, and walked into the bookstore. This bookstore is not big, and several bookshelves are full of books.Several guests were flipping through the pages, and among them was a handsome young foreigner who was seriously drawing on a book with a pen. It seemed that he had decided to buy the book in his hand. The boss at the counter is an old man in a long gown and a pair of reading glasses.The boss was reading a book. When he saw a visitor, he put down the book and said with a smile, "Sir, do you want to rent a book or buy a book? Please read as you like." The middle-aged man glanced into the room and said with a smile, "None." The bookstore owner wondered, "Then... what's your business?"The middle-aged man approached the boss and asked cautiously: "I have a batch of pirated books that I want to sell. I wonder if you are interested?" : "Look, sir, I have so many books here that I can hardly put them down, not to mention yours are not genuine." The middle-aged man continued to sell: "But the quality is comparable to the genuine ones, and readers can't tell the difference. Yes." Hearing this, the bookstore owner was a little tempted, "The price..." The middle-aged man said: "Compared with the original book price, how about a 20% discount?" The bookstore owner showed a disbelieving expression: "It's too low, and you will suffer." The middle-aged man smiled and said: "As long as there is profit, we are after small profits but quick turnover." The bookstore owner seemed to have been moved by him, and asked again: "What kind of books are there?" The middle-aged man whispered: "Whatever you want, including Ban the book." "In this case, let's go into the room and discuss it in detail." The middle-aged man said: "Please lead the way." Even if these secret conversations between the two of them were overheard by ordinary people, they would only think that they were doing ordinary illegal things.That foreign young man is not an ordinary person. He has written down the conversation between the two in the blank space of the book, because although he can speak Chinese, it is not his mother tongue after all, and he knows how to analyze such joint code words. There can be no discrepancy. The owner of the bookstore shouted to the back room: "Xiaohu, come out and look at the store." A young man with a crew cut ran out in response.The bookstore owner led the middle-aged man into the back room. After closing the door, he turned around and held the middle-aged man's hand, and said excitedly, "Comrade Commissioner, we have been waiting for you for a long time." The middle-aged man said happily: "I am Yu Shaoyun." The bookstore owner said: "My name is Guo Defu, and several comrades from our group are waiting for you below." Then he opened a wooden floor and led Yu Shaoyun down the stairs , Entering a secret room, the space in the secret room is very small, two men standing inside are flipping through materials, and two women are sitting in front of a Morse radio station working.When several people saw the two coming down, they all stood up to greet them. Guo Defu introduced: "Comrades, this is Comrade Yu Shaoyun, the special commissioner who came from Nanjing." All four said happily: "Hello, special commissioner." Yu Shaoyun shook hands with the four people one by one. A middle-aged man in a long gown first introduced himself: "Huang Yifu, the leader of the second group of the seventh branch of the Shanghai Underground Party. We received a telegram from the organization yesterday saying that there is Comrade wants to bring important information from Nanjing, we are all very happy, finally we are waiting for you." Yu Shaoyun said: "I kept you waiting for a long time." Another young man said happily: "Hello, chief, my name is Li Dahu, the one who went out just now is called Xiaohu, he is my younger brother." Yu Shaoyun patted him on the shoulder and said with a smile: "He looks quite similar." Then a lesbian introduced himself: "My name is Chen Jing. I met you when I was studying in Nanjing Medical University. It was because of your speech that I took the revolutionary road. My current public identity is the French Concession An intern in a hospital." This Chen Jing was in her twenties, with a dignified and beautiful face, softly speaking and smiling.Two faint dimples were exposed around the mouth, silky hair was scattered on the chest, and the slender figure looked graceful under a white dress, like a flower in bud.Yu Shaoyun smiled and said: "It seems that we are old comrades in arms." The last woman who shook hands with him looked only 17 or 18 years old. She was dressed in a school uniform, with two braids, a delicate and beautiful face, and said with a smile on her face: "My name is Wang Ling. Please give me some advice from the special commissioner." Yu Shaoyun said with a smile: "There is a shortage of radio operators in various places now, and many trainees start working before they graduate. Although you have just graduated, you are amazing, and I don't know anything about telecommunications, so I still have to I need you to teach me." Wang Ling smiled and said, "That's no problem." Everyone couldn't help laughing. Yu Shaoyun said again: "Comrades, you have worked hard for many years of underground work." Huang Yifu said: "Thanks to the chief for his concern for us. It is our duty to contribute a little bit to the motherland that is full of disasters. I don’t know what is the important task this time?” Wang Ling also asked anxiously: “Yes, you came to Shanghai from Nanjing in person, you can’t just give us condolences!” Huang Yifu said: "You brat, why are you so rude, do your job well." Wang Ling made a grimace, and whispered: "A high-ranking official crushes people to death." In front of the radio station, I looked at my watch and saw that the time agreed to contact my "home" was approaching, so I put on my earphones and adjusted the radio station. Yu Shaoyun smiled and said, "Old Huang, don't be so cruel to the little comrades! Our little girl is angry with you." Everyone laughed again.Yu Shaoyun said again: "I was ordered to rush to Shanghai from Nanjing this time. I really want to complete an important task with all your comrades. According to the information provided by our comrades who penetrated into the Kuomintang's military system, Japanese spies will carry out crimes in Shanghai. "Operation Flying Snow". But I don't know what the content of "Operation Flying Snow" is. Team Leader Huang, let me tell you about your situation first." Huang Yifu said: "Since the peaceful settlement of the Xi'an Incident, the persecution of us by the secret agents of the Kuomintang military and central government has not been as crazy as before. On the other hand, it is also because of the rampant activities of Japanese and puppet secret agents that they have to be distracted. Now all walks of life in Shanghai The anti-Japanese sentiment among the masses is very high, and it is easy to mobilize the power of the masses, but there are also a large number of traitors colluding with the Japanese." Yu Shaoyun sighed: "According to the analysis of the current domestic situation, the Japanese army will soon invade Shanghai, and they will definitely use their spies lurking in Shanghai to carry out a series of sabotage before the invasion. The Party Central Committee has clearly instructed us to mobilize the masses and unite All the forces that can be united are fully resisting the Japanese army. Now, the main task of your team is to counter the 'Operation Snow'." Huang Yifu solemnly said: "We will definitely complete this task entrusted to us by the party." Suddenly, the Morse radio station rang, and Wang Ling concentrated on it, saying: "'Home' call..." Hastily pressed the electric button to answer, grabbed a pen and paper, and quickly recorded the received signal into a code. Morse code was invented by American Morse in 1844. Morse code is some dots (.) and pictures (-) that represent numbers. , paintings, and pauses in between, allowing each character and punctuation to be sent independently of each other. This code can be transmitted with a radio signal with a steady tone and intermittent radio signals, usually called continuous wave (Continuous Wave) , abbreviated as CW.It could be an electrical pulse in a telegraph wire, or it could be a mechanical or visual signal (such as a flash of light).Generally speaking, any coding method that can represent written characters with variable-length signals can be called Morse code.But now the term is used to refer only to two types of Morse code that represent English letters and symbols: American Morse code is used in the wire telegraph communication system; (pause removed).Morse code is composed of dot (.) and (-) symbols according to the following principles: 1. One point is a basic signal unit, and the time length of each drawing is equivalent to the time length of three points. 2. Within a letter or number, the interval between each dot and each drawing should be the length of two dots. 3. The interval between letters (numbers) and letters (numbers) is seven points in length. The sounds transmitted through the telegraph are: 1: tick 2: tick 3: tick 4: tick 5: tick tick 6: tick tick 7: tick tick 8: tick Didi 9: Answer Didi 0: Answer If it becomes the strokes written when recording, it is: 1 (.-) 2 (..-) 3 (…--) 4 (….-) 5 (…..) 6 (-….) 7 ( --...)8(-..)9(-.)0(-) The other English letters are transcribed as follows: A(.-)B(-…)C(-.-.)D(-..)E(.)F(..-.)G(--.)H(….)I(..) J(.---)K(-.-)L(.-..)M(--)N(-.)O(---)P(.--.)Q(--.-) R(.-.)S(…)T(-)U(..-)V(…-)W(.--)X(-..-)Y(-.--)Z(--. .) Punctuation: Period (.).-.-.-colon (:)--.comma (,)--.--semicolon (;)-.-.-.question mark (?).--.equal sign (= )-.-ellipsis(...)...--.slash(/)-.-.exclamation point(!)-.-.-hyphen(-)-.-underscore(_).--. - Double quotes (").-.-. Front parenthesis (()-.--. Back parenthesis ())-.--.- The Chinese characters in the general plain codebook have corresponding codes to represent them, such as the above mentioned: 1532 (Cuo) 5115 (Cong) 4214 (瞀) 3162 (汧) 5451 (Guan) 4221 (恶) 1126 (夤) Wait.In fact, even an ordinary telegraph translator can memorize the codes of hundreds of Chinese characters, and Wang Ling, who has undergone special training, can memorize the codes of thousands of commonly used Chinese characters.If she received plain-coded telegrams, she could write Chinese characters directly at her level, but now she was receiving coded telegrams, she had to write out the telegrams she heard first, and then translate it against the complicated cipherbook. For simple passwords, telegraph translators can also translate them directly from memory. The rest of the people surrounded them, all holding their breath, and the atmosphere in the small space became even more tense.After receiving the translation, Wang Ling took off the earphones.Yu Shaoyun asked anxiously, "What's the content of the document?" Wang Ling read the translated content: "The East China Intelligence Department reported that Soviet spies secretly photographed a top-secret document that the Japanese Kwantung Army intelligence agency was about to send to Shanghai..." As he spoke, he handed him a telegram, "The content of the document is written in code, and the experts at 'home' are currently deciphering it, and we have to decipher it ourselves." Several people looked at the telegram together. The content of the telegram was: Secret No. 16007 出します: Intelligence Department of the Kwantung Army は收めます: Shanghai の 206 Information Room 1937, July, One SGRLSIWIGJRIFDUGAYVNGJLNYLETFLDWYDBNLBEYVGEYEWIBIIJALFJVNLUFAABVLAYIUUYJBGKYW NYLWWLVH MGAA OY WNYUGDBWVNIGVYGJJIDW NVNGJLJIDWNVNGJLLUWYDWNYMLDBNLJPNLG MG AA OYVISYWNYUIVFBIULWWLVHIJIFDSGAGWLDRIO ZYVWGKYBBNLJPNLGLAAIUWNYSGAGWLDRGJWYA AGPYJVYIXYDLWGIJBWNYLDSRLJEJLKRIUWNYGJW YAAGPYJVYLPYJVGYBNLKYVIAAYVWYEKYDREYWL GAYERIFJYYEWIVISXAYWYEORWNYEYXLDWSYJWBS GBBGIJGBWILBBGBWGJWNYVISXAYWGIJIUBJIMVNF LJELIULJPCGXALJIU LVWGIJBNLJPNLGVYAYODGWGY BUDISLAAMLAHBIUAGUY MGAAXFAAIKYDYKYJ GU GVLJJIWOYFBYEOFWLABILBULDLBXIBBGOYAWNYG DBWLRGJBNLJPNLGYKYJGUGWGBWIWDRWINYAXW NYSAGKYJYLDWNYODGWGBNLJEUDYJVNVIJVYBBG IJGJIDEYDWIDYWLGJWNYLDSRBWLWGIJYEGJBNLJ BNLJPNLGLUWYDWNYXIAGWGVLALJEYVISJISGVVL XGWLAGUGWVLJJIWOYAYUWOYNGJELJEHGAAWNYS LAAVNGJLBOFDYLFIUGJKYBWGPLWGIJLJEBWLWGB WGVBIUWNYSGAGWLDRVIFJVGALJEWNYVISSGBBGIJ LJEWNYVNGJYBYVISSFJGBWBXGYBWIWLHYVIDDYB XIJEGJP SYLBFDYBOFWBNIFAEWDRWILKIGELSLZIDV IJUAGVWMNYJLAAWNYSLGJLVWGIJBYVDYWVNFJL ELIULJPCGMGAAVISYWIBNLJPNLGUIDLAAXDIZYVW BLJEBIAYARDYBXIJBGOAY UIDNYD。 黄逸夫问道：“我们现在该怎么办？”余劭昀回答道：“这份电文的内容可能就是'飞雪行动'的内容。我们得从两方面入手：一方面争取尽快破译出密码；另一方面动用我们所有的特勤人员加大侦察力度，弄清敌人的这次阴谋。”黄逸夫道：“特派员说的是，破译密码的工作就由王玲负责。”又对余劭昀讲解道：“我们这个小鬼，不但是我们的千里眼顺风耳，而且还是破译密码方面的天才，曾成功破译过国民党和日本人用古诗词和文学着作等编译的密码。” 王玲道：“这些字母很可能是代表哪一国的语言，最可能是日语，但是具体是什么还无法确定。至于密写方法，一种是无规则的错乱排列，如果是这样还不难，只需玩一次颠倒字母的游戏；另一种是按编定好的对应字母互换表，甚至还要按周期变换，如果是这样，可就要稍微麻烦一点点了。当然，这只是最常见的两种字母编写密码的方法，也很容易破译，还有更复杂的呢，而且这密码太短了，仅仅凭这一份电文，不易找到突破口。我实在是没有多大的把握，不过有个人是这方面的天才，她一定能破译出。” 黄逸夫问道：“谁？是我们党内的同志吗？”王玲无奈地摇头道：“不是，她是我的小学同学，但是后来她跳级远远走在了我前面，就是沐家二小姐沐涧颖。我编写密码和破译密码的技术全是她从日本回国后教我的。在延安学习时，我把她教我的技术讲出来，教官也非常佩服。” 黄逸夫正色的开始用共产党官员常用的语气说教道：“小王同志，我们做的是机密工作，工作纪律是'上不告诉父母，下不告妻儿'，就是在内部也要慎于言、严于行，怎能透露给外人？而且，我们也不能再去麻烦沐小姐了，她的工作都够她忙了。你还是自己想办法破译吧，我们对你有信心。” 王玲想说，其实现在他们这个小组所用的其中一套中文密码的编写方式还是沐涧颖教她的呢，那就是汉字互换法：将几千个常用汉字选出来，按照一定的拼音规律排列成多组，各组汉字个数相同，一一对应，加密时用对应的字替换。比如要加密“中华民族是不可战胜的”这句话，现在用一种三组编码的方法来加密： 1.天水炮军杀后中可机不 2.胜华决地南族下的飞女 3.是药战米弹死复车民兵 就可以用1——2——3——1（即需要用到第一组中的某个汉字时就用第二组中与之相对应的汉字替换，同理，第二组的就用第三组的替换，第三组的用第一组的替换）的方式替换加密成：“下药机死天女的炮是车。”解密方用同样的密码表反过来推就可以还原。当然为了加密方和解密方的工作效率，需要按照一定的拼音规律来编排汉字，为了加强保密等级，还需要按照通讯双方事先约定好的方式进行按日周月进行一些汉字位置的变换。王玲自己也认为这套密码的等级特别高，敌人很难破译。因为这样的密码的密钥就是一部厚厚的密码本本身。 沐涧颖曾经告诉过她，用诗词、小说、字典等编写密码都是十分常见的，如果破译方一旦分析出加密者用的是什么诗词、小说、字典，破译出来也就很容易了。其实对于单表字母替换密码最有效的破译方法是用频率分析法，因为无论是英语、德语还是其他字母（包括我国现在用的汉语拼音）语言，二十六个字母的出现频率的高低都是可以统计出来的，无论你怎么变换字母，根据其出现的频率高低，比如英语中出现频率最高的是字母E，出现频率第二高的字母是T。有点像古汉语在活字印刷时代，人们也是按照汉字使用频率来雕刻各汉字的多少，比如“之乎者也”之类在文言文中出现频率特别高的汉字就雕刻得特别多来备用。按照这个思路，再做一些适当的微调和语言学上的猜测，以及观察，经验，归纳，排除，演绎，分析，假设，文字连接的特征和语言连接的特殊性等，一个个辨认并标定其他字母甚至字母组合，完全可以将密文的字母全部还原为明文字母，进而彻底破译明文。其实汉语编写的密码破译难度要比英语等编写的高得多，因为英语等语言无论你怎么加密，通篇以及无数篇电报中都是二十六个字母在变换，而汉语的复杂性决定了一封电报的内容中重复的汉字会很少，而且完全可以在编写密码时避开重复。破译密码最重要的可能还是人的天赋，虽然从教育大众的角度讲，成功靠的是努力，即使提到天赋也只能占百分之一。但是历史告诉我们，那些成功破译敌方复杂军事密码的密码专家们确实称得上是天才，主要是数学和语言学方面的。 但是她还是没有说出这些秘密来。毕竟这些专业的密码知识普通人是难以理解的。但让她想到的另外一层却是：为什么上级会把密码原文发来？按理说在各个通讯部门是都不应该有这样的事情的。密码专家当然都是聚集在总部机关的，破译密码那是他们的事情。当初她在接受电讯学习时，教官偶然知道了她具备密码破译的能力后，就有了让她继续深入学习密码知识的想法，虽然当时的共产党党内严重缺少具备相当高文化程度的人来从事电讯工作，但是比起有能力从事密码破译工作的人而言还是要多得多的，像她这样的人才肯定是要被安排在总部工作的，因为这样的人才是不能被派到上海这样危险的地方来冒险的，而且在上海也不具备专心破译密码电报的条件。狡猾的她也意识到了上面的决定，而她心里明白，自己不能留在总部机关，一定要回到上海，因为这里还有她自己的事情等着她来完成，那就是查清楚父母的死因，要为爸爸妈妈报仇，虽然私自行动调查是违背纪律的，但是不成熟的少女的心情还是使她决定要这么做。于是后来就假意对密码不感兴趣，面对交给她的密码也开始反应得特别迟钝，一份都破译不出。又因为本身就是上海人，在要求回到上海工作后很自然地就得到了批准。可是来到上海后却又奇迹般地破译出了些自己所截获的日本人和国民党的密码电报，她以前的教官觉得奇怪，要求发回密码原文查看，但是她却胡乱地把那些密码原文改成特别简单的初级密码发回去，这也算是违反纪律的事了，但是少女顽皮的性格却使得王玲就这么把上级欺骗了，而她身边的人对密码一窍不通，自然不知道她所搞的这些手脚。反正她是不想被调回总部机关的，欺骗就欺骗了呗，再说自己又没有任何恶意。所以对于上级发来的这份密日军码电报，她突然想到会不会是一份假的电报，只是那狡猾的教官的鬼主意？拿来欺骗我？是想考察我的破译水平？但是她马上就明白过来，现在这里的工作量这么大，上级是不会拿一份假的密电来开玩笑的，但是借用这份电报顺便对她进行考察的用意肯定还是有的。不管怎么样，还是要尽全力破译的。至于成功破译后自己会不会被调回那就是后话了，大是大非的事情她还是会很认真地对待的。 陈婧道：“对呀！说不定还能青出于蓝呢。”王玲撅起小嘴道：“站着说话不腰疼。破译密码犹如海底捞针，那是没有办法的办法，十套密码中能破译出一套也算是万幸了。你认为容易，你来破译好了，译出了更是蓝胜于青了。”几人听了又都笑了起来。余劭昀笑道：“小鬼又闹情绪了。” 黄逸夫严肃地道：“在密码学这方面，你婧姐姐可没你的本领大。她可有另外的任务。” 陈婧喜道：“什么事？”黄逸夫道：“你中学时的老同学沐涧泉明天要回上海了，你负责到火车站接一下他。”陈婧脸色微变，奇道：“他……”不由得陷入了沉思中，隔了一会儿又道：“我去……”黄逸夫道：“这可是党组织交给你的重任。” 余劭昀道：“老黄，这个沐涧泉到底是什么人？”王玲笑道：“那个沐涧泉可是个痴情种，为了爱情放弃亿万家产，在上海可是出了名的。婧姐姐，你和他既是中学同学，而且还是远房表姐弟，听说你们俩……”她故意不往下说，好比用枪指着别人却迟迟不开枪，让人心中比死还难受。 陈婧趁她没开枪，反驳道：“狗嘴里吐不出象牙，你不说话没人当你是哑巴。你当他是偶像，那你嫁给他得了，他妹妹不是教你密码学的老师吗？现成的媒人。你嫁给他就成了我表弟媳妇了，我们的关系也就更亲了。”王玲向黄逸夫道：“黄组长，你看她。我可没说她什么吧，她却这样来编排我。” 黄逸夫听到这些婆婆妈妈的谈话，有些不耐烦地道：“好了，你们俩都不许再闹了，让特派员听了可要说我没好好管教你们。”余劭昀笑道：“这可是他们年轻人的美好生活方式，他们为了祖国抗战已经放弃了很多应有的欢乐。我们也不能因为战争和工作，让他们连玩笑也不能开嘛。”陈婧笑道：“谢谢首长关心。”王玲笑道：“还是特派员说得有道理。” 黄逸夫笑着无奈地摇了摇头，对余劭昀说道：“这个沐涧泉倒没什么，但他的父亲沐正英先生生前帮过我们很多忙。前些年由于我们内部的不完善和党内叛徒的出卖，以及国民党的疯狂镇压，使得我们上海地下党损失惨重。我们有好多同志都是在沐正英的暗中保护下脱险的。沐正英是身份显赫的巨商，树大招风，黑白两道想打他主意的人很多；他暗中帮助我们的事，中统和军统的人也有所察觉，也可能对他家人下手；日本商人宫本太郎也极力接近沐正英，而据我们多方面收集的情报分析，宫本太郎很可能是日本的大特务，也会对沐家不利。另外，前不久沐正英帮我们送过一批药品，由于国民党查得紧，他只能将药品藏了起来，那批药品的下落，可能只有他女儿沐涧颖知道，我们不但要通过他们兄妹寻找那批药品，还要保护他们的安全。如果他们出了什么事，我们就对不起沐老先生了。” 余劭昀点头道：“不管他的后人愿不愿意继续帮我们，我们都应该保护好他们。”陈婧道：“请二位首长放心，我会完成这项任务的。”她心里不由得在想：已经几年没见的沐涧泉会是什么样了呢？他还是像以前一样吗？希望他别被卷进这些斗争中来。
