On September 27, 1950, it was sunny, and Dongdan Street in Beijing was already full of traffic and bustling early in the morning. At about 9 o'clock in the morning, an Iraqi woman came to the Beijing International Telegraph and Telegraph Post Office in Dongdan gracefully with a printed silk scarf on her shoulders.She finished the mailing formalities quickly and left in a hurry. A tall, fat Japanese man who was watching her in the "Northern Leather Goods" shop across the road saw the woman coming out of the post office and was sure that the mail had been sent, so he lowered his top hat and followed the woman towards East Fourth.

Just when the senders thought they were safe, their letter was placed in front of Director Di Fei of the Investigation Department of the Beijing Municipal Public Security Bureau who had been monitoring them for a long time.Literally, this letter seems to be just a purchase and sale notice. The delivery address of the letter is written in a brush: Shibuya District, Tokyo, Japan First Green C Management Room, No. 7, 20, Shenquancho After secret inspection, the content of the letter is: CLC headquarters: The purchased fire extinguishers are scheduled to be shipped on October 1st.Everything is going according to the established plan.

Warm greetings! Ryuichi Yamaguchi There was nothing unusual about everything, but Director Di Fei felt something strange when he analyzed it.First of all, CLC is an espionage organization and has no business in firefighting equipment. Why did it buy firefighting equipment and choose Beijing?Secondly, Ryuichi Yamaguchi is a catalog editor of the Chinese Department of the French Library, not a businessman. Why did he buy a fire extinguisher for the CLC headquarters? Looking at the letter again, in addition to the letterhead with the content of purchasing a fire extinguisher, there is also a sketch of Tiananmen's topography drawn with a pencil, and it also draws the indicated target for shooting the Tiananmen reviewing platform: the fire extinguisher placed from the Yuhe Bridge On the plane, a thick and black parabola pointed directly at the portrait of Chairman Mao in the center of the Tiananmen Gate.

Di Fei was taken aback and had a premonition of the seriousness of the problem.After taking the photo, he immediately reported to Li Guoxiang, Director of the Investigation Division of the Ministry of Public Security.Li Guoxiang immediately held a case analysis meeting. At the meeting, everyone felt that there was a big conspiracy hidden in this letter, and Tiananmen Square was in danger.Today is September 27, and four days later, it will be the first anniversary of the National Day. At that time, the leaders of the party and the country will climb to the Tiananmen Gate to celebrate this grand festival with the people... This date is exactly what is stated in the letter. The "shipped" day of the .What "goods" will they "send"? If you connect the "sent" "goods" with the parabola on the sketch...

Everyone didn't dare to think about it anymore, but then their hearts were raised in their throats. "I'm going to ask the central government for instructions!" The problem is too serious, and if analyzed correctly, the consequences will be disastrous.Li Guoxiang hurried to Zhongnanhai. Comrade Peng Zhen, a member of the Political Bureau of the Central Committee of the Communist Party of China and the mayor of Beijing, listened to the report in the Xihua Hall and saw the evidence. Comrade, a major case of sabotaging our national day! Solve the case quickly without delay!"

Li Guoxiang was ready to leave after taking the order.Comrade Peng Zhen also said: "It is necessary to strictly distinguish other personnel who have no direct connection with the case, and only arrest the main criminal. Other personnel must be quickly investigated, interrogated, and released quickly, even if they are from the former US Strategic Intelligence Agency. Personnel, as long as they are not directly related to the case, they should be treated differently, and they will not be allowed to touch them without evidence. This case is the first major foreign-related case, and the international impact is huge, so there must be no mistakes."

In fact, as early as July 1950, with the outbreak of the Korean War, Cao Chunzhi of the Investigation Section of the First Bureau of the Chinese Ministry of Public Security had already begun to collect materials on international spies in order to prevent the destruction of foreign hostile forces.After reviewing a large amount of data and investigating suspicious persons, the target was quickly locked on an organization set up by an American in Dongsi Santiao, Beijing - the "U.S. Information Service". The "U.S. Information Service" is actually a branch of the U.S. Office of Strategic Intelligence in China. People who often come and go here are expatriates from defeated countries such as Germany, Italy, and Japan who have lived in Beiping and Tianjin for a long time.Some of these nationals from the defeated countries were spies in the past, and were bought by the United States after the end of World War II to continue to engage in espionage activities.

After observing the "U.S. Information Service" for many days, Li Andong first entered the investigation line of sight.Soon, outside investigators got hold of Italian Zheli, Japanese Yamaguchi Ryuichi, German Ganus, and Dongjiaominxiang French library manager Wei Zhi who had close contact with Li Andong. Li Andong, an Italian, also known as Tony, lives at No. 17 Ganyu Hutong B, District 1, Beijing.His public identity in China is the agent of Tianjin Laoshichang Company in Beijing.This person came to China in 1919, opened Yiya Company in Tianjin from 1923 to 1924, and sold arms to Beiyang warlords many times. In 1926, he organized the Beiping branch of the Fascist Party in Beijing and served as the head of the branch. In 1934, he served as the secretary-general of the Italian Air Force Guidance Group and assisted Chiang Kai-shek in purchasing a large number of aircraft from Italy many times. After the "July 7th Incident", Li Andong collected intelligence for the Japanese invading army in various regions of North China. In March 1948, he accepted the espionage mission assigned by the military attache of the U.S. ambassador to China in Beiping, Colonel Paul Bold, and under the instruction of Bold, he recruited Japanese, German and other spies to act as intelligence agents for him, and continued to carry out the mission. espionage.

Ryuichi Yamaguchi, Japanese, lives at No. 16 Ganyu Hutong B, District 1, Beijing. In 1938, he came to Qingdao and served successively as the director of the Beijing Office of the Japanese-Puppet "North China Shipping Industry Association" and the Japanese-Puppet "North China Shipping Industry Federation". Japanese Navy Ministry. In 1948, he had a spy relationship with Li Andong.After the liberation of Beijing, he had directly accepted the spy mission assigned by Boulder.His public identity is the editor of the catalog of the Chinese Department of the French Library opened by Frenchman Wei Zhi in Dongjiaomin Lane.

Ganus, a German, used to be a member of the German Nazi Party. He lives at No. 17 Ganyu Hutong C, Second District, Beijing. In 1938, he came to Beijing and served as the agent of German Bosch Company in Beijing. In 1940, he met Li Andong. In 1945, Ganus served as an electrical engineer at the U.S. Consulate in Peiping, and at the same time worked with Li Andong to collect intelligence for American spies.His public identity is the manager of the West City Automobile Company.In fact, this auto shop only has one small sleeper car, which is for his use, and the workers only rely on the money usually used to repair the car as expenses.

Zhe Li, an Italian, lives at No. 15, Nanchi Gongfu Square, Fifth District, Beijing. In 1921, he came to China and served as the Italian customs governor in Tianjin. Since 1943, he has been doing espionage work for the Japanese invading army.After Japan surrendered, he had a spy relationship with the US spy agency.After Beijing was liberated, Bold left Beijing and took away his wife, the Russian woman Horvart Evna, and he is now an unemployed expatriate. Maliyue, an Italian, is the bishop of the Catholic Church in Naiz Prefecture. Shortly after Ma Liyue came to China in 1946, Li Andong ordered him to provide him with information about China on the condition that he would be paid $140 a month and $5 for each trip.After the liberation of Beijing, Ma Liyue continued to provide services to Li Andong, and the sacred and pure land of the Catholic Church became a sinful place where Li Andong and others hid their weapons. As the investigation deepened, Cao Chunzhi filtered out an Iraqi woman who opened a smoked fish shop in Dongjiaomin Lane through contacts with embassy staff from various countries. She was also the woman who sent the letter.Investigators quickly deployed and controlled the above-mentioned personnel. Just as the investigators were monitoring Li Andong and others, a woman from Hong Kong came into everyone's sight. On September 25, 1950, a handsome young woman walked into Zheli's residence.After a while, Liu Feng, a "special situation" officer sent to Zhe Li's house as a "handyman", opened the door, sent the woman away, and then hinted to the scout Xin Lixue who was repairing shoes across the road. Xin Lixue slammed on the shoe repair tool again, signaling to Shen Jizong, a distant scout, to keep an eye on this target. At 4:00 p.m., the investigator Shen Jizong, who was good at "moving around" during the follow-up, returned to the investigation department to report to Cao Chunzhi. After follow-up investigation, the woman was Cheng Meng, who lived at No. 770 Naizfu Street, Beijing, and graduated from Yanjing in 1950. University music department, currently teaching assistant in the music department of Beijing Normal University.According to the school's investigation, on the eve of the liberation of Beijing, when Cheng Meng was studying at Yenching University, he had studied piano alone with the Soviet Union's Holvart Evna. Cao Chunzhi judged: Cheng Meng came to find Zhe Li for a connection, but she was not the real one, there was someone behind her.As expected, the neighborhood committee introduced: Cheng Meng's eldest sister, Cheng Na, recently came to Beijing from Hong Kong to visit relatives and applied for a temporary household registration.Cheng Na is also a graduate of Yenching University. Her husband is an Englishman who opened a bank in Hong Kong. The emergence of this situation made the investigators realize that Boulder, Li Andong and others must be conspiring to plan this big conspiracy.Cao Chunzhi immediately decided to send investigators Xin Lixue, Shen Jizong, and investigator translator Zhang Baoying to Cheng Na's residence to carry out a secret search mission. The investigators rushed to Cheng Na's residence quickly, explained their intentions, and hoped that she would cooperate, but she sternly refused, and the search could not be carried out. After Cao Chunzhi learned of this situation, he drove there immediately.His majestic gaze made Cheng Na panic.After Cao Chunzhi asked Cheng Na's name, he looked around the room and suddenly pointed to the dressing table and asked, "Have you checked this?" "No." Zhang Baoying replied. "examine!" Zhang Baoying opened the small cabinet of the dressing table, and saw a delicate American-made cosmetic powder box inside.As soon as it was opened, half of the business card was exposed from under the foundation, with English letters printed on it. Cao Chunzhi said to Zhang Baoying: "You English expert, see whose business card it is." "It belongs to Bold, Colonel and Military Attaché of the former embassy in China." Cao Chunzhi said to Cheng Na and Cheng Meng solemnly and directly: "Boulder's public identity is the military attache of the Beiping Military Attaché Section of the US Embassy in China, and his secret identity is the head of the US Strategic Intelligence Service in China. You are under contract. To carry out espionage activities in the capital of China under the instructions of Erde, this one is the evidence of the crime!" The Cheng sisters, who had ghosts in their hearts, remained silent for a while. After a while, Cheng Na said to Cao Chunzhi: "I'm here to see my mother. Entrusted by my husband's friend Boulder, with the half of his business card as proof, I asked Mr. Zheli to help sell Horvath Evna. The piano stored at my sister's house. My sister has already contacted Zhe Li." "Selling pianos? Holvat Evner and Jerry, they were and are husband and wife, and they both have the right to sell their own pianos. Is it still up to Boulder to decide? Boulder asked you and Zheli Check the half of the business card to show that you are connected, there must be a major conspiracy here!" "This is what my husband told me to do. There's nothing to write about here." Cheng Na explained again and again. "To sell a piano, just write a few words. What are you doing with the business card! You have to be honest!" "He asked me to ask Zhe Lihao on his behalf, and told him that our foreign bank's money is tight and business is not very good!" "That's right. Zheli is not a capitalist, and your foreign bank's money is tight. What does it have to do with what Zheli said? Do you understand what this means?" Cheng Na shook her head. "This is the language of spies, giving instructions to them!" "My God! I didn't know that my husband was that kind of person, causing me to commit a crime unknowingly." Cheng Na began to cry as she spoke. That night, Cao Chunzhi took Cheng Na to the Ministry of Public Security. "Please sit down! You are a guest here." Cao Chunzhi said politely, "It will be safer for you to come here, just explain the problem clearly. I promise you will return to Hong Kong happily and safely." Seeing that Cao Chunzhi turned out to be such an approachable person and had such trust in herself, Cheng Na choked up, and said, "I am Chinese, and I am willing to do things that are beneficial to the motherland. So, how can I contact you in the future?" "I'm going to let Cheng Meng be your contact person, okay?" Cheng Na nodded. Cao Chunzhi then ordered Cheng Na: "You go to see Zheli at the agreed time tomorrow, do as Boulder asked, and then return to Hong Kong on time. Don't move anywhere in Beijing, and don't contact anyone. If you don't obey me, don't blame me. Turn your face and deny anyone!" Cheng Na smiled and agreed: "Mr. Cao, don't worry. I will do it!" In the Heidemann Cafe in Beijing, Cheng Na gave half of the business card to Zhe Li according to Cao Chunzhi's instructions. Zhe Li took the business card and was very happy, feeling that everything was going according to the original plan.Then, he drove a gray car to Li Andong's residence quickly. Li Andong, who was dreaming, was eagerly waiting for the contact code sent by Boulder from Hong Kong.As long as the business cards are matched, it means that Boulder gave them the final order, and then fed back the information and reported it to the intelligence office of the U.S. Oversight Command in Tokyo, Japan. In this way, his plan to shock the world will be implemented. It turned out that before Boulder fled the mainland in embarrassment in 1949, he had a secret conversation with Li Andong.During the private conversation, Li Andong said unabashedly: "I still have a Stokes-style mortar hidden there, and dozens of shells, grenades and other weapons." Bold asked sensitively: "How are you going to use these weapons?" "I plan to have the opportunity to use it in the future." "What opportunity do you encounter?" "I want to try it in Tiananmen when the Chinese government holds a rally in Tiananmen." Bold tentatively threatened: "This is a risky behavior!" "Success is only possible if you take risks!" Bold immediately promised him: "Mr. Li Andong, if your plan is successful, we can give you 500,000 US dollars! After it is completed, the US Strategic Intelligence Agency can guarantee that you can go to America or Europe to engage in your own business freely. Be a millionaire!" This time, Boulder sent an action signal to Li Andong through Cheng Na under the instruction of Du Novan, the special agent chief of the US Strategic Intelligence Service. Zhe Li's arrival fulfilled Li Andong's dream.He took the half of the business card that Zhe Li took out from his jacket pocket, quickly took out an Italian book from the shelf, and took out the other half of the business card from the fold of the book cover, and carefully identified it under the inspection mirror with an optical device: " OK, the contact password is completely accurate!" Zhe Li approached and took a closer look: "Very reliable, it's Colonel Boulder's business card!" Li Andong's light blue eyes flashed fiercely, and he ordered: "You immediately tell Ryuichi Yamaguchi, and contact Tokyo right away!" In the evening, Ryuichi Yamaguchi drove towards Dongjiaomin Lane, and a few minutes later, he stopped at a street behind Dongjiaomin Lane.After getting off the car, he tucked his purse tightly under his arm and hurried into the "smoked fish shop" run by an Iraqi woman in the embassy district. Colonel and military attache of the US embassy in China, Paul Bold, often came and went with this woman when he was in Beijing.Boulder bought her with money for his professional needs, and she became the person who conveyed information for Boulder. Ryuichi Yamaguchi came to the Iraqi woman's house, and the two talked and laughed happily, with ambiguous words in their ears.After a while, Takaichi Yamaguchi handed her a bag: "This is 1,000 US dollars!" Then he took out a kraft paper letter: "I will send it by express at Dongdan International Post Office tomorrow morning!" The Iraqi woman readily agreed.Thus happened the scene at the beginning of this article. Director Li Guangxiang, who came back from Zhongnanhai, told Cao Chunzhi when he arrived at the Ministry of Public Security: "Comrade Peng Zhen has made a decision and asked to solve the case before the National Day. I think we will act tomorrow!" After Cao Chunzhi accepted the task, he immediately made arrangements: 1. Notify the Fifth Bureau to strengthen the defense measures of Tiananmen Square, ensure the security inspection of Tiananmen Square, and send more armed secret guards to guard Tiananmen Square, so as to prevent problems before they happen. 2. The investigators who monitor foreign spies are all replaced by experienced old investigators, and no mistakes are allowed at critical moments. 3. Postal inspection control and "deep special circumstances" have a common task, which is to continue to seize evidence. Yang Qiqing, deputy minister of the Ministry of Public Security, who had just returned to Beijing from another place, arrived at the investigation department as soon as he got off the car.After listening to a brief report on the progress of this major case, I was very happy, and instructed Director Li Guangxiang to say: "Immediately gather outstanding investigators from Beijing, Tianjin, Hebei, and Shenyang to the Ministry of Public Security to jointly participate in solving the case, and make an investigation before the National Day." The battle of annihilation, this is the best time to train a professional scouting team. Let those prophets who laugh at our ability to capture big cities but not be able to manage them feel sorry for themselves!" At 6:15 on September 28th, a crisp whistle sounded, and the scouts in full gear had assembled in high spirits. At 7 o'clock in the morning, Li Guoxiang arrived on time.He issued a combat order: After investigation, American imperialist spies attempted to bombard Tiananmen Square on National Day, murder the great leader Chairman Mao and other party and state leaders, and create international chaos.Accordingly, the Ministry of Public Security ordered: "Arrest Li Andong, Ryuichi Yamaguchi, Ganus, Zheli and other spies in accordance with the law!" Cao Chunzhi then announced the action plan: "First group, arrest Li Andong; second group, arrest Ryuichi Yamaguchi; third group, arrest Ganus; the deputy chief of the investigation department Cheng led the undergraduate field team to arrest Zhe Li." With "boom, boom, There was a sound of engine starting, and jeeps, trucks, and motorcycles roared towards the target. In the morning light, Ganyu Hutong in Beijing is peaceful.As if Ganus had a premonition, he suddenly felt inexplicable agitation and uneasiness.After thinking about it, he decided to go to Tianjin immediately and return to Germany via Hong Kong. Ganus hurriedly put on his suit, picked up the sky blue suitcase and ran to the yard, shouting loudly: "Driver! Driver! Drive!" The driver was prepared and said, "Where are we going? The car doesn't start well!" "What's the problem?" Ganus asked dissatisfied. "The exhaust pipe is blocked, and there is too much exhaust gas." The driver seemed a little panicked due to nervousness. Seeing the driver's attitude change, Ganus took out a silent pistol and aimed it at the driver's chest.Hearing a "whoosh", the investigator Li Wuhai, who was ambushing beside the car, kicked his pistol away, and then rushed forward and twisted his arm. Ganus was still in shock, and a pair of cold handcuffs had already been put on, "This is Tianjin you are going to, you are under arrest!" Ganus yelled loudly: "Who are you? How dare you break into our foreigner's house?" "We are investigators from the Ministry of Public Security of the People's Republic of China!" "I'm not guilty! I'm a legal immigrant, why should I be arrested!" "Since you have committed a heinous crime, don't even think about running away. Running away is a crime!" "I'm not guilty, I'm a businessman!" "The businessman is holding a murder weapon, and he still says he is innocent?" Ganus didn't know how to quibble for a while, so he was escorted into the car. For several days, Ryuichi Yamaguchi had an ominous premonition, constantly adjusting his emotions, praying to the gods to bless him to return to Japan safely... In the early morning, he was sitting quietly with his eyes closed, reciting scriptures, when suddenly there was a deafening motor sound outside the house, and he woke up. At this time, Wei Zhi ran in in panic: "It's not good, the Communist Party is here!" Subconsciously, Takashi Yamaguchi got up quickly and wanted to reach for the pistol on the desk, but was held down by the investigator Shen Jizong who rushed in. "You are under arrest!" Shen Jizong showed his arrest warrant. Ryuichi Yamaguchi tilted his head and shouted loudly: "I protest! What law have I committed?" "You know what letter you sent to Tokyo in the name of a businessman!" Ryuichi Yamaguchi was very frightened and thought: The investigators of the CCP are really good! Shen Jizong pointed out sharply: "You purchased high-range fire extinguishers in name, but actually reported to the intelligence office of the U.S. Allied Command in Tokyo the plan to bombard Tiananmen Square, as well as the carefully drawn topographic map of Tiananmen Square, in an attempt to murder Mao Zedong on the '11th'. Chairman and the leaders of our government, isn't this a crime?" Ryuichi Yamaguchi bowed his head in silence, his face turned yellow, and he never dreamed that their plot would be completely exposed. On September 28, Li Andong woke up very early. According to the plan, he should gather the disassembled and scattered mortar parts today and prepare for shooting. Early in the morning, he was going to drive to the "Holy See" in Naiz Mansion where the mortar parts were hidden.Just as he was about to leave, his concubine, Jia Salin, took his hand and said, "Just in case, let Ryuichi Yamaguchi and Zhe Li go get it, let them do a fake operation, and then you go get it yourself." "You are too careful!" Li Andong pushed his concubine's hand away. At this time, hurried footsteps came from outside the house. Li Andong's most trusted "handymen", that is, investigators Xin Lixue and Zhang Baoying sent by the public security department, pushed the door in. "Mr. Li Andong, we are investigators of the Ministry of Public Security of the People's Republic of China, and we are ordered to arrest you!" Li Andong was taken aback for a moment, and his hairy wrists were handcuffed.At the same time, Zheli also became a prisoner in the hidden residence. While the investigators were rejoicing at the successive arrests of the spies, Xin Lixue called from Li Andong's house and said anxiously: "Chief, Li Andong's family has not found any obvious criminal evidence!" Cao Chunzhi asked sharply, "What? No obvious criminal evidence was found? If you search carefully, I will lead the internal security team to arrive immediately!" Li Andong is the focus of solving the case this time. If no criminal evidence can be found, the matter is of great importance! Cao Chunzhi put on his military cap impatiently, and was about to set off. Just as he stepped in and out of the door, Han Fuguang, chief of the investigation section of the Baoding Public Security Bureau, came. "I heard that Director Cao is solving a big case again, let's take a look!" Han Fuguang was still in that high-spirited, cheerful manner, looking particularly affectionate.When Cao Chunzhi saw Han Fuguang, he turned his worries into joy and said, "Brother came just in time, what are you looking for? Don't talk about other things today, you will join the battle immediately! No obvious criminal evidence was found in the home of the main criminal Li Andong, so hurry to Li Andong The boss is going to be responsible for the on-site inspection!" Han Fuguang was surprised by the sudden mission: "Hey! Where are you?" "There are investigators leading you there, get in the car, go, go! I'll call right away, and you will be in charge of the scene!" The little car said like an arrow. Drive out of the gate of the Ministry of Public Security. When Han Fuguang arrived at the scene, the investigators were opening the three mahogany carved cabinets they had just found, which contained stacks of materials in foreign languages.Han Fuguang picked up a stack of materials and looked at them keenly, and said to Zhang Baoying: "Quickly find out the nature of the materials!" A large number of Italian materials need to be checked immediately.Han Fuguang called Cao Chunzhi: "Dude, I think it's an intelligence draft, please send another Italian translator, hurry up!" After random inspection and translation, Zhang Baoying said: "Most of these materials are information about our country's politics and military affairs, including the highly confidential "North China Air Force Base Information", "Siping Campaign Information", and "Jindong Iron Ore Resources Analysis". There are also the resumes, addresses, telephone numbers, and car numbers of the head of the Central People's Government, the chairman and members of the CPPCC National Committee, and the leaders of the democratic parties and people's organizations." "This is completely espionage!" After finishing speaking, Han Fuguang called Cao Chunzhi again: "As expected, after the translation inspection and identification, most of them are important political and military secrets of our country!" Cao Chunzhi happily replied: "Brother, Qianjun It’s easy to get, the hardest to get, it’s true..." Han Fuguang walked up to Li Andong, raised two sword eyebrows and said solemnly: "You are a businessman, why do you collect so much political and military information about China?" "This is your country's NEWS. It is completely legal for us foreigners to provide China's situation to the international public opinion. This is our freedom of the press. I don't understand what the political and military intelligence you mean?" "We Said, the news you posted is the important military information of our country, and there is no important military information publicly released!" "Sir, I don't know if you know that intelligence and news are the same concept and interpretation, and they are the same term in English." Li Andong thought that Han Fuguang didn't understand English, and deliberately made things difficult for him. The clever Zhang Baoying immediately refuted him in English: "Nonsense, the English word for news is 'NEWS', the word for intelligence is 'INTELLIGENCE', translated into Chinese as 'timely and secret report', the concept of news is different!" Unexpectedly, Li Andong ridiculed Zhang Baoying in a scholarly tone and said: "Miss, your explanation is too superficial." But he himself could not give any basis. Seeing that Li Andong was still unconvinced, Han Fuguang said gently: "Mr. Li Andong, we do not deny that information and secrets contain news value, or are easily reported as 'latest news'. However, since you said it is news , so which news agency or radio station did you send it to? Do you have any evidence from the news agency?" Li Andong still quibbled: "Publishing news about China to the outside world is our freedom of the press, and you have no right to interfere!" "How can it be said that there is no right to interfere? Our Central People's Government's Administrative Council's regulations on news release stipulate that those belonging to national defense, military and public security secrets, diplomatic and financial secrets shall not be published as news. I think every country has a strict control over news. Management will follow this principle!" "In the West, the press is free!" The investigators searched every corner that was considered easy to hide evidence with a keen eye. Li Andong's eyes showed disdain, as if to say, your search is futile.Because he knew that no matter what, no evidence of his crime had been caught.The Chinese government has always believed in evidence.Besides, the evidence was subtly dispersed and concealed as if by magic.As an outsider, no matter how powerful you are, it will be difficult to discover the secrets inside. Suddenly, an investigator from the Tianjin Municipal Public Security Bureau who came to help solve the case found a small iron box wrapped in oiled paper from Li Andong's bookshelf close to the ceiling.Due to lack of common knowledge about weapons, it was dismissed carelessly. Han Fuguang heard a muffled "clang" in the study, and immediately walked over vigilantly. When he was studying at Yan'an Anti-Japanese University, he had studied Chinese and foreign ordnance knowledge, and had special research on weapons.He picked it up, saw the Stokes letters on it, and immediately recognized it as a camouflaged Stokes mini-mortar barrel. He immediately called Cao Chunzhi to report the situation. Cao Chunzhi replied quietly and loudly: "Okay! You can continue to search and find evidence!" At the same time, investigators also launched a large-scale search in the Catholic Church in Naiz Prefecture.The investigators who were ordered to search knocked open the hall of the north room of the church shrouded in a solemn atmosphere.Ma Liyue was wearing a bishop's coat, and when she saw several investigators, she immediately asked in blunt Chinese, "Who are you looking for?" "What's your name?" the investigator asked back. "My name is Mali Yue, and I am the bishop here!" "We are from the Ministry of Public Security, and now we need to check your residence due to business needs." The investigator quickly showed the search warrant. Ma Liyue looked very unnatural, and refused to say in blunt Chinese: "This is a church, you are not allowed to violate the dignity of the church!" Ma Liyue stared at the visitor with a threatening tone. "Sorry, you have no right to refuse our inspection. You are in China and should abide by Chinese laws! This is also your responsibility!" Maliyue remained silent, gasped for breath, and squinted at the other party. Accompanied by the police and two members of the church, the investigators searched the north house and the west living room where Ma Liyue lived.Sure enough, weapons such as mortar mounts, gun mounts, and grenades were found hidden on the left side of the fireplace. The investigators immediately reported to the command post Cao Chunzhi: "We found gun mounts, gun mounts and other weapons in Maliyue Church." "Did you find the barrel?" "No!" "Immediately send the gun mounts and carriages to Li Andong's house for on-the-spot appraisal!" Just as Cao Chunzhi put down the phone, another phone rang. Investigator Shen Jizong of the field team dispatched to search the "Far East Fire Equipment Company" on Dongdan Avenue controlled by Li Andong reported at the scene: "Among the fire-fighting equipment in the warehouse, gun mounts, gun mounts, shells, etc. of the Stokes small mortar were found." Cao Chunzhi said excitedly, "I'll just wait for your words!" Then he asked, "Did you find the cannon barrel?" "No! The manager of the company claimed that the goods had already been sold, and put a shipping label on them, blocked the inspection unreasonably, and planned to take them away by force!" "It's nonsense! The matter is clear. You immediately send all the weapons to Li Andong's investigation site and hand them over to Comrade Han Fuguang!" The weapon that Li Andong was looking forward to arrived. When the scouts took out the gun mounts and carriages and carried them to the yard, Li Andong stepped forward in shock to stop them. Han Fuguang waved his hand: "Stop!" Immediately, Han Fuguang stepped forward to pick up the gun barrel and gun mount, clamped his legs skillfully, twisted and closed his hands, and only heard a burst of "cracking" metal impact, and quickly assembled a Stokes-type gun. Shotgun.Then, he placed more than a dozen cannonballs sideways, and asked angrily: "Mr. Li Andong, is this also NEWS? This is evidence of espionage!" Li Andong's legs trembled in fright, and he murmured, "This is..." "What is this?" Han Fuguang shouted. Li Andong's mental defense completely collapsed.The conspiracy of US imperialist spies to bomb Tiananmen Square was completely bankrupt. On August 17, 1951, the Military Law Division of the Beijing Military Control Commission of the Chinese People's Liberation Army made a verdict on this case, and the principal culprits, Li Andong and Yamaguchi Ryuichi, were sentenced to death.Ganus and Zheli were sentenced to fixed-term imprisonment and were deported after serving their sentences.
