In the early morning of April 28, 1931, throughout The city of Shanghai, the enemy party launched a secret large-scale search, and a large number of armed military police and secret agents accurately found the addresses of Vice Chairman Zhou and others and rushed into more than a dozen red underground organs. Our underground organization is facing the disaster of extinction.
However, to the surprise of the military and police agents, after they rushed into the room, they found that everyone was empty, the antenna of the transmitter had not yet been dismantled, and the archives were burned in the brazier, indicating that the people had left not long ago. Chen Lifu slapped his thigh violently, angrily: "Hurry up and chase!" Only five minutes away! ”

Vice Chairman Zhou was leading the work of The Special Branch at that time
Shanghai's underground organs are very secretive, how can they be accurately found by the enemy? There must be a rebellion among our personnel! So how did Vice Chairman Zhou get the news in advance and escape the day?
At the beginning of April, Gu Shunzhang, the main person in charge of Special Branch, was given the task of escorting Chairman Zhang and Chen Changhao to the Eyu-Anhui Su District to do things, and subsequently, Gu Shunzhang's nature of liking to spend days and wine was difficult to move. Under the pseudonym "Dawn", he went to the dance hall to find fun, and also took the stage to show off the magic he learned. Unfortunately, the secret agent You Chongxin was also present, recognized Gu Shunzhang, and joined forces with several people to arrest him, directly escorting him to Cai Mengjian, the director of the investigation department. At the beginning, Cai Mengjian did not simply torture Gu Shunzhang to extract a confession, he knew that Gu Shunzhang controlled the list of personnel, institutional addresses and relationships of all underground organizations in Shanghai, and once he was recruited, he would definitely be able to promote himself to a high official and make a fortune.
At the beginning, Gu Shunzhang's attitude was unusually calm, and he did not reveal any information. In fact, his rebellious heart has a long history, and he has long envied the life of a drunken fan. There was a reason why he did not disclose intelligence to Cai Mengjian. He made two demands:
First, he wanted to fly directly to Nanjing and talk directly with Mr. Jiang, who was in a high position of authority and held so much important information, and Cai Mengjian's position was too low to speak to himself.
As one of the main members of Teco, Gu Shunzhang has a large amount of top-secret intelligence and has been called "the most dangerous traitor"
Gu Shunzhang, who arrived in Nanjing to meet the old Chiang Kai-shek, brazenly confessed all the information he knew about the Shanghai underground organization. Fortunately, the 6 secret telegrams sent by Cai Mengjian became the key message to save the underground organization!
Gu Shunzhang was right, the "Three Masters of Longtan" were the red agents lurking in the enemy camp. Among them, the talented Qian Zhuangfei was the first to enter the Central Bureau of Statistics, and was deeply appreciated by his fellow boss Xu Enzeng, and many documents were first let Qian Zhuangfei look over and then review them himself. He even went out to spend a lot of time drinking, and he temporarily stored the top secret codebook in the lockbox and shared a room with Qian Zhuangfei. And deciphering the code is not so difficult for a top agent like Qian Zhuangfei. He memorized everything in it at the first time to facilitate subsequent translation of information.
"Longtan Sanjie", the middle one is Li Kenong. The other two, Qian Zhuangfei and Hu Di, were sacrificed during the Long March
Later, in accordance with Vice Chairman Zhou's instructions, Qian Zhuangfei introduced Li Kenong and Hu Di to infiltrate the shanghai and Tianjin special agent unit chiefs together through the test. These three men went deep into the Dragon Pond Tiger's Den, cooperated with each other to intercept intelligence, and formed an iron triangle that broke into the enemy camp, and was praised by Vice Chairman Zhou as the "Three Masters of Longtan.".
On April 25, 1931, because it was a weekend, Xu En, then the section chief, went on vacation in Shanghai, and it happened to be his confidential secretary Qian Zhuangfei. He was alone in the office, calmly deciphering the first confidential information, and when he looked at the contents, after a brief surprise, his brain immediately moved at high speed: the content of the first secret letter was that Li Ming (Gu Shunzhang) was arrested and surrendered in Wuhan, and once he said the confidential information, if the agents sent troops fast enough, they could destroy the underground organization within three days. If this intelligence is true, it means that the Shanghai underground is facing a pot of threats. And the Shanghai side is still completely unaware, the situation has reached a moment of a thousand guns, leaving little time for themselves!
Xu Enzeng
Immediately after the second and third telegrams marked "Xu Enzeng personally translated" were sent, he did not hesitate to take it apart and decipher the relevant contents one by one: Gu Shunzhang would be transported by steamship, and if conditions permitted, it was possible to change it to an airplane. The next few letters are all nonsense asking for no rumors and credit. Qian Zhuangfei was only slightly relieved, if it was transported by ship, then there was still a chance to send out intelligence!
Chen Geng of the Teko period
Vice Chairman Zhou received the information provided by the "Three Masters of Longtan", reacted quickly, and immediately deployed: cut off all the clues that Qian Shunzhang said, cancel the joint code, and the hiding place, organize the emergency evacuation of all personnel, and take away the archives and documents, and those that cannot be taken away must be dealt with in a timely manner.
On the night of April 27, all the organs in Shanghai were evacuated urgently, all the underground traffic stations were transferred, and the cadres who were transferred together were Deng Political Commissar, Nie Rongzhen, Deng Yingchao and others. In the early morning of April 28, three days after Gu Shunzhang was arrested and defected, Vice Chairman Zhou arranged all the affairs and finally withdrew with Chen Geng. Disguised as an old man and woman in a hurry, they escaped the search of the agents and escaped in a thrilling way. The excellent work of the "Longtan Sanjie" allowed the Shanghai underground organization to avoid a huge disaster. Vice Chairman Zhou has praised many times that if it were not for Qian Zhuangfei, Li Kenong and Hu Di, we in Shanghai might not be alive, and history would have been rewritten.
Afterwards, Qian Zhuangfei was keenly aware that he was likely to be exposed, so he methodically restored the six telegrams to their original positions, and left a note that said, Do not hurt Qian Zhuangfei's family, otherwise Xu En's bribery will be revealed. When Xu En saw this note, he was ashamed and angry: "The most regrettable thing in this life is to reuse him!" ”
At this time, Qian Zhuangfei was already on his way to the Su District.
