Seeing this, some of the content on the intelligence has even begun to appear after Pu Su arrived in Shanghai. Obviously, the intelligence work in the border region did not relax because of the situation, but collected all the useful information as much as possible.

On March 30, 1940, Wang Wei formally established a new puppet government in Nanjing. The struggle for power was nominally held by Wang's uncontrolled "orthodox" Kuomintang, whose No. 2 figure was Zhou Huhai. He has five different titles: Vice-President of the Executive Yuan, Minister of Finance, Minister of Police, Vice-Chairman of the Military Council, and Governor of the Central Reserve Bank. In addition, Zhou Huhai is also in charge of the secret police.

Educated in a good Japanese middle school and university, and graduated from Kyoto Imperial University in 1924, he chose to run the Kuomintang Propaganda Department in Guangzhou, as soon as he arrived in his homeland, where he had helped create China. This position also meant teaching the political research class of the Whampoa Military Academy, and he thus became a "tricky role" under Chang Kaishen.

After narrowly escaping the purge of 1927, Zhou Huhai, as editor of the monthly magazine New Life, theorized Sun Yat-sen's work and wrote the book The Theoretical System of the Three People's Principles (1918). This book was translated into Japanese by Ken Inukai. Zhou Huhai thus established a reputation among the Japanese intelligentsia.

At the end of 1939, before the official establishment of the Nanjing government, Zhou Huhai began to recruit and train personnel in Shanghai, so it was already quite noticeable when the new puppet regime was formally established on March 30, 1940.

In response to its birth, the New Gazette has long since taken on a new tone, criticizing the authorities in the two concessions for failing to stop the Chongqing authorities from hiring "terrorists" who are trying to obstruct the "further development of the peace movement."

This false report denounced Chang Kaishen's "lackeys" and the fact that people only shouted about recovering the concession, but in fact achieved nothing. The newspaper stated: "A new central government has now been born. Not only is our government anxious to regain China's concessions, but our friend, Japan, has also expressed its desire to help China recover these concessions......"

The actions of the secret service headquarters at 76 Extreme Fielder Road have failed the claims of peaceful police management of the land, and on the other hand, blurred a line that Wang's supporters wanted to draw.

That is, the line between opportunistic "bad" collaborators like the members of the new government of Liang Hongzhi and idealistic "good" collaborators like them.

The latter cooperated with Japan, supposedly to "achieve peace and protect the Chinese people." Later, a political commentator commented

In the past, Wang Kemin's "Provisional Government" and Liang Hongzhi's "Restoration Government" were both treacherous old-timers, and the people in the occupied areas called them "Qianhan"! And the puppet mansion of the former Wang Wei is naturally called the "Later Han"!

Many traitors often verbally admit that they are "post-Han" and are not ashamed of it. Since the "Later Han" generation of the "former Han" was the puppet of the Japanese, everyone gritted their teeth and hated it, because the former was far inferior to the latter and was very evil, and the latter had No. 76 (pseudo-secret service), which was a murderous devil's cave, and everyone talked about the tiger's color.

Wang Wei's deputy, Zhou Huhai, may be the top head of the pseudo-secret police, but the real power in this horror cave is in the hands of Li Shiqun and Ding Mocun, two mutineers who worked in the Kuomintang intelligence service but defected to the Japanese and betrayed their new masters of secret agents.

Li Shiqun turned out to be an agent of the Statistical Survey Bureau of the Central Committee of the Chinese Kuomintang. Chen Lifu was appointed as the leader of the special team in Shanghai. Later, the Central Union sent him to serve in Jiangxi, a position he gave up in 1938 and went to Hong Kong.

In Hong Kong, he had a relationship with the Japanese consul general, Nakamura. This person introduced him to Clerk Shimizu. As a result, Li Shiqun began to collect intelligence for the Japanese in the late summer of 1938.

Li Shiqun has excellent interpersonal relationships in Shanghai. He joined the Green Gang in the early twenties and became Ji Yunqing's apprentice. Upon his return to Shanghai in the fall, Li quickly realized that he could use his position as an official in the Central Committee to gain intelligence and agents.

In order to develop from a small intelligence gathering agency to a large gang of profit-seeking people, engaged in spy activities for Japan. Through Wang Manzuo, a former member of the Kuomintang Municipal Committee and Boss Du's apprentice, he gave Boss Du a huge police file of Du Yuexiao stolen by the Japanese from Hong Kong, thus winning Du's favor.

Li Shiqun also quickly recruited seven former agents of the Central Committee and members of the department to form a core as his backbone. In addition, he won the loyal service of "another member of the Green Gang, Wu Shibao, who recruited local gangsters to serve as Wang's guards, as well as other active collaborators.

Wu Shibao is a swarthy and stocky sadist, and his wife is a Shanghai beauty who is known for her ruthlessness.

In 1933, Ding Mochun had been the editor of the Shanghai-based publication Social News, where he had supervised Li Shiqun's work, and he had a higher position in Chen Lifu's Central Bureau, serving as director of the Third Division until 1938, when the department was reorganized and Daly took over.

At that time, "Ding Xiaogui" (he was only five feet tall) was ostensibly no longer engaged in intelligence work, but had another position in Hankow. According to Chen Lifu's own account, Chang suspected that Ding Mo Estate had committed treachery because Daley had intercepted a telegram from Ding Mo Estate and "a Japanese in Shanghai". However, when the commander-in-chief suggested that Chen Lifu arrest Ding Mo Chuen, Chen Lifu replied that Ding had reported to him about his contacts with the Japanese. Chang Kaishen only briefly approved the word "read" on the memo and returned it to Chen Lifu.

Shortly thereafter, Ting Mochun went to Hong Kong without permission. Chang Kaishen reprimanded Chen Lifu for not letting Ding Mochun leave, and asked him who was the introducer of Ding Mocun's party membership. When Chen Lifu replied that it was Dai Jitao and Zhou Huhai, Chang Kaishen stopped gnawing except for saying "I have to be on guard".

(Twenty years later, Chen recalls that the president was completely right.) "After Ding Mocun arrived in Shanghai, he destroyed the military command and the Central Unification Organization")

At the beginning of 1939, Li Shiqun invited Ding Mochun to Shanghai. After he arrived in Shanghai, the two of them went to the Japanese secret service in Hongkou to visit General Kenji Dohihara. As previously noted, Chen's assassination had convinced the Japanese that they had to create their own Chinese secret service to protect high-ranking collaborators such as Wang Wei.

In Shanghai, the specific job of Ding Mochun and Li Shiqun was to help "gather a group of Kuomintang comrades to advance "peace". Because of the addition of the two of them, the Japanese were glad to have gained the means to infiltrate what had otherwise seemed to be an impregnable Chinese social network.

In order to entrap these two people, they can make better use of the "complex personal relationships in Chinese society" that Chongqing agents have developed so well. Doihara strongly recommended and supported the plan to establish a pseudo-secret service, which was approved by the General Staff of the Army in Tokyo on February 10, 1939.

As a result, Li Shiqun and Ding Mochun officially started their activities on March 1. Qingqi Daisa was appointed as their liaison officer with the Mei agency and the military intelligence agency of the Ying Zuo Zhao Daisa, who supervised the Wang Wei Nanjing government. Ding Mochun and Li Shiqun agreed to explain the details of the operation to the Japanese gendarmerie in advance and to submit information on a daily basis. In return, they receive fixed weapons, ammunition, and monetary support.

Soon after their activities at No. 76 Jisifeier Road, the combination of Li and Ding facilitated the mutiny of key military agents such as Wang Mutian and Chen Mingchu, and also destroyed their secret service organizations. It should have been Chen Mingchu who exposed some of the assassins to the Japanese consular police, and the Japanese later handed over Xu Enzuo and them to Wang's puppet secret service.

On February 19, 1939, a few days after Chen Zheng was killed, Xu Guoqi, one of the leaders of the military commander's assassination team, was arranged to leave Shanghai and go to Hong Kong's safe harbor together with Ping Fuchang and You Pinshan, and his ship departed on February 28.

Zhu Shanping warned Tan Baoyi that Shanghai was too dangerous, and then gave him 80 yuan to buy a ferry ticket. The ship departed 20 days later and arrived in Hong Kong on March 15. Xu Guoqi received instructions from Tan Baoyi's cousin to book a room at the Diners Hotel.

The next day, he was taken to a luncheon at the Golden Dragon Hotel. Other members of the assassination team, Ping Fuchang, You Pinshan, and Zhao Guangyi, were also present. The host is a man about 1.68 meters tall and nearly 40 years old, and this person is Daley.

Although Zhao Guangyi later received Daley's reward and was praised as a national hero who killed Chen Zheng. However, when Dai Li met with them, he did not mention anything about the assassination of Chen Qi. Dai was accompanied by two lieutenants. Dai Li gave each of them a fountain pen worth 20 yuan and encouraged them to work hard. This was the first and last time that Ping Fuchang and Tan Baoyi saw their secret agent leader.

Tan Baoyi and his military colleagues Ping Fuchang, Zhu Shanqiu, and You Pinshan spent two months in Hong Kong, waiting for a new mission. At the end of May 1939, Zhao Guangyi finally gave them a new order to return to Shanghai, under the command of Mao Wanli and Wang Luzhao, and prepare to assassinate Wang Jingwei.

The group then returned to Shanghai by way, with the four agents on the same boat and the two leaders on the other boat. When the agents arrived in Shanghai on June 1, they rented a room at the Xiating Apartment at 66 Baier Road, while the two chiefs stayed at the Dazhong Hotel and the Dafang Hotel, respectively.

At 5 a.m. on 29 June, Cao Chang Kaden and another Japanese military police officer went to the city branch of the Police Department of the Ministry of Industry Bureau, claiming that they had obtained information that two members of Chen Zheng's assassination team were living in room No. 24 of Xia Fei's apartment. They did not disclose the source of this information, but said that the information was very reliable and could have been carried out in a surprise search.

After the inspectors of the police department of the Ministry of Industry Bureau agreed to cooperate, they went to Lujiawan in the concession with the two Japanese military policemen to arrest houses, and after obtaining the consent of the inspector Delome, they took joint action. As a result, a joint force of Japanese and British police officers left for Tan Baoyi and Pingfuchang's apartment shortly after dawn that morning.

Without any suspense, after Tan Baoyi and Ping Fuchang were arrested on June 29, the police seized firearms and ammunition in room 14. However, the Police Department of the Ministry of Works, which had the right to interrogate the two prisoners, was initially unable to get them to admit that they had done anything bad.

At a formal interrogation the next day, the two secret agents insisted that they had no connection to the Kuomintang government

However, Japan's consular police and gendarmes were convinced that the information they had obtained was correct and believed that the two men were indeed involved in the assassination of Foreign Minister Chen Zheng.

On July 3, 1939, Kaden Tian submitted a formal request to the Police Department of the Ministry of Industry and Bureau, requesting that Tan Baoyi and Heap Fuchang be extradited to the Japanese gendarmerie for interrogation.

The Ministry of Industry and the police were in no hurry to agree, as the institution where Mr. Gaden Tian Cao worked was already notorious for mistreating prisoners, especially when it came to suspects in the Chen Zheng case.

For example, on March 16, 1939, the Police Department of the Ministry of Industry was asked to assist Chief Cao of Kaden Tian in arresting Shao Fusheng, the guard who had left his post at the front door of his mansion on the night Chen Zheng was killed.

Gadentian acted according to the usual anonymous intelligence. In this case, the secret information was obtained from a complex transaction involving a loan fraudster, a theatre owner and two former police officers.

One of the two ex-police officers is a former Chinese detective who worked at the Gordon Road arrest house. This person is the co-owner of the Diners Club, where Shao Fusheng used to work as a ticket collector. He recommended Shao Fusheng to Wu Tiecheng's secretary and served as the night doorman of Chen Zheng's mansion.

The deal between them did not go well, and there were more than one brawls due to the fact that the borrowed money was not repaid. Finally, one of the participants reported to the Japanese gendarmerie about Shao Fusheng's whereabouts. He also wore Chinese-style clothes and accompanied the police officers of the Police Department of the Ministry of Industry to Guizhou Road to identify the suspect.

At 3 o'clock in the afternoon of the same day, the Japanese military police found Shao Fusheng walking on the street near the intersection of Xiamen Road, and they asked the police officer of the Police Department of the Ministry of Industry Bureau, who had gone to arrest him, to identify him.

Kaden Tian Cao Chang was apparently convinced that Shao Fusheng was a member of the assassination team. But the agents of the Ministry of Industry and Police's police department were not so convinced, especially when his confessions about his whereabouts on February 19 (such as having morning tea at a bookstore, collecting tickets at the Diners Theater in the afternoon, etc.) coincided with the confessions of independent witnesses.

However, even though the Ministry of Industry and Bureau police were fairly sure that Shao Fusheng was innocent, they handed him over to Kaden Tian for a three-day interrogation (from March 21 to March 24). The interrogation period was later changed from three days to four days — what appears to be a long time.

On the afternoon of the first day, Gadentian and his gendarmes took Shao Fusheng across the Waibaidu Bridge (Sigh Bridge) and escorted him into the bridge building. He was taken into a room on the fifth floor, where the three Japanese began to torture him, especially when he denied knowing anything about Chen's case.

"I still deny that I know about the case. In the end, they tied me to a bench and poured cold water into my nostrils for about half an hour." - Shao Fusheng

After that, Shao Fusheng spent the night in a basement with the captured guerrillas. The next day, he was taken back to the interrogation room on the fifth floor, where he was harshly interrogated, but not tortured. On the third day, he was taken to another interrogation room on the sixth floor, where, in addition to the three Japanese, a Chinese agent from the Ministry of Industry Bureau was also involved, and he threatened to shoot Shao Fusheng if he did not tell the truth.
