On this day, 120 years ago, on March 10, 1905 (February 5, 1905), the red agent Hu Di was born. Hu Di, a revolutionary martyr, served as an outstanding intelligence officer of the Special Branch of the Central Committee of the Communist Party of China. Together with Qian Zhuangfei and Li Kenong, he broke into Chiang Kai-shek's top spy agency, the Party Affairs Investigation Department of the Central Party Department of the Kuomintang. Risking his life, he went deep into the Longtan and Tiger's Den and passed on a large number of confidential intelligence of the enemy. In recognition of their great wisdom and bravery, Zhou Enlai once praised the "Three Heroes of Longtan". Li Kenong said: "Hu Di is the youngest, but his literary talent is the highest." In 1935, the Red Army was brutally killed by Zhang Guotao during the Long March. He was only 30 years old. Hu Di was born on March 10, 1905 in a family of industrialists and landowners in Songyuan Village, Xinjie, Ganchahe Town, Shucheng County, Anhui Province. His original name was Hu Baichang; aliases include Bei Feng, Hu Ma, Shang Tian, Yi Yu Hu Di, etc. He attended a private school with his uncle Hu Jizhang when he was young, and entered Shucheng Chengguan Plant-planting Primary School at the age of 15. In 1921, before graduating from high school, Hu Di was admitted to Hefei Provincial No. 2 Middle School with honors. In 1923, just after entering middle school for two years, he was admitted to the Chinese University in Beijing. In 1924, Hu Di met Qian Zhuangfei at the Anhui Guild Hall in Beijing after being introduced by a classmate, Wu Luming. Qian Zhuangfei and his wife were studying at the Beijing Medical College at the time, and the two have been close friends since then. At that time, Qian Zhuangfei lived in Pinganli, Xicheng, Beijing, and Hu Di often came to talk. In 1925, he joined the Communist Party of China with Qian Zhuangfei and Zhang Zhenhua. In 1926, after graduating from Chinese university, he lived in the Qian family. In 1926, Qian Zhuangfei, Hu Di and Xu Guanghua co-founded a film company - "Guanghua Film Company". "Yanshan Heroic Hidden", which was shot at that time, was an early feature film in our country and was once sent to Japan for screening. Hu Di and Qian Zhuangfei's family went into battle as actors. Qian Zhuangfei's 11-year-old daughter, Zhen Zhen, also played a role in the film, and the father and daughter performed on the same stage. Later, Zhen Zhen changed her name to Li Lili. At that time, they played the roles in the film while using it to cover the secret work of the party. In 1927, Chiang Kai-shek staged a "412" counter-revolutionary coup. On April 28, Li Dazhao was killed by Zhang Zuolin in Beijing. Hu Di and Qian Zhuangfei were also blacklisted by the enemy and wanted by the reactionary government. Hu Di immediately changed his name to Hu Ma, which was "Beifeng"; Qian Zhuangfei and he changed their names at the same time and became "Nanfei". This winter, they left Beijing together and moved to Shanghai. In the spring of 1928, Hu Di applied for a job at the Shanghai Film Company in order to make a living. By then, Qian Zhuangfei had already entered the Shanghai Radio Administration, where Xu En had served as director, and was trusted by Xu. Qian Zhuangfei has been increasingly trusted since he was admitted to the radio training class run by Xu Enzeng in 1928. In the autumn of 1928, after Xu Enzeng was appointed by Chiang Kai-shek as the director of the Shanghai Radio Administration, he kept Qian Zhuangfei by his side as the secretary of the bureau and later served as Xu's personal secretary. Xu was a close confidant of Chen Guofu and Chen Lifu, the leaders of the Kuomintang's C.C. system. The so-called radio training class and radio administration were actually the Kuomintang's secret service. When Qian Zhuangfei learned this, he wanted to talk to the party organization about the situation, hoping to get instructions from the senior party leaders: How should he deal with it here? At this time, Li Kenong, who went by the alias Li Zetian, served as a propaganda committee member of the Shanghai Central District Committee of the Communist Party of China. One day, I suddenly met Hu Di in the studio of a film company. They were fellow villagers from Anhui, who had known each other in Wuhu and participated in revolutionary activities together. After Hu Di's arrangement, one night in early November this year. Qian Zhuangfei and Li Kenong met in the studio of Hu Di. After listening to Qian Zhuangfei's detailed account of this experience, Li Kenong said that it is really difficult for you to deal with it alone. Is there any way to wedge a nail in it? Qian Zhuangfei thought about it and said. There is a good opportunity in front of you: the Shanghai Radio Administration is recruiting and expanding its staff. Now there is a shortage of broadcast news editors, so it is necessary to recruit openly. I hope the party organization will take advantage of this opportunity to send people into the Shanghai Radio Administration. Li Kenong reported the relevant situation to the Central Committee of the Communist Party of China through the Jiangsu Provincial Committee of the Communist Party of China, and put forward his willingness to apply for the Kuomintang Radio Administration. And Qian Zhuangfei and Hu Di proposed to establish a special team of the Communist Party in the Kuomintang secret service agency. Zhou Enlai agreed to Li Kenong's suggestion. After Qian Zhuangfei arranged, Li Kenong, after careful preparation, broke through several hurdles with excellent results, and was admitted to the Shanghai Radio Administration in December, and was appointed as the broadcast news editor of the bureau. Soon, after Qian Zhuangfei introduced, Hu Di also joined the Shanghai Radio Administration. In December 1929, Chen Lifu planned to establish an anti-communist spy agency for secret reconnaissance and interrogation on the basis of the Party Affairs Investigation Department of the Kuomintang Central Party Department, and instructed Xu Enzeng to handle this matter. As soon as Xu Enzeng took office in Nanjing, he immediately entrusted Qian Zhuangfei to organize a secret command organ in Nanjing in the name of his confidential secretary. At this time, according to the instructions of the Central Special Committee, Li Kenong and Hu Di also took this opportunity to break into the top secret service of the Kuomintang. In the second half of 1930, Hu Di was sent to Tianjin to build the Great Wall News Agency. This was the branch of the Kuomintang secret service in the north, under the jurisdiction of the Nanjing Yangtze River News Agency. Hu Di served as the president of the bureau. Every time there was urgent information in Nanjing and Tianjin, Qian Zhuangfei and Hu Di immediately reported it to Li Kenong in Shanghai, and Li Kenong passed it on to the Central Committee of the Communist Party of China through Chen Geng in a timely manner. In April 1931, Gu Shunzhang was arrested and defected. He Chengjun, the director of the Wuhan camp of the Kuomintang, and the secret service agency continuously reported Gu Shunzhang's defection telegrams to Chiang Kai-shek and Xu Enzeng. On the night of April 25, Qian Zhuangfei was intercepted in the "base camp" of the investigation department; he immediately sent people to Shanghai to report to the Central Committee of the Communist Party of China. After Zhou Enlai, Chen Yun and other leaders took emergency measures, the leaders of the Central Committee of the Communist Party of China, the Jiangsu Provincial Committee of the Central Committee of the Communist Party of the Communist Party of China, and the organs of the Communist International in Shanghai were all quickly transferred safely, so that the party organization could avoid a catastrophe. At this time, Hu Di was still in Tianjin. On the night of learning of Gu Shunzhang's defection, Li Kenong sent Hu Di a telegram This is the code they agreed in advance: "Ke" means Li Kenong, "Chao" means Qian Zhuangfei's alias Qian Chao, and "Sick" means that the situation is serious and must be acted immediately. Hu Di received a telegram and left Tianjin on a foreign ship. After Hu Di left Tianjin, in the early morning of April 30, Kuomintang spies colluded with the Japanese Concession to rush to the Great Wall News Agency to search for him. At that time, Li Kenong and Qian Zhuangfei, who had infiltrated Shanghai from Nanjing, had already hidden themselves in the Zhabei area of Shanghai. Hu Di and Qian Zhuangfei left Shanghai together in August 1931 for the Central Soviet Area, and Li Kenong arrived in the Central Soviet Area a little later. After entering the Soviet Area, they have been serving as political security work. Li Kenong served as the director of national security, Qian Zhuangfei served as the director of the political security bureau of the Red Army on the First Front, and Hu Di served as the head of the interrogation section of the executive department of the National Political Security Bureau. In October 1934, after the Central Red Army began the Long March, Hu Di served as the head of the reconnaissance section of the Central Military Commission. On June 12, 1935, the Red Army and the Red Fourth Front met in the Dawei area of Maogong, Sichuan. In August, the Red Army headquarters divided the Red Army into left and right armies to go north. The commander-in-chief of the Red Army, Zhu De, the general political commissar Zhang Guotao, and the chief of the general staff, Liu Bocheng, followed the left army in action. However, after the Left Route Army arrived in the Aba area, Zhang Guotao suddenly ordered all the Left Route Army and a part of the Right Route Army to go south and split with the Party Central Committee. Hu Di, who worked with Zhu De and Liu Bocheng in the Left Route Army, was very dissatisfied with Zhang Guotao's separatist behavior and often expressed his resentment on some occasions. When Zhang Guotao learned of this, he became angry and framed him, Li Kenong and Qian Zhuangfei as "Kuomintang spies", gave him the hat of "counter-revolution", strictly controlled him, cancelled his horse and attendants, and forced him to march with a backpack and "wear a crime" when he was sick. In September of this year, when he walked between Starba and Songgang, Zhang Guotao ordered him to be killed. Comments: In the history of the CCP's covert front struggle, there are former and later "three heroes", known as the "first three heroes" referring to Li Kenong, Qian Zhuangfei, and Hu Di, and the "last three heroes" referring to Xiong Xianghui, Chen Zhongjing, and Shen Jian. This statement comes from Zhou Enlai, the leader of the CCP's covert front, which can be said to represent the evaluation of their contributions by the CCP's high-level.
