On this day, 51 years ago, on January 15, 1974 (December 23, 1973, the "Li Hongshu Case" was revealed. Li Hongshu Case According to reports in "History of the Party", in the 1970s, the famous film "Bear's Trace" was filmed based on the "Li Hongshu Case" in 1974. In the 1970s, a large number of Soviet diplomats, under the command of KGB Chairman Andropov, engaged in espionage work abroad. On the evening of January 15, 1974, the First Secretary of the Soviet Union in China and Li Hongshu, a special agent sent by the Soviet Union to our country, and his accomplices, were captured by the public security organs and militia while exchanging intelligence. This also became the most famous spy case cracked in China in the 1970s. Spy Li Hongshu Marchenko In the autumn of 1972, when Xinjiang border guards were patrolling, they found empty cans of food they had just eaten on our side of the border and reported them to the Ministry of Public Security. The Ministry of Public Security immediately notified the public security departments of all provinces and municipalities across the country of the situation, and asked hotels, restaurants, and transportation stations in various places to pay attention to the investigation of spies who had sneaked into the Soviet Union. Soon, a man named Li Hongshu was found in a small hotel in Changchun City, Jilin Province. After interrogation, Li was from Heilongjiang. He was about 30 years old. He was a primary school teacher. He secretly crossed the border to the Soviet Union in 1967. He went to Moscow in 1970. He received special agent training at the Military Intelligence Agency of the Soviet Ministry of Defense. In June 1972, he accepted a dispatch mission and crossed the border from the Estuary of the Ertysh River in Xinjiang back to China. According to Li, he had been to Beijing, had contacted the Soviet Embassy twice, and then went to Changchun. After investigating Li's basic situation, this person was sent by the Changchun City Public Security Bureau to the Beijing City Public Security Bureau. The First Bureau of the Ministry of Public Security was responsible for it and decided to use him backwards after education. After Li Hongshu was detained by the Beijing City Public Security Bureau, he contacted the Soviet Embassy under our control. During the second contact, we observed through night vision that people had arrived at the Soviet Embassy, confirming Li Hongshu's explanation. Then, under our arrangement, Li Hongshu used a secret method to ask the KGB to send it to the radio station, and the Soviet side agreed to give it. The radio station was placed near Xiangshan Mountain, buried underground, and marked. Li took it under our surveillance. When he took it, he dug out a cement box and opened it to see that it was a radio station and 1000 RMB. This radio station was relatively advanced at that time. It recorded the sound on a tape in advance and emitted it as soon as a button was pressed. During this period, Li Hongshu escaped due to lax supervision. Li Hongshu ran to the suburbs and stole sweet potatoes to eat, but was taken back by his fellow villagers. On the evening of January 15, 1974, the central government decided to arrest Li Hongshu, that is, to stop the reverse use. Before arrest, Li Hongshu was asked to contact the Soviet Embassy and meet under the Xiba River Bridge. Wu Zhong, commander of the Beijing Garrison Command, ordered plainclothes police officers to lay ambush around the Xiba River. When Li Hongshu made contact with the Soviet Embassy personnel, plainclothes immediately surrounded him and he was captured red-handed. A small radio station that quickly sends and receives messages, secret instructions and secret developers, forged blank border passes, activity funds, etc. were seized. A car was seized on the spot with five people including the First Secretary of the Soviet Embassy. They were taken to the Public Security Bureau, and then the embassy people were released. These men were deported on January 19, 1974. The incident was publicly reported at that time, exposing the fact that the Soviet Embassy was conducting espionage activities in China. Chairman Mao said in a speech that we have achieved two victories: the victory in the border defense of Zhenbao Island in the north; and the victory in seizing the secret agents of the Soviet Union in the south. Stealing national military secrets has entered the era of peace. Our country has also captured many foreign spies of all kinds. They are mainly engaged in stealing military and economic secrets. An overseas spy named "Brother Fei" also revolted more than 40 people in China and stole national military secrets. Many Japanese spies active in China were also arrested one after another. The China government has a firm attitude towards spies who undermine national security. In 2014, China promulgated the Counter-Espionage Law, which clarified the legal definition of espionage for the first time. Espionage carries a maximum penalty of death. In April 2017, the "Reward Measures for Citizens for Reporting Espionage Clues" formulated by the Beijing City National Security Bureau was officially announced and implemented. The "Measures" stipulate that citizens who report espionage to the Municipal National Security Bureau can receive a reward of up to 500,000 yuan. It seems that this battle without smoke will not stop at any time.
