I want to say one thing here. In 1980s, the defection of Yu, the director of the Security Bureau, directly led to the arrest of Jin Wuji, the most outstanding spy in China who had been lurking in the United States for more than 40 years. At that time, Kim was the director of the East Asian Policy Research Office of the United States. He not only provided a decisive research report for the US government's decision on China, but also gave top secret information such as the US government's China policy and bottom line to China, which allowed me to take my time in diplomacy and take the initiative. King's arrest is the biggest loss in China's intelligence war against the United States. Three years later, Kim committed a bizarre suicide in prison. After all these years, I can tell the truth now. Jin Wuji is a spy personally controlled by the leader of the Ministry of National Security. He can't get in touch with Jin with Yu Johnson's secret classification, but Yu is the secretary of the former minister. He inferred the gold by going to the minister's office to read the files, and then gave it to the United States as a defected gift. However, the traitor did not come to a good end after all, and the Ministry of National Security of China launched a global hunt. Although Yu was nominally protected by the US government, he was chased by five secret agents in South America and drowned in the sea two years later. Later, the battalion chief who commanded the operation was promoted to an important position.
