Woven a spy network with footprints all over the national army general staff headquarters, the navy department and the military and political department. In order to cooperate with the Japanese attack on Nanjing, in mid-July, 1937, Yunzinan disguised as an employee of China Bank and sneaked into Nanjing among the refugees. She quickly turned Huang Xun, Secretary-General of the Executive Yuan of the National Government, and Huang Sheng, son of Huang Xun, Vice Foreign Minister, into spies.
At the beginning of the Anti-Japanese War, the Japanese government ordered Japanese spies lurking in China to assassinate Chiang Kai-shek in order to subdue Chiang Kai-shek and the National Government in one fell swoop.
The day before the August 13th Anti-Japanese War broke out, Chiang Kai-shek suddenly instructed the Central Military Academy to hold activities. Just as the participants lined up neatly, waiting for Chiang Kai-shek to speak, Japanese official Huiji suddenly announced to everyone that two suspicious elements had sneaked into the military academy and were conducting a search. It turned out that two Japanese spies sneaked into the military academy by car, spying on information and plotting to assassinate Chiang Kai-shek or other military and political personnel; After being discovered, he immediately fled by car. No murderer was found afterwards, which is an unsolved case for the time being. Soon, the "August 13th" Sino-Japanese War broke out. Shanghai and Nanjing are close at hand. Chiang Kai-shek prepared several times to go to Shanghai to inspect and direct operations. However, due to the tight blockade of the railway and highway between Nanjing and Shanghai by Japanese planes, it has not been possible. On August 25th, at the Supreme Military Conference convened by Chiang Kai-shek, Bai Chongxi, deputy chief of staff, suggested to Chiang Kai-shek that Xu Gesen, the British ambassador to China, would go to Shanghai from Nanjing the next day to meet the Japanese ambassador to China, and he could take his car. At that time, Britain was still a neutral country and was not bombed by Japanese planes. Chiang Kai-shek agreed. Huang Xun also attended the meeting. After the meeting, Huang Xun immediately reported to Nanzao Yunzi.
The next day, Chiang Kai-shek was tied up urgently and temporarily terminated his trip to Shanghai. As a result, the British ambassador's car was repeatedly chased by two Japanese planes on the Shanghai-Nanjing Highway in Jiading District. The car was overturned, Ambassador Xu Gesen was injured in the back, shot in the liver and dying. The entourage hurriedly bandaged Ambassador Xu Gesen to stop bleeding, carried him into the car and sent him to Hong En Hospital in Huxi for emergency treatment.
After the incident, the world was in an uproar. This can be said to be the biggest failure since Nanzao Yunzi debuted.
