Dai Kasa was the head of the military command during the Republic of China period, and the military command he led was pervasive at that time, which made the Japanese army invade China suffer a lot. Dai Kasa's concept of hometown is very heavy, so most of his employers tend to choose the same place. In 1932, Dai Kasa was responsible for the enrollment of the first phase of the Special Training Class of the Zhejiang Police Officers School, only 13 people were recruited at that time, but there were many people who signed up, one of them was named Jiang Yiying, she and Dai Kasa were from Jiangshan County, Dai Kasa saw that it was a fellow villager who was very happy, immediately called it to the office, and after inquiring, he found that this person had a quick mind, so he immediately decided to hire.
After graduating from the police academy, Jiang Yiying was assigned to the Translation and Telecommunications Section of the most classified department of the military command as an interpreter. Jiang Yiying worked seriously and had strong professional ability, and soon she was promoted to the post of chief operator of the Xiamen Radio Station of the Military Command, and after the outbreak of the Anti-Japanese War, Dai Kasa ordered her to be responsible for deciphering the secrets of japanese and fake radio stations. In order to please Bo Dai Kasa, she reported everything to Dai Kasa. It was during this time that she deciphered an important piece of information: the Japanese were about to attack Pearl Harbor in the United States. After she reported the information to Dai Kasa, Dai Kasa was very happy and immediately submitted the contents of the telegram to Chiang Kai-shek, who, with Chiang's consent, informed the U.S. Naval Command of the information. But the Americans at the time did not value China, believing that the intelligence of the Chinese was inaccurate, and even suspected that the move was to stir up relations between the United States and Japan. Soon, though, the Americans paid the price. In the early morning of December 7, 1941, Yamamoto commanded the Japanese Navy to attack Pearl Harbor and severely damage the U.S. Navy. Only then did the Americans wake up and repent of not having done it.
After the Japanese attack on Pearl Harbor, the Americans began to look at China's intelligence capabilities, and US President Roosevelt personally received Dai Kasa, after which the two countries established the "Sino-US Intelligence Cooperation Institute". Jiang Yiying cracked the Secret Telegram of the Japanese Army and made a great contribution, so she was promoted to the chief of the Translation and Telecommunications Section, and was soon promoted to major general, becoming the only female major general in the military command. The level is higher, and the temper is naturally greater. After that, she often quarreled with her husband over small things, and lost her temper slightly, and eventually her husband could not bear to divorce her.
After the divorce, Jiang Yiying fell in love with Li Shuzheng, who was then the chief of staff of the Xuzhou Bandit General Headquarters, and at this time Li was already a lieutenant general, which can be said to be young and promising. However, Li Shuzheng, a "heroine among women", did not move, but refused Jiang Yiying's show of love with "a virtuous wife". In 1949, Jiang Yiying retired to Taiwan with the defeat of the Kuomintang, and later married a businessman surnamed Ni. Jiang Yiying and her ex-husband do not have children, and the children are born to her second husband. Although she is the only female general in the military command, her descendants are very low-key, only one granddaughter is active in the performing arts industry, and the other children and grandchildren rarely appear in external activities.
