Dai Kasa was a man who had also made meritorious contributions to intelligence assassination work, and during the War of Resistance Against Japan, he was cruel to the Japanese, but he also killed many communists and democrats. He studied at the Whampoa Military Academy, specializing in espionage, and after his graduation, he also gave full play to his professional knowledge and founded the frightening institution, the Military Command Bureau.

The Whampoa Military Academy is the training base for talents, which has sent a large number of talents to the Chinese revolution, and Dai Kasa is no exception, and he is also very proficient in assassination. Moreover, a large number of secret agents have been carefully trained and organized, all over the world, and there are also undercover agents in Japanese spy agencies, and even around the Japanese emperor are Dai Kasa's eyeliner, which shows how strong Dai Kasa's strength is, and is called "the most mysterious Oriental" by Westerners, which means that Dai Kasa's whereabouts are erratic and pervasive.
There are also strict auditing standards for the selection of secret agents, even if they can't reach the level of Dai Kasa, it can't be too different. As a major general of Chiang Kai-shek's confidant, Dai Kasa obeyed Chiang Kai-shek's orders most of the time, and when he received Chiang Kai-shek's task, he would certainly accomplish it brilliantly. For example, when Chiang Kai-shek ordered him to kill Wang Yaqiao, he did not hesitate for half a minute. It should be known that at that time, Dai Kasa had a very good relationship with Wang Yaqiao, and after receiving the order, he directly mutilated Wang Yaqiao, who was still a good friend yesterday, without the slightest hesitation.
But there are always exceptions, and there are also people who dare not move, Chiang Kai-shek has issued orders to him many times, and finally even threatened Dai Kasa with demotion and dismissal, and Dai Kasa still replied the same and did not agree. This person who did not agree to the assassination was Soong Ching-ling, and there may be many questions, why did Chiang Kai-shek and Soong Ching-ling, who were related to him, make such an order?
Chiang Kai-shek's wife, Soong Mei-ling, was Soong Ching-ling's sister, and it was reasonable to say that Chiang Kai-shek had to call Soong Ching-ling a "sister", but he would directly want to kill her. In fact, Soong Ching-ling has always been indifferent to Chiang Kai-shek, the relationship is extremely bad, and even family gatherings avoid Chiang Kai-shek, in Soong Ching-ling's view, Chiang Kai-shek's style of conduct has betrayed his husband, Mr. Sun Yat-sen, the original intention of founding the Kuomintang.
Soong Ching Ling can be said to hate Chiang Kai-shek very much, and even once directly accused Chiang Kai-shek of his actions in public. The contradiction between Soong Ching Ling and Chiang Kai-shek is already irreconcilable. This time, Chiang Kai-shek could not come to Taiwan, and privately he was moved to kill Soong Ching-ling. Later, in the "April 12" coup launched by Chiang Kai-shek, Soong Ching Ling directly and openly sided with Chiang Kai-shek and participated in and rescued Communists, including Liao Chengzhi and others. Chiang Kai-shek was very dissatisfied with him and ordered the assassination, but Dai Kasa did not agree.
