To say that the first Chinese secret agent is undoubtedly Dai Kasa, Who is extremely excellent in both intelligence detection and training of spies, so he is deeply valued by Chiang Kai-shek, and let Dai Kasa single-handedly establish the Military Intelligence Bureau. Although Dai Kasa provided a lot of useful information in the War of Resistance Against Japan, because of the discord between the Kuomintang and the Communist Party, many patriots who were members of the Communist Party could not escape death after being caught by Dai Kasa.
Before Chiang Kai-shek decided to go to Taiwan, he had asked Dai Kasa to assassinate someone, but after Dai Kasa knew who was going to be assassinated, Dai Kasa risked being demoted and rejected Chiang Kai-shek. The person chiang kai-shek ordered to assassinate was Ms. Soong Ching Ling, the widow of Dr. Sun Yat-sen, and although Dr. Sun Yat-sen had died, Ms. Soong Ching Ling was still called the Mother of the Nation, and even if the Communist Party and the Kuomintang were at odds, Dai Kasa would never dare to risk being crusaded by the people of the whole country to kill Soong Ching Ling.
Although Soong Ching-ling had already drawn a clear line with the Song family, Song Ziwen had warned Dai Kasa in his early years that he absolutely could not touch any one of the Soong family, not to mention what kind of trouble Dai Kasa would cause if he assassinated Soong Ching-ling, but if Soong Ching-ling was really assassinated by Dai Kasa, it would inevitably intensify the war between the Kuomintang and the Communist Party, and let China, which had been difficult to restore peace, once again fall into war.
Moreover, Soong Ching Ling and Soong Mei Ling are sisters, although the two are now in different political positions, but how can the family affection be divided by saying that division can be divided, and Chiang Kai-shek loves and respects Soong Mei Ling very much, if he really listens to Chiang Kai-shek's orders and kills Soong Ching Ling, the first person who will not let go of himself is Soong Mei Ling, even if Chiang Kai-shek will support Dai Kasa, but if Chiang Kai-shek is moved by Soong Mei Ling, then Dai Kasa will have no foothold in China, so Dai Kasa will definitely not accept this task of Chiang Kai-shek.
Dai Kasa did not lose money to do intelligence work, and was able to understand these problems at the first time and reject Chiang Kai-shek, if Dai Kasa really assassinated Soong Ching Ling, then Dai Kasa would become a sinner in all of China.
