Although Soong Mei-ling and Chiang Kai-shek have been in the same boat for fifty years and have a deep affection, unfortunately the two do not have children of their own, and Chiang Kai-shek's only one biological son is Chiang Ching-kuo, which is the person who was born to him and his original partner, Mao Fumei, and in Chiang Ching-kuo's heart, he has always destroyed Soong Mei-ling's family, so there has always been a gap between him and Soong Mei-ling.
Chiang Kai-shek has been working hard between the two of them, hoping to ease the relationship between the two, he often said good things about Chiang Ching-kuo in front of Soong Mei-ling, and then told Chiang Ching-kuo about Soong Mei-ling's concern for him, and repeatedly warned Chiang Ching-kuo that he must treat Soong Mei-ling as his own mother, and if he dies one day, he hopes that Chiang Ching-kuo can take good care of Soong Mei-ling.
But for Chiang Ching-kuo, he always had a grudge, because he and his birth mother had a very good relationship, although under Chiang Kai-shek's efforts, the two appeared to coexist peacefully, but after Chiang Kai-shek's death, the two immediately returned to their previous indifference, and Chiang Ching-kuo publicly announced at Chiang Kai-shek's memorial service that he would bury his biological parents together, which made Soong Qingling extremely disappointed.
Losing Chiang Kai-shek's protection, Soong Mei-ling knew that he had no foothold here, so he went to the United States a month later, and since then he has lived alone in the United States, and When Chiang Ching-kuo was critically ill, Soong Mei-ling also visited him, and then Chiang Ching-kuo died, and When Soong Mei-ling knew about it, he said: Life is impermanent, and he leaves without greeting. Although the relationship between the two was not intimate before they died, they only felt sad at this time.
