1949, the Kuomintang defeated Taiwan Province Province, and Xiao Yan and Xiao Ci were escorted. They went to Xiamen with grandma and others to Hsinchu, Taiwan Province Province, and settled in Hsinchu from then on. Young small swallow and Zhang Xiaoci almost traveled all over China, but they never thought that they would be separated from Chinese mainland for more than 50 years. Small swallow's brothers have been troubled by their life experiences since they were very young. In high school, because of the discussion of people around them, they gradually know that they have a special life experience, but they can't prove it. When asked about grandma, she always kept her mouth shut, fearing that telling the truth would cause great emotional harm to her young grandson or cause other unexpected troubles. It was not until they entered the university that an insider discovered the mystery of their life experience. When they were told that their biological father was Jiang Jingguo, they had a strong desire to recognize their ancestors. But to their great distress, due to political reasons, Jiang Jingguo didn't openly admit this father-son relationship before his death, so they had to hide their life history all the time and became very sensitive and particularly taboo to the outside world. After entering the diplomatic circle, small swallow became more cautious. For example,19701February 12, when he married his wife, Huang Meilun, in Belgium, she kept a low profile to avoid attracting outside attention. After Jiang Jingguo's death, the news media in Taiwan Province Province began to reveal the inside story of their lives. Lee Teng-hui also publicly acknowledged that small swallow and Zhang Xiaoci were descendants of the Chiang family, but other descendants of the Chiang family disagreed, especially Jiang Jingguo's wife Jiang Fangliang, who was still alive and knew nothing about it. Making this relationship public at this time is bound to hurt his feelings. Jiang Jingguo's third son, Jiang Xiaowu, had a good relationship with small swallow, but he was alienated from small swallow because of his different political views. All this indicates that the Zhang brothers will have a long and arduous road to recognize their ancestors and return to their ancestral home.
