In 1975, Chiang Kai-shek died of illness in Taiwan Province, when everyone thought that Zhang Xueliang was going to restore his freedom, but Chiang Ching-kuo continued to put Zhang Xueliang under house arrest, until after his death, Zhang Xueliang regained his freedom, at this time he had been imprisoned for fifty-four years, in fact, the reason why Chiang Ching-kuo was reluctant to release Zhang Xueliang was precisely because of his father's thousands of instructions before his death, and the old Chiang was still angry with Zhang Xueliang before his death.
Originally, Chiang Kai-shek and Zhang Xueliang had the same brotherhood, but because of the Xi'an Incident Chiang Kai-shek hated Zhang Xueliang to the bone, if it were not for the threat of the Northeast Army and the intercession of Song Meiling and others, Zhang Xueliang might not have been able to save his life, but during the period of house arrest Chiang Kai-shek did not treat him harshly, but he was treated very well, so Zhang Xueliang's one-year house arrest actually cost a lot, and this money did not dare to calculate at all for more than half a century.
Chiang Kai-shek would rather spend a huge amount of money to restrict Zhang Xueliang's personal freedom, in fact, he did not trust him, because Chiang Kai-shek still believed that the reason for his failure was the betrayal of Zhang Yang and the two people, and he did not know that the real reason for losing Jiangshan was to deviate from the people's hearts, so he could not let go of this knot in his life, even if he met Zhang Xueliang many times later, but Chiang Kai-shek never said a word to the other party.
Old Jiang specifically told his son before he died that he absolutely could not let the tiger return to the mountain, he believed that Zhang Xueliang always had different intentions, if he went out and united with the old subordinates again, then it would be unfavorable to them, so he resolutely did not let Jiang Jingguo release Zhang Xueliang, and Chiang Chingguo obeyed his father's teachings, so the father and son were under house arrest for fifty-four years, fortunately Zhang Xueliang was a rare longevity, otherwise I am afraid he would not be able to wait for the day to restore his freedom.
