蔣緯國
While the young Chiang Ching-kuo had a good relationship with his mother and grandmother (who were deeply rooted to their Buddhist faith), his relationship with his father was strict, utilitarian and often rocky. Chiang Kai-shek appeared to his son as an authoritarian figure, sometimes indifferent to his problems. Even in personal letters between the two, Chiang Kai-shek would sternly order his son to improve his Chinese calligraphy. From 1916 until 1919 Chiang Ching-kuo attended the "Grammar School" in Wushan in Hsikou. Then, in 1920, his father hired tutors to teach him the Four Books, the central texts of Confucianism. On 4 June 1921, Ching-kuo's grandmother died. What might have been an immense emotional loss was compensated for when Chiang Kai-shek moved the family to Shanghai. Chiang Ching-kuo's stepmother, historically known as the Chiang family's "Shanghai Mother", went with them. During this period Chiang Kai-shek concluded that Chiang Ching-kuo was a son to be taught, while Chiang Wei-kuo was a son to be loved.
