Chiang Ching-Kuo bowed down to Hirohito in Japan: In the late 1960s, when Defense Minister Chiang Ching-kuo visited Japan, Hirohito told Chiang that he would never forget President Chiang’s kindness in repaying evil. Chiang’s mother had been killed by a Japanese bombing, and he had vowed revenge, writing “Blood for blood.” However, he ultimately bowed down to Hirohito in Japan. 60年代末，“国防部长”蒋经国访问日本，裕仁向蒋经国表示：蒋总统以德报怨，他永远都不会忘记. 蒋经国生母就是被日本人炸死的，他曾发誓报仇，手书“以血洗血”。结果去了日本跟裕仁点头哈腰.
