Chang Ya-juo
章亞若
Born	Chang Mao-li (章懋李) 1913 (1913) Jiujiang, Republic of China
Died	1942 (aged 28–29) Guilin, Guangxi, Republic of China
Known for	Being the mother of Chiang Ching-kuo's illegitimate twin sons
Partner	Chiang Ching-kuo
Children	John Chiang (蔣孝嚴) Winston Chiang (蔣孝慈)

The twins took their mother's surname. Chang Ya-juo died under mysterious circumstances; after dining at a friend's house, she came home complaining of stomach cramps. She was admitted to the hospital in Guilin and died the next day.

After their mother's death, the twins were raised by Chang's brother and sister-in-law, Chang Hau-juo (章浩若; Zhāng Hàoruò) and Chi Chen (季琛; Jì Chēn), respectively, who were officially listed as their parents. They escaped to Taiwan with their uncle and aunt in 1949 and settled near Hsinchu.

After a legal process that included obtaining written declarations from Chi's sons, documents attesting to the father-sons relationship between Chiang Ching-kuo and the twins from retired general Wang Sheng (王昇; Wáng Shēng), the birth certificate listing Chang Ya-juo as his mother and DNA testing to prove that Chi was not his birth mother, John Chiang was able to obtain a new ID card listing Chiang Ching-kuo and Chang Ya-juo as his biological parents in December 2002. John Chiang officially changed his surname to Chiang in March 2005.

In 2006, Chiang stated he knew the identity of his mother's murderer, to be revealed as one of Chiang Ching-kuo's aides in his forthcoming memoirs, but that Chiang Ching-kuo had not ordered the murder and was not aware it was to take place.
