Du Yuming
Yang married Chih-li Tu (), a teacher, in 1950 and has two sons and a daughter with her: Franklin Jr., Gilbert and Eulee. His father-in-law was a Kuomintang General Du Yuming. Some scholars suspect that Du was promoted to a high-ranking position in Chinese People's Political Consultative Conference in order to convince Yang to return to China after seeking refuge in the US. Tu died in October 2003, but in December 2004 the then 82-year-old Yang made controversy by marrying the then 28-year-old Weng Fan ().
