Xu Zhimo
She married the prominent poet Xu Zhimo (Hsu Chih-mo), and gave birth to two sons, Hsu Chi-kai (born 1918) and Peter Hsu (1922 – 1925). After giving birth to Peter, Youyi received a letter from her estranged husband, declaring his intentions to divorce. In his letter, Xu reasoned that "marriage not based on love was intolerable." Zhang consented, and signed the divorce papers. Their separation was the first legal divorce based on the Civil Law in China.
