New History of the Five Dynasties
In 911, Emperor Taizu spent the summer at Zhang's summer mansion. He used the opportunity to have sexual relations with virtually every woman in Zhang's household. Zhang's son Zhang Jizuo (), humiliated, wanted to assassinate the emperor. Zhang Zongshi pointed out that it was because of Emperor Taizu's initially stopping Li Hanzhi's attack that the Zhang household was preserved, and he managed to persuade Zhang Jizuo not to carry out the assassination. (According to Zhang's biography in the "New History of the Five Dynasties", the women that Emperor Taizu had sexual relations with included even Zhang Zongshi's wife Lady Chu and his daughters.)
