Zhu Youzhen
It is not known when Lady Zhang was born. She was from a rich household in Dangshan (碭山, in modern Suzhou, Anhui), where Zhu Quanzhong was from as well. Despite her family's wealth, she married Zhu Quanzhong (who was then still named Zhu Wen) before he became prominent. She was the mother of his fourth son Zhu Youzhen.
