After the German reformer Martin Luther married former nun Bora, they gave birth to 6 children, 4 of whom grew up. Based on his own theological theory and fatherhood, Luther cared for his children and gave them a good family education. Like many ordinary parents, he actively arranged a way out for them. However, he also encountered conflicts with his eldest son Johannes in career planning: Luther had high hopes for Johannes, hoping that he could inherit his career, but Johannes chose jurisprudence that Luther did not like. Despite Luther's careful training and the care of his friends, Luther's three sons and one daughter had different development paths. The fate of Luther's children was a microcosm of the times.
