And as historians of schooling have long noticed, but few have taken up the charge, a full history of urban education would be more than a history of schooling.
I do believed that education can change a person's life, and more social factors will be discovered if we want to study in detail how people receive education. A person's life experience is more like a microcosm of a small society, in which social mobility can be every turning point in life, such as reading, getting married and having children, and so on.
