In the middle and late Ming Dynasty, the children of military households, under the shackles of the "military household hereditary system" and the crisis of "frequent border troubles", grew from ordinary soldiers who were forced to inherit military membership to generals guarding the Jiliao defense line. In the struggle for life and death on the battlefield, they understood that "serving as a soldier is not only the destiny of the family, but also the responsibility to resist foreign aggression and protect the country." They completed their growth and transformation from "prisoners of the system" to "pillars at the border".
