In the Qing dynasty, there were two types of Manchu“separate-register households”:the detached separate-register households（linghu lingji dang’an）and“self-declared”separateregister households（zishou lingji dang’an）. During the Qianlong reign, the self-declared-separateregister households were not included in the Eight Banners system, while the detached separate-register households were kept in the system because they had received military awards. The Qing government undertook several effective measures in the auditing of separate-register households that helped to optimize the Eight Banners system, temporarily relieved the problem of banner livelihoods, and eased the financial pressures on the central government. The self-declared separate-register households received more opportunities to earn a living, but the changes intensified the division between bannermen and the Han people. In the long run, the auditing of the household registers could not fundamentally solve the various problems of Eight Banners livelihoods.
