At the local levels, this involves monitoring workplaces and residences to identify Falun Gong practitioners, making daily visits to the homes of known (or "registered") Falun Gong practitioners, or coordinating and overseeing 24-hour monitoring of practitioners.[1][7] The 610 Office does not necessarily conduct the surveillance directly; instead, it orders local authorities to do so, and has them report at regular intervals to the 610 Office.[4] Basic-level 610 Offices relay the intelligence they have collected up the operational chain to the 610 Office above them.[3] In many instances, the surveillance is targeted towards Falun Gong practitioners who had previously recanted the practice while in prison or labor camps, and is intended to prevent "recidivism."[7]
