What is a temporary residence permit? Where can I deal with it?

This is a unique floating population management system in China. China's cities implement the system of temporary residence registration and temporary residence permit. "Temporary residence permit" is the legal proof of temporary residence of foreigners in this city; After the migrants arrive in this city, they shall declare their temporary registration to the local police station within three days. Among them, migrants who have reached the age of 16, intend to live in this city for more than 1 month, or intend to engage in work, business and other activities in this city, should apply for a "temporary residence permit" while handling temporary residence registration. This is a management system that lacks humanization. At the same time, it also highlights the bureaucratic style of law enforcement agencies and household registration management agencies in China. It also shows that our socialized management is backward and unscientific.
