Why is Beijing Social Security an employee of other towns?

Not residents with registered permanent residence in Beijing. Beijing's social security system includes the category of "non-local urban workers", which usually refers to those urban workers whose household registration is not in Beijing. This concept is relative to local residents. Therefore, if a person's hukou is not in Beijing, then his hukou is called "foreign town hukou" or "foreign town hukou". When handling certain businesses, such as Beijing, it belongs to the category of "employees from other cities and towns". Relative to local residents, residents refer to residents whose domicile is in this city. There is no difference between non-local urban hukou and non-local urban hukou.
