Can social security for flexible employees in Xuzhou be done in any street?

No, both are fine. According to the announcement issued by Xuzhou Social Security Bureau, the social security of flexible employees in this city can be handled in the street office where their household registration is located, not in any street office. Flexible employment refers to various forms of employment based on industrialization and modern factory system, which are different from traditional mainstream employment methods in working hours, income and remuneration, workplace, insurance and welfare, labor relations and so on.
