Does a sole proprietorship enterprise have anything to do with buying social security?

According to the provisions of the Social Insurance Law, social insurance premiums cannot be paid in the company without labor relations. Insured employees must establish labor relations with the employer before they can pay social insurance through the employer. No unit or individual may obtain the qualification of social insurance participation and payment through fictitious labor relations or forged certification materials. Units and individuals that violate these provisions shall bear corresponding legal responsibilities.
