Macau residents in Zhuhai can rely on other companies to buy social security?

Yes. The law does not explicitly provide for "dependence" on the payment of social security illegal, although the dependence on the company to pay the social security itself is not illegal, and in fact, there are quite a number of enterprises in the payment of social security on behalf of non-employees, but both for the enterprise and the individual, dependence on the company to pay the social security or the existence of a greater risk of legal action. Social security refers to social insurance. Social insurance refers to a social and economic system that provides income or compensation for the population that is incapacitated, temporarily out of work, or has suffered a loss due to health reasons.
