Is it reasonable for a partnership to pay social security in the company without paying wages?

Of course, business partners can pay social security normally without wages. As long as you are not insured in other work units, you can be insured in your partner unit. No matter which company participates in social security, a person can only participate in one of them. Because when you retire in the future, you can only get a pension, including a medical insurance reimbursement, so it is meaningless to say that if you take out two or more social insurances at the same time, it is equivalent to a situation of repeated insurance, and eventually you will have to return it.
