I am a non-Zhongshan resident and work in Zhongshan. What is the minimum standard for buying social security in Zhongshan? The minimum kind includes the outpatient insurance in the medical insurance?

It's not the same everywhere. The medical insurance does not actually reimburse for outpatient care.

There are two main considerations when choosing a social security system, one is the medical aspect, this is of course where to live where to do well, because it will involve the medical expenses reimbursement discount, whether it is convenient and so on. On the other hand, the pension aspect, if you say that you are now in Zhongshan for, the payment is according to the level of Zhongshan, if you return home later, the money received is according to the local average social wage level in your hometown to receive.

The main thing is to weigh these two aspects. Because I don't know the social security situation in Zhongshan, so you can go and find out before you decide.
