医疗保险公司不负责买，政府没有这方面的强制规定。不过你自己倒是可以买一些商业保险，到时候你可以咨询一下其他外国同事。另外，回国机票的话，等你合同期满了，公司可以给你报销。

Our company isn't responsible for medical insurance. The government doesn't make this mandatory. However, you can purchase private insurance yourself. When you need to, you can ask the other foreign employees for advice. As for a return ticket, after your contract is up you can write it off and we'll provide a refund.
