I don't know about that.
When I was in Beijing, I saw that the visa application centre was upstairs, and downstairs there were all types of advertisements. That's not against the law, but sometimes it can get murky as to who is referring to whom. I want to be clear that they shouldn't be doing it, and if it requires opening a contract or adding a few words to a contract, I think we should do it now. If not, there's a loophole, and it could be easily exploited for many years.
