Hi,
I am currently living and working in China. My contract expires in April and after that I'll get a tourist visa for another 30 days, but with 0 entries as I am applying for it in China. I am planning to travel to Vietnam, but am intending to come back to China again, which means I would have to apply for another tourist visa for China. My question is if that is possible or not. A problem might be that I do not have a return ticket to europe yet, so, is that a risk that a Visa could be denied?

I would be very grateful for any help
