Hello,
I have a Z (work) visa that became valid on October 5, 2009 (when I entered China after a vacation in South Korea). I want to book a holiday in Yunnan province for the last few days of this visa, but have recently been informed that I was bumped from the October 3 flight I had booked, and the next available is October 6. I'm only very half-heartedly considering this, but what is the penalty for overstaying a work visa for one day?

Thank you,
Angela
