Will the 5 minutes make difference and what happens if I overdue my stay?

How much is the visa on arrival? And how will they act on that i am standby passenger? I have Finnish passport. And how is the action on airasia on the subject.Flying through chonqing airport and arriving there 10.20am with Airasia flight and leaving next day 10.25am with Finnair. All the information is helpful, thank you.
