Get visa in Beijing

Hi. I am traveling to China almost every year once or twice. Now going to Canton Fair (I have my photo ID badge for Canton Fair). I bought my flight tickets, to BJ and BJ-GZ-BJ. But just realised, my double entry one is expired in September. My flight is on this Monday, the Chinese embassy is closed today (Friday) in Hungary. Could I get a VOA on the Beijing airport for sure?
I'm a Hungarian citizen.
