Visa hours of China Embassy in Moscow?

I am a Canadian, teaching in Moscow, and myself and a Scottish friend are doing the Trans-Mongolian in the summer. Because we are teachers, our hours to hand everything in is a bit limited. From what I can see, the visa office is only open 9-12 monday - friday??? Is there any way around this? We would like our passports back ASAP as well, as we have other travel plans and needs for them in Russia.
