Question about 24hr direct transit.

Hello, could you give me an answer? I am not sure I might be okay to pick up my luggage in PEK.

I booked 2 round tickets.
Ticket 1. Incheon- (Qingdao 1hr transit) - PEK Terminal 3
Ticket 2. PEK Terminal2 - (Russia transit) - Croatia

So it is clear that I will take a flight from PEK within 24hours after I landed to Qingdao.
However, I would like to know if I can get my luggage from terminal 3 and go to terminal 2 without visa.
Also, since my ticket is separated round ticket, I am not sure it can be considered as a transit.

Thank you in advance!
