Do I need re-check in to my luggage in Beijing airport?

I am traveling to Korea (Busan) from Cairo, Egypt, through a transit in Beijing airport.
My question is, should passenger in Beijing airport take his luggage and make re-check in form them? Or they will be transfer directly to other plane?
I am asking because I had a transit before in Guanzou airport and I re-checked my luggage there. It was very inconvenient for me.
Thanks in advance
