Can i stay go into the main terminal area of Beijing Captial Airport without a Chinese visa?

I will be arriving into Beijing Airport Terminal 3 and will have over 5 hours wait for my transit flight departing from the same terminal. Would I be able to go into the main terminal area without a Chinese visa, rather than staying inside the restricted transit area? How do I do this, please? For example, would I have to go through the immigration, and then go back in through the immigration again? Thank you in advance for any advice.
