I am going to Raleigh, North Carolina and transferring at Newark Airport. Could you please tell me how to transfer?

If your luggage is checked directly to Raleigh, you should be able to apply for both boarding passes before leaving China. After arriving at Newark Airport, you can directly find the airport where you want to take the flight. At the boarding gate, just give the staff your pre-registered boarding pass. If not, just leave me a message and I'll tell you.
