I suspect that if you called up and said that you wanted to change your ticket to PEK because you had a separate onward ticket to WUH, you'd probably get an agent to allow you a free change. A free refund -- probably not without a waiver. But, changing the ticket to go somewhere else, and paying the fare difference? You might need to HUCA once or twice, but I suspect you could find someone to make an exception.
