do you mean HKG-PEK-NRT-PEK-HKG?

the T&C says that The member or the Nominee may make two stopovers, two transfers or one open-jaw at either the origin, en route or turnaround point on all airline partners except Air China and Iberia where no stopovers or open-jaws are permitted.

assuming you are doing HKG-PEK-NRT-PEK-HKG, you will need to have PEK, NRT and PEK as either a stopover or a transfer. since you are only allowed two transfers and no stopovers, your itinerary cannot be booked within the rules.

hope this is what you're looking for.
