traveling around southern China I would like to fly from WUH, CTU, CAN, or CKG or that area to LAX. I would like to find a flight that has a stopover in HKG before LAX. Is there anyway other spending a long time with a travel agent to find out if this kind of routing exists?

basically I would like to stopover in HKG before returning to the states and I know once you leave mainland your one entry visa is up.

I know I'm reaching for the stars, but hey somebody might be really knowledgeable.

thx
