but on this itinerary you still have to transfer from SZX to HKG- even if you take a cab to shekou and catch the fast ferry direct to HKG you have wasted at least 4 hours in transit - more if you don't have a good connection
so it may pay to bite the bullet and just find a local SHA agent to sell you a cheap one-way to HKG (yes a local agent not online booking with expedia or travelocity - and offer to pay cash!)
or, try air macau - which can fly you both from the mainland and to taiwan, with an easy connection at MFM, without changing airports
if you've never been to macau its worth a day or two on your way to TPE- and the local agents there offer deep discounts, too
