I have had an experience at HKG, where my first flight was delayed - on a ticket with a 1hr scheduled transit. I was flying ADL- HKG - PVG.
upon landing at HKG, ground crew gathered everyone making the transit to the next flight and (literally) ran with us through the airport to the flight. At the security screening, an empty line was opened up just for us and we ran through and boarded our next flight.
Assuming your flights are on the same ticket, in my experience, CX will look after you at HKG.
However, our bags did not make it onto that flight and arrived on a separate CX flight two hours later (CX or KA flies almost hourly into PVG).
