Yes there are PVG/PEK HKG flight where DL take you to China and you transfer to MU or CZ. But I would stay away from connecting TPAC to MU/CZ operated China to HK flights. Timing is bad for DL arrival, flights to HK or within China are more prone to delays, they are a PITA to get onto your 006 ticket stock if it can even be done at all, catering will definitely not be suitable for non-Chinese palate and you are dealing with a majority of the passengers from a different culture.
Been there and done that: no mas, 不要!
