Macao - Hong Kong arriving questions

Hi, I have basically 2 questions:
1) if I'm travelling Macao-Shanghai-South Korea then will I be qualified for 144 hours visa-free transit? I have a passport that gives me that opportunity, but not sure if Macao status and if it has the same exceptional rights as Hong Kong.
2) If I would use Hong Kong - Shanghai bullet train as transport from country A to China, will I be declined with 144 hours visa-free transit?
