I'm a bit confused about TWOV flying to Japan with a “technical” stop in DLC.

I want to fly MEL-PEK-KIX / HIJ-(DLC)-PEK-MEL or visa versa. I know I can get a TWOV in Beijing on the way to/from KIX because it’s nonstop but will there be issues flying to/from HIJ even as a transit passenger (less than 24hrs) because the flight between DLC-PEK is apparently considered domestic? I know a Beijing 72hr TWOV isn’t really allowed flying HIJ-(DLC)-PEK-MEL because Liaoning Province sets my zone. But is it possible MEL-PEK-(DLC)-HIJ because my transit in DLC will be less than 24 hours?

I only want a TWOV in Beijing in one direction but would prefer it on the way to HIJ instead of KIX
