China passport, Australian PR, can freely enter and leave any city on the mainland that flies directly to Hong Kong. Do you need an endorsement? Please answer if you know, thank you!

If you go abroad through Hong Kong (instead of going back to China immediately after going to Hong Kong), you have a joint ticket and the visa of the other party (such as a ticket to Australia and PR in Australia), and you don't need to sign an endorsement if you stay in Hong Kong for more than 7 days.
