Do I need to go abroad to stay in regal hong kong hotel?

When you transfer in Hong Kong and check in at Regal Hotel in Hong Kong Airport, you have to enter the airport (not leave the airport), that is, after you get off the plane, you have to go through the immigration card, go through the immigration formalities and stamp it, then pick up your checked baggage before you leave, then enter the airport lobby and then start again, and then turn left along the passage to reach Regal Hotel in the airport, so if you don't enter the airport (not leave the country, you will go to other places in Hong Kong), no.
