Can I re-enter Hongkong after visiting 2 days in MACAU (Indian tourist)?

Hi,

I have Hongkong PAR. I will be in Hongkong for 4 days and then will visit MACAU for 2 days. Can I re-enter Hongkong again as I have flight from there. I guess no external PAR or visa is required but still please let me know.

Thanks,
Neha
