If by remembering their heritage you mean how half the US remembers they're 1/16 Irish only when St. Patrick's day rolls around, then yes. HK is in a catch-22.

If by remembering their heritage you mean how half the US remembers they're 1/16 Irish only when St. Patrick's day rolls around, then yes. HK is in a catch-22. Stay where they are and get absorbed into the Mandarin speaking behemoth that's mainland China like Hakka, Wu, and Hokkien speakers once the CCP starts tearing down border and population movement restrictions, or move abroad to a dozen different countries and be absorbed piecemeal into the Anglosphere. The third option would be for 1 million or so HKers to build a new city somewhere where they could be the dominant culture. Unfortunately, Singapore is a very unusual case in world history where Malaysia didn't care about sovereignty over the land Singapore stood on and actually forced them out. Very little chance of that happening a second time.
