On an individual level, it would appear that just being from Hong Kong and not China will get you death threats.
I feel compelled to clarify this: Hong Kong is part of China, and has been since 1997.

With China now in a state of ongoing non-compliance with its international obligations under the UN-registered Sino-British Joint Declaration, the UK will continue to work with international partners to hold China to its legally binding obligations on Hong Kong. Upholding the promises it entered into freely is in the best interests of Hong Kong’s stability and prosperity.
