You’d still have to explain what kind of traditions you mean.
Well, there is the cantonese ethnic group with their own traditions like food, they have a different history than people from northern china, the people may be more spiritual than mainland china, the cantonese language itself is distinctive from other chinese language (it is a dialect of the yue languages), hong kong itself has its own history and culture because it’s been an ‘east meets west’ city for so long
I don’t think these aspects are specific to HK, I would imagine it would be like someone from a minority ethnic group in South Africa or India or Afghanistan where they want to preserve their own ethnic group’s language and culture and history against the majority group’s culture
