Chinese nationalism is based off of empirial expanionism, which deviates from the original sense of nationalism which embraces democracy, egalitarianism, and universalism. Hong Kong nationalism should reject the notion to merge with Chinese nationalism which rejects these universal ideals and instead build the unique identity based on the historical divergence since British occupation. (Even back before then, settlers lived in HK were vagabonds who rejected the old dynasties so stopped trying to justify the historical claims of HK belonging to China)
