I encourage anyone browsing through this to read that link. It gives insight on what many Westerners have no visibility into - how many Chinese view the Qing dynasty, which was romanticized by Spielberg's Last Emperor. More importantly, it's a clue on why China is fervently cracking down on this.
If you search on Google, there's a slew of Chinese restaurants in the US named "Ming Dynasty." If you were in the SF Peninsula in the 80's and 90's, the one on Embarcadero and 101 drew well known chefs from Hong Kong during its heyday. Conversely, Google knows of two "Ching" or "Qin Dynasty" restaurants in the US. Many Han Chinese have always looked down on the Ching Dynasty as illegitimate colonialists.
This particular issue is a sore point with the CCP with respect to Hong Kong. During the crackdowns in 2019, mainland propaganda justified the crackdown as de-colonization. They called the British takeover an invasion to force subjugation through mass drugging (opium).
In response to this, many protestors appealed to Han-centrism. They argued that the Ching were already an illegitimate colonizing force, and blame them for everything that led up to Western colonization. This includes everything from weakened military might to failed trade/war negotiations, to anti-opium crackdowns. If the British broke in, it's because the Manchus left the door open. And by legitimizing the Ching Dynasty, you have an indirect trail of responsibility to the CCP themselves.
This Hong Kong link is why this Tang issue is not a joke to the CCP.
Final note because I have to pre-emptively address this on social media: If you feel like you need to jump in with a generic anti-colonial comment, don't. Hongkongers' views of being British subjects, especially from 1970's on, should absolutely not be seen through Western, especially modern progressive PoV. TL;DR - the majority, often vast majority, of Hongkongers wished to remain under British rule.
