This isn't about values but control; everyone is supposed to have the same views and do the same thing quietly, so that the empire can function the way a few people want it to go on.

What the mainland China has taken advantage of with regards to HK is that many cheap mainland businesses/products have been related to the little nation that has learned from Brits; mainland companies/products are "upscaled" with wording "Hong Kong" or customers are told the owner is from HK.

Taking people of streets for speaking out or selling books that constructively criticize the mainland China affairs is a lame way to run any society. Hard to image teachers would disappear without a trace for hypothesizing how thing may be done differently or for suggesting some in power make mistakes and we are affected.
