If you actually follow what is actually practiced, Hong Kong citizen have essentially lost their Democratic rights since. The Hong Kong citizens no longer can elect officials that have real power(lost of the second system, for all intent and purposes). Yes, on paper, it’s still two systems, in reality, it’s not. Similar to the Texas abortion non-ban. On paper, it’s not a ban, in practice, it’s more or less a ban. To argue otherwise is to deny reality. Here’s a sample of that type of analysis.

If you have other credible sources that shows otherwise, you’re welcome to share. I concede that there’s a high probability that I may have missed another angle to it and welcome challenges to that.
