You should keep in mind that when you see mainlanders being interviewed on public TV, you should be aware of what they can say. Of course, some of them actually do believe in wolf-warrior diplomacy, but I also believe that when anyone is speaking on TV, any forced confession will tell you that you have to be very cautious about what you say.
What I do think is an indication, despite the fact that this was my point, is that you are seeing ordinary mainlanders such as taxi drivers—not activists—posting on social media in support of Hong Kong people and getting picked up. I think that's an indication of how powerful it is—how, despite all the censorship, you can't shut down the information flow, even with the law, even with all the apparatus of law and security and the technology apparatus. We didn't even talk about the technology aspects of all this, and perhaps that would be a good follow-up hearing.
So that's extremely important. We have actually looked at and tried to compile cases of mainlanders who support this. I think it's quite shocking and encouraging that one person.... Mainland law requires real-name registration. This means that when you post online or do anything online in the mainland, you have to register with your real name, which means they can track you down and they know your IP address, so that one person who posted a one-star review of the Hong Kong national security law was really courageous to do that.
You can say anything you want in China, as long as it's consistent with the party narrative. The minute you even question or characterize it, you could run afoul of it with charges of incitement, sedition, disloyalty, being anti-China, etc.
I'm not sure if I answered the question.
