This matter has been spread everywhere, it's typical bragging, with a lot of exaggeration.
It seems that they were called to the police station for questioning because of some illegal activities they did, and then they came out and started talking nonsense.
Before the law is enacted in China, everyone is pretty safe, but I estimate that the law will be enacted in about a year. After it's enacted, I don't know if it will be retroactive.
I can roughly guess how the law will be written, but I won't say it, to avoid being accused of creating panic.
In short, there is still about a year to play around.😇
