I definitely think the technology surveillance in China has intervened...most of the people in the world. What do I mean by that?
My laptop, my cellphone, have been constantly monitored, I believe, by the Chinese government. I was invited to a Uighur wedding a few years ago. Because our conversation was monitored, the Chinese police knew that I was going to attend this wedding through our conversation on our cellphones. The newlywed couple were threatened that they should not invite people like me to their wedding.
Also, my and my family's conversations have long been monitored, including through my laptop. The camera would turn on multiple times. The mouse would move by itself frequently. Also, whenever I check the IP address of who has visited my email, I can that see it is from a Chinese IP. I believe this is happening not only to me; it's happening to many other people who are living in the United States and Canada.
