In China, talking about TiananmenSquaremassacre1989 is LESS extreme than saying Taiwan is a country.
The CCP has brainwashed enough citizens to believe that the government did the right thing in 1989, even if you show them the massacre footage. They think the students were terrorists who deserved to be crushed.
On the other hand, most people in China believe that saying Taiwan is a country would be the biggest crime you can imagine.
You really should try it. I found it faster than some native apps.
