Actually there are so many reason people get here,but some word... I don't know how to say it.I'll try to describe my situation.If you don't understand ,never mind.
In Chinese,1990's.We did't pay attention to student's education.So some of them were encourged to using demonstration.By this way to ask leader do something.
However,this demonstration became destroy society,by hitting people,destorying buildings,and robbing things.

@mao Thanks マオさん、Yeah, I’m a fan of 三体小説 then I might know some of yr situation at there. #マストドンsf部🛸

@nashiki Well...
>三体
That's similar,but not same.I'm sorry my english can not explain it.
If you are interested in it,you can search someting about“日本赤軍”.They are related to China and even some history.I'm sorry that I don't know how to judge them.
Hope you can get what you want

@nashiki And our leader finally stop it.By many people died.
So after that.Every sentence in book need examination.And now,every sentence on internate need examination.
Of course,normally it seems dosen't exist.But on some business platform,business dosen't do examination.They just delete what they want.Of course it's not illegal,but this behavior hurts our feeling,so we want go to some place we can talk(of course in legal part)
