Did you read the article? Martial law was lifted in 1987. That's 38 years ago.
The PRC is still under this condition today. Say the wrong things about Xinnie the Pooh and you will be disappeared, martial law or not.
How much undocumented atrocities occurred in China that you can't even link a Wikipedia article to? And are you willing to accept what's written about the Tiananmen Massacre on the same site that you linked to? If not, then stop linking to a site that you don't believe in.
So its no longer an authoritarian government for 38 years now. Thanks for pointing that out!
In the mean time Xi is serving his 3rd term in PRC right now, or 4th? Ignoring the rules set up by his predecessors. And you think that's better?
