Sounds like "走火入魔", a mental state mentioned in many Wuxia/Chinese-Kongfu-Fantasy novels when a rigorous 内功修炼(internal training/meditation)goes bad, which I thought was a myth.

I can't visit the link. (https://zh.greatfire.org/blog/2014/nov/china-just-blocked-th...) And I'm in mainland China. What can I suppose?

Yes, and this article itself has been blocked too.

I'm a Chinese software developer. In China, VPN or other proxy tools are essential for anyone who need look up serious technical materials online. We call it "翻墙"(Go Over the Wall), which is a basic skill.

And about the reason why these sites are blocked: just BECAUSE THEY CAN! (They even blocked github for mysterious purpose once!) There is no public rule/law/principle to tell us why a foreign site is blocked. The just kill sites silently and pretend nobody cares.

Fortunately enough, HackNews has not been blocked, yet.
