Facebook, Twitter and YouTube are out, but in China's vast and bewildering online universe you can freely read the New York Times or visit a favorite porn site.
People outside China who have read about Internet censorship -- thrown into the spotlight by Google's decision on Monday to close its mainland Chinese-language portal -- often imagine online life there is bleak and boring.
The reality is very different.
China's 384 million Internet users, the world's biggest online population, enjoy everything from gaming and celebrity gossip to teenage chatrooms, academic forums and illegal file-sharing sites.
English language media reports, some highly critical of Beijing, are usually as freely available as the hardcore pornographic sites the government regularly professes to crack down on.
But Twitter, Facebook and many overseas blogging sites are out because they allow rapid sharing of information, triggering the ruling Communist Party's fears of mass unrest.
Another touchy point for government censors are contested history, politics and religion.
Sites with more than cursory or officially sanctioned information about topics including the bloody 1989 crackdown on protesters around Tiananmen Square, or the banned Falun Gong spiritual cult, are usually blocked in China.
Total outage is however the weapon of last resort for a sophisticated censorship apparatus that wants to damp down dissent, while allowing room for commercial development.
