Correction, again. It turns out, you can see China's Great Wall from low-earth orbit, according to Gene Cernan. He'd know. I guess Colonel Yang Liwei just wasn't looking hard enough.
Confirmation of this comes from a person who knows what he's talking about.

He is veteran American astronaut Gene Cernan, the last man to walk on the moon, who logged 556 hours in space, of which 75 hours were spent on the lunar surface.

He told The Sunday Times when he was in Singapore recently for the Asian Aerospace 2004 show: 'At Earth orbit of 160km to 320km high, the Great Wall of China is indeed visible to the naked eye.'
NASA says no, Gene says yes. Who knows. Maybe I'll ask a drunk astronaut the next time I run into one at happy hour.
